Julie, Phil, Geary and all,

As for Kentucky:

In the past highway engineers didn't seem to care. Today the Kentucky 
Speleological Survey is getting weekly requests for karst information 
from construction companies, consulting companies and from the state.

When I was in graduate school, I lived in a trailer about a mile

large sinkholes right in the trailer park.
It would be interesting to see if their policy covers the building

Thanks!  I read this yesterday, and was surprised to learn that 
property (offices, homes), including vehicles, are NOT covered by 
insurance if damaged by a sinkhole. There is an exclusion 
specifically for sinkholes.  Granted, I live on the Gulf Coast, and 
the only sinkholes are on streets from underground leaking pipes. I 
got the impression from the article that this exclusion is national, 
not just in cave areas.

Re: [Texascavers] Rechargeable Batteries

2012-08-08 Thread Bill Walden
I have been using the same set of Energizer 2700 mAHh rechargeable 
batteries for at least 4 years for multiple caving trips per month in my 
Apex headlamps (at least 4 headlamps over the 4 years - the batteries 
have outlasted 3 Apex headlamps). I always charge these batteries the 
night before a trip because the charge will decay over time. Over the 
years the capacity has decreased from enough to last an 8 to 12 hour 
cave trip to about 6 hours. My suggestions:


   Don't consider buying rechargeable batteries at Wal-Mart - most of
   the packages of batteries they sell are not labeled with the
   capacity and if the package is labeled it is typically a low rating
   (less than 2000 mAh).

   The Sanyo batteries recommended by Marvin sound good. These
   batteries represent a new generation of nickle metal hydride
   batteries that hold their charge much better than my old Energizers.

   Don't buy nicad batteries as they have a memory effect.

   Carefully check the milliampere hour rating of the batteries. As
   mentioned most rechargeable batteries sold by Wal-Mart are not
   labelled or the capacity label is covered by the packaging. I will
   not purchase rechargeable batteries with a rating of less than 2500
   mAh. The most recent batch of AA batteries I purchased  are rated at
   2900 mAh.

   Best to use a slow charger rather than a fast charger. The battery
   charger I use is a smart charger - that is it senses the charge on
   each cell. Once a cell is fully charged, the charger switches to a
   trickle charge rate (enough to maintain the battery at full charge).
   My charger works off a 120 volt wall outlet or a 12 volt automobile
   outlet. Charge batteries day before a cave trip to maximum duration.


I use the nickel metal hydride AA batteries for my photo equipment: 3 
floodlights each requiring 6 AA batteries, 4 strobe lights each 
requiring 4 AA batteries, and 3 high intensity LED flashlights each 
requiring 2 AA batteries (With the reflector removed these flashlights 
are great for macro photography!).

Geary,

A good starting place to purchase NiMH batteries is Amazon.com. They 
carry the Sanyo Eneloops that Marvin mentioned but they are only rated 
at 2000 mAh. I've had good luck with GP, Kodak, and Energizer all rated 
at 2500 mAh or more. The GP and Kodak batteries hold their charge longer 
than the Energizers but since I always recharge before a cave trip That 
doesn't bother me. A couple GP batteries (out of 12) and an Energizer 
(out of six) have gone bad over the years but that won't stop me from 
purchasing more.


I purchased a dozen Power2000 2950 mAh batteries for my flood lights. 
Even though reviews are poor, they work well in that application. These 
are less than a month old so not too much experience with them yet.


BTW the property I told you about that contains Coal Trace Cave and 
Barefoot Saltpeter Pit has now paid for itself. The owner has recouped 
the purchase price from timber sales from the land. Neither the original 
owner nor I thought there was enough mature timber to harvest. We were 
wrong!

I am interested in making the change to rechargeable AA and AAA
Batteries for my cave light and for electronic strobe. Anyone got
any opinions on how they compare to the Alkaline Batteries. Do the
new rechargeables have the memory problems of the past? Do they
last as long and preform as well,  and what brand is the best.

Rafal,

To much carbon dioxide will kill. A friend and I were surveying a cave 
that floods drastically years ago. As we surveyed I began to develop a 
headache and to feel nauseous. Finally my carbide light began to 
misbehave, so for some reason, I climbed up higher to change carbide. 
The lamp flame steadied some. I looked down at my survey partner I 
noticed that he was just fumbling with his lamp. At this point I 
realized what was wrong - high carbon dioxide content. I yelled at him 
to climb up to my level. He did. After he changed carbide, we left. Once 
out of the cave the headache and nausea went away. I never did complete 
the survey and never did go back to that cave.


The CO_2 was probably from the huge piles of rotting leaves throughout 
the cave.


CO_2 levels:

OSHA safe level - 0.5%
Max. short term exposure limit (OSHA) - 1.5%
Start to get a headache - 2%
Breathing twice normal rate - 3%

 Folks,

 I agree with Bill, when using solvent based paints (or for that
matter, any hazards material) in a confined space, it is much
quicker, easier and cheaper to use humans to determine if you've
exceeded any health related chemical thresholds verses real time
air monitoring or canaries. Most of the time, most folks become
violently ill before they actually die. While this is not the
recommended method by the American Council of Governmental
Industrial Hygienists, it seems to be the technique most often
used by industry. When employees get sick, it is probably time to
give them at least a 15 minute break. You don't have to worry
about long term exposures such as an increased risk of lung or
blood cancers as those folks probably won't be working for you in
20 years anyway so not your problem.

 Matter of fact, with substances such as asbestos or silica dust,
by allowing humans in a contaminated work area without
respirators, they actually help clean the air as the lungs retain
some of the asbestos fibers or silica (good for the room, bad for
the lungs). If you would like to see an excellent presentation on
silicoses and the Hawks Nest Tunnel in West Virginia and the

The one arranged for this coming January, 12th Multidisciplinary

of Karst, lasts three days and costs $495. There are a couple of 
short courses offered at an additional charge that amounts to $50 an 
hour ($250 or $375 dollars), which ought to buy you a private 
instructor, but no doubt doesn't. The organizers have arranged a 
special conference rate at the hotel of just $84 a night, plus 15% 
tax. Extra copies of the proceedings CD, which will cost less than $1

Admittedly, there are discounts for students.

the voice signals can penetrate. An interesting aside, however, is that they 
also state that US Special Forces paid them $5.7 million for a special

meters of any material (soil, rock, etc.) to remotely detonate explosives. A

Re: [Texascavers] carbide vs LED (attempt 2)

2010-06-13 Thread Bill Walden
While surveying a cave in southern Kentucky years ago, well decades ago, I 
developed a headache. After a few more shots down and into a room with a huge 
pile of rotting leaves, my carbide lamp started acting up. For some reason I 
climbed up high and onto a ledge to change carbide. The lamp still had plenty 
of good carbide. I looked down at my companion and noted he was fumbling with 
his carbide lamp and not accomplishing anything. At that point I realized what 
was wrong and shouted at my companion to climb up where I sat. Once he climbed 
up to my level his carbide lamp started to burn properly. We beat a hasty 
retreat. My headache went away once we were outside the cave. 

That same year I remember survey trip to another cave. We had a high school 
student with us, who was a student of the 3rd member of the team. The student, 
Paul, had a brand new waterproof pack. As we were preparing to leave for the 
day, Paul decided to change carbide. We were next to the cave stream. As Paul 
opened his pack there was a tremendous explosion. The blast burned all the hair 
off Paul's face and his face was bright red with black soot. We washed his face 
as quickly as we could with the cold stream water. He complained of pain from 
the burn. By the time we got to town Paul didn't  feel the need to visit a 
doctor or require any pain ointment. The red color had pretty much gone away. 
By morning he was fine albeit minus facial hair.

When I first started caving, one could buy carbide at a local hardware store, 
either in bulk or in a can. I bought a 100 pound drum of carbide which I shared 
with fellow cavers.

I've had two Princeton Tec LED lights go bad - an Apex and an EOS. Princeton 
Tec replaced both under warranty without question. If you get the Princeton Tec 
lights wet inside, just open them up to get the excess water out and re-close.  
Once home or back at camp, open the lamp up and allow the circuit board to dry.

For about ten years I was building my own LED head lamps for caving.  I made no 
attempt to waterproof the lamp or electronics other than a conformal coating on 
the circuit board. The LED element was mounted on a home made aluminum bracket 
(bolted to the helmet) that doubled as a heat sink. The circuit board was 
mounted to the back side of the bracket. The fixture was submerged many times 
and was never affected by being wet. The typical arrangement consisted of one 
Luxeon 1-watt LED and four super bright 1/8 LEDs all mounted on the aluminum 
bracket. (Very much like the Apex arrangement.) Other than having to replace 
the switches, I never had any problem with those head lamps.  I considered them 
a big improvement over the Nite Lite that I previously used and definitely an 
improvement over a carbide light. I continued to carry my trusty Autolite for 
backup and for placing survey stations. I never had to use it as a backup and I 
eventually started using either a Sharpie or red fingernail paint to mark 
stations with a very small dot. I haven't carried a carbide lamp for years now.

I was lucky to work for a company that permitted and encouraged employees to 
work on personal projects during their lunch hour and outside of working hours 
and allowed them to take parts from open stock without charge. Parts taken 
from controlled stock had to be signed out and judgment used as whether or 
not to reimburse the company. Our quality assurance manager was always happy to 
make custom circuit boards for employees. (I think that he had too much free 
time available.)

My best to all,
Bill Walden

To Fofo and all,

With reference to phd comics! One can easily prove any two numbers equal. I 
remember this from high school days ugh, 50 some years ago:

Given:



One can maintain the equality of an equation as long as the same operation is 
done to both sides.

 

a+b=cMultiply both sides by (a-b)

 

a2-b2=ca-cbSubtract ca from both sides, add b2 to both sides

 

a2-ca=b2-cbComplete the square by adding c2/4 to both sides

 

a2-ca+c2/4=b2-cb+b2/4   now take the square root of both sides

 

a-c/2=b-c/2Add c/2 to both sides

 

a=b

 

Beautiful -- right?  Try substituting real numbers such as 2+3=5 and maintain 
the format. Results: 2=3.

What does this have to do with caving?? It sure could screw up our surveys!

I bet the press would have fun with this.  

OK where is the fallacy?

  At 2:00 this afternoon, the USFWS issued a call for a moratorium on caving in 
all WNS-affected states and adjoining states - basically, Maine to Ohio, to 
Kentucky, to North Carolina.

  Here is their statement and a link to more info.

  Cave activity discouraged to help protect bats
  from deadly white-nose syndrome
  White-nose syndrome, a wildlife crisis of unprecedented 
proportions, has killed hundreds of thousands of bats from Vermont to West 
Virginia and continues unchecked.  Now, the U.S. Fish and Wildlife Service is 
asking those who use caves where bats hibernate – called hibernacula – to take 
extra precautions and to curtail activities to help prevent the spread of WNS.
  There is no known human health risk associated with white-nose 
syndrome in bats.  While the actual cause of WNS is unknown, scientists are 
reasonably certain that WNS is transmitted from bat-to-bat.  However, WNS has 
been found in caves a significant distance from WNS-affected hibernacula, 
leading scientists to believe that something else is moving WNS.
  “We suspect that white-nose syndrome may be transmitted by humans 
inadvertently carrying WNS from cave to cave where bats hibernate,” said 
Northeast Regional Director Marvin Moriarty of the U.S. Fish and Wildlife 
Service.  
  In addition, federal and state scientists will evaluate all scientific 
activities in hibernacula for their potential to spread WNS, weighing potential 
benefits of the research against the risk to bats.  
  “We are working closely with state natural resource agencies, the caving 
community, conservation organizations and other federal agencies on this 
issue,9 D Moriarty said.  “We understand that following these recommendations 
will inconvenience recreational cavers, but we believe this is the most 
responsible course of action as we face this unknown threat to bats, which play 
an important role in our world.”
  The Service’s cave advisory will be posted at 2 p.m. at http://www.fws. 
gov/northeast/ white_nose. html.  
  The U.S. Fish and Wildlife Service works with others to conserve, protect, 
and enhance fish, wildlife, plants, and their habitats for the continuing 
benefit of the American people. We are both a leader and a trusted partner in 
fish and wildlife conservation, known for our scientific excellence, 
stewardship of lands and natural resources, dedicated professionals, and 
commitment to public service. For more information about our work and the 
people who make it happen, visit http://www.fws.gov.
  Questions and Answers
  U.S. Fish and Wildlife Service Cave Advisory
  March 26, 2009
  What is the U.S. Fish and Wildlife Service recommending in its cave advisory? 
  The Service’s cave advisory has four recommendations to limit the possible 
spread of white-nose syndrome by human activity: 
  A voluntary moratorium on caving in states with confirmed WNS and all 
adjoining states;
  Nationally, in states not WNS-affected or adjoining states, use clothing and 
gear that has never been in caves in WNS-affected or adjoining states;
  State and federal conservation agencies should evaluate scientific activities 
for their potential to spread WNS; and
  Nationally, researchers should use clothing and gear that has never been in 
caves in a WNS-affected or adjoining state.
  This also applies to mines used by cavers.

   What is the timeframe for this cave advisory?
  We are not placing a time limit on this cave advisory.  Scientists are 
working to determine the cause of WNS. We do not know when we will have answers 
to how WNS spreads. Whatever is causing WNS may remain in caves where bats 
hibernate (hibernacula) even when bats are not present, and we are concerned 
that people may inadvertently carry WNS out of the cave with them.  We intend 
to review the cave advisory frequently – at least quarterly.

   What proof do you have that people are contri buting to the spread of WNS? 
  While we do not have conclusive proof, the leapfrogging pattern of WNS spread 
suggests that humans may be contributing to the spread

[Texascavers] Cave Property for Sale

2009-03-02 Thread Bill Walden
I just learned that a 234 acre (approximately) property in Wayne County, 
Kentucky is for sale. The property contains two caves: Coal Trace Cave, which 
has the second largest cave room in Kentucky, and Saltpetre Pit. Saltpetre Pit  
is approximately 124 feet deep. It was mined for salt petre in the early 1800's 
and for guano through the 1920's. Local farmers used the guano for fertilizer. 
I first visited Saltpetre Pit, which we named Barefoot Pit because an 8 year 
old barefoot girl led us through briar patches up the hill to the cave, in 
1972.  Paul Unger and I dropped the pit that year and started to survey it. The 
cave contained a few artifacts from the salt petre mining days and drawings on 
the cave wall left by the miners. It is an interesting cave. I plan to visit 
the cave next week (3/8/2009) with Fish and Wildlife people to do a bat count.

If any cavers are interested please contact me for additional information.

Re: [Texascavers] NSS Convention

2008-07-28 Thread Bill Walden
Philip,

I cannot agree more!

I don't think that the NSS has done anything or failed to do anything to retain 
and attract members. I've noted that service clubs are having the same problem 
and that started with the 1990's or late 80's. The grotto to which I belong, 
The Central Ohio Grotto (COG), is down to just a few members. It has always 
been a project oriented club surveying the caves in Kentucky -- a club of cave 
surveyors. It was COG members that founded CRF. COG member Jim Dyer chaired the 
NSS Photo Salon from 1962 - 69. He died (1970??). Ed Herel took the salon over 
after Jim died and was salon chairman from 1970 - 78 (doesn't agree with the 
NSS WEB site listing which I think is in error). Those years the COG always had 
a preview of the salon for the June meeting and almost every COG member 
attended the NSS Convention. We had a lot of dedicated cavers. The grotto was 
active in cave surveying and with the NSS. The NSS convention was the main 
event each year for club members.

I've joined another grotto that is very successful. They have a lot of  
organized sport trips,  don't have any survey projects, and have really great 
parties. While fun, the grotto has no cave projects. They do have several 
members who regularly help with my survey projects - hence my reason for 
joining. 

What happened? 

  Perhaps staying connected to one's job has affected some people. Late in my 
career I got a new boss who wanted to be able to contact me at any time. Not 
possible I told him. I'm always out of reach on weekends. Cell phones don't 
work where I go! He never liked that. Tough!

  Organized kid activities appear to take more parental time than ever today. 
The list of activities through the seasons seems endless. With my family caving 
was the kid activity! My daughter was caving before she was born! Once born we 
used to put her in the backpack carrier and take her into the caves on easy 
survey trips! She was always real quiet and wide eyed!  Now married and a 
professional, she is still caving.

  I suspect modern electronics may play a role too. Many people spend way too 
much time on the computer or playing electronic games.

Add the above together along with factors I haven't thought of and the result 
is less time spent on service oriented organizations.

Cave surveying continues in south central Kentucky but most is being done by 
individuals and not by grottos. Most of us project leaders are in our 40's and 
up in age. Most are driving 4 to  6 hours to get here. Me, I retired to Wayne 
County, Kentucky so I can cave more!

See you all in Lake City,

Bill Walden

 The opinions offered below are my own.
 I hope the NSS never shows the photo salon or any other convention
 activities live.  NSS membership retention (not recruitment as many would
 have you believe) is way down.  From the mid-1960s to the mid-1970s, the
 NSS Convention had attendance that was equivalent to 20% of the
 membership.  Since 1976, the largest convention has been equivalent to
 14% of the membership and many have been under 10%, although at least one
 flaw in my model is the fact that membership retention did not plummet
 until 1995 (Does anybody know what it was the NSS did in 1995 or possibly
 1994 to so disaffect its members?)  It is my opinion that membership
 retention is affected strongly by personal interaction among the members.
 Convention attendance is one of main things that separates a committed
 member from a magazine subscriber.  The NSS can not thrive by having any
 number of subscribers to the NSS; there are way too many activities that
 the NSS depends on volunteers to run.  Voting generally tracks the
 attendance at the previous convention.
 
 I believe that conventions are the glue that holds the NSS together and
 we need more glue, not less.  The more one can get the benefits of
 convention without attending and having the personal interactions of
 actually attending, the poorer the NSS will be.  People who routinely
 attend NSS conventions are more likely to volunteer their time, donate
 their money, and vote for Directors.

  On the other hand perhaps the decline in NSS retention post 1995 is 
because the NSS directorate is holding on to a rosy nostalgia of driving across 
the country to meet their friends at a convention as the glue that holds the 
NSS together; while the general society is moving to digital interaction. 
Cavers along with everyone else increasingly see little need for everyone to 
gather in one place; and perhaps, given the time and expense as even 
counterproductive.  Retention in any group is affected strongly by personal 
interaction between the members, but having to drive across the country to do 
this would appear to be a strategic weakness. 
  In the digital age one should not have to attend a convention to be a 
committed member.  It might be to increase retention we need to find 
directors that are more comfortable with digital interaction.  They will spend 
the time and energy to make the digital NSS more than a magazine subscription.

The immense on line resource is designed to greatly enhance our

The creators of the database say it could have an impact on human

It is designed to be used by everyone from scientists to lay readers.

Gee, how many DC3's are still flying! The DeLorian was stainless steel. 
There was a version of the Jaguar XK150 that was aluminum. I recall that 
my college roommate's older brother had one. The body was cast aluminum! 
I believe those aluminum bodied Jags to be rare.


I see no reason why the average family car cannot do better than 40 
miles per gallon.  I'm driving the second car that I have owned which 
gets better than 50 miles per gallon.  The first was a Nissan Sentra 
with a 1.9 liter diesel engine. The worst that it did was 44 miles per 
gallon in town and best for an extended trip was 53.5 miles per gallon 
on a trip to the Yreka, California NSS Convention from Columbus, Ohio. 
My current car is a VW Jetta diesel. I'm disappointed when it gets less 
than 50 mpg. The worst the Jetta has ever done on a tankful was 46.5 
mpg. Todays diesels are a lot cleaner burning than those of the previous 
century and the thermal efficiency far exceeds that of gasoline 
engines.  Of course both of these cars have manual transmissions.  The 
same models with automatics get poorer fuel mileage and lack the pep of 
the manuals.  Americans may just have to learn how to drive cars with 
manual transmissions.


Hybrid cars allow the heat engines to run near peak efficiency and thus 
achieve better fuel mileage.  But, none of the current production models 
(in real life) match or exceed the VW Jetta diesel with a manual 
transmission. Where are the diesel hybrids? Europe and Canada have them 
but not the USA. Battery power cars - will never have the range. Besides 
that is just displacement of the point of pollution, same for fuel 
celled cars. All that extra battery weight kills efficiency. Fuel cells 
do not yet equal the thermal efficiency of the best diesels. I don't see 
them as practical until they can run efficiently on methane. The problem 
with hydrogen fuel cells is the production of hydrogen.  Two ways: 1) 
electrolysis of water. 2) cracking hydrocarbons.  Either technique 
requires a lot of energy (fuel - probably coal).


There are emerging nations that have populations three and four times 
that of the United States.  They are beginning to drive more and more 
cars and trucks.  How can we continue to release stored solar energy 
into the atmosphere? The solution might be with using renewable 
resources. But these must require far less energy to grow and process 
than they provide.  Corn is not the solution! Trees???


Now just to make this a caving forum I discovered over 3000 feet of 
large virgin walking passage in the cave system I have been working on 
for the past 10 years.  Everyone thought the area caved out.  
Persistence pays off. Best of all the entrance is within 100 feet of 
where one can park a 4X4 vehicle. Down side: One must work his way 
through a breakdown maze. I expect to find much more there this coming 
weekend.

[Texascavers] Beer bottles

2007-10-29 Thread Bill Walden

Louise and all,

I accidentally knocked a bottle of beer from the garage refrigerator 
Friday evening and the bottle shattered into hundreds of sharp pieces. I 
lamented the loss of a beer particularly because I live in a dry area of 
KY.  My house overlooks Otter Creek and we have a really nice beach 
below the house. The beer of choice for the litterbugs is clearly Bud 
Light in bottles, many of which are broken.  The beach is a popular 
swimming hole. Glass beer bottles and beaches don't mix.  I cannot count 
the number of  heavy duty contractor bags that I have filled with Bud 
Light bottles and a few Miller beer bottles from the beach.


The type bottle you mention would be great.  What kind of beer?  Perhaps 
we could encourage Anheuser-Busch and other companies to adopt such bottles.


Best to all,
Bill Walden



Haven't seen this in the PacNW, but I have to agree w/Mark. Probably a 
marketing gimmick.


Mark said: /Aluminum is almost certainly more environmentally damaging 
to produce than glass, but on the other hand, it won't break and leave 
sharp shards lying around.

/
Do glass beer bottles still make sharp shards? I dropped one on my 
concrete front porch last year and, after getting over the horror of 
wasting a beer, noticed that most of the bottle had crumbled into a 
sand-like consistency. No sharp corners, even on the bigger pieces.

This is really old news, but it is caving related
because most cavers like beer, and many
cavers in the world consider beer a part of their after-cave-trip
celebration.


All the young preppies here in Houston
( and the Britney Spears wannabes ) seem to prefer
their beer in an aluminum bottle?

I haven't tried one yet, and I wouldn't be a fair tester
as I have never acquired a taste for beer.

What is up with the aluminum bottle?

Is the only benefit, colder beer? Or colder beer for
less energy?

Is that better for the environment than a glass bottle?

I assume this has caught on nationwide.

Does the top screw back on? That could be a benefit.

If there were an occasion to take beer in a cave, then
having it in an aluminum bottle would be ideal, right?
( like during the tuxedo caving trips )

Re: [Texascavers] LED Primer

2007-10-21 Thread Bill Walden
Don, assuming each diode has a voltage drop of 3.6 volts, your series 
string of 40 would have a voltage drop of 144 volts at rated current. (I 
assume 20 mA)  The red dot marks the positive terminal of the capacitor. 
At only 20 mA the capacitor may level the voltage closer to the peak 
value of the voltage You may want to use a 1000 ohm resistor and two 
capacitors - one on either side of the resistor - a pi network filter. 
Use a 1/2 watt or greater resistor. Using a multimeter check the current 
in the circuit.  Meter should be in series with the LEDs. Adjust the 
value of the resistor to keep the current at or less than the rated 
current for the LED's.


Check the spec sheet for your LEDs for actual ratings.

Best regards,

Bill Walden

It's a fairly bright and efficient light (probably).  Unusually

(only vertically aligned objects in the room have defined shadows - 
this might make an interesting way to light cave formations!)
Hooked up to AC - the flicker is a bit bothersome.  But making it on 
all the time using a capacitor to reservoir the voltage, it will 
appear much brighter.  (A beefier load resistor might be in order to 
maintain the constant rather than flickering wattage).


QUESTION: I found a big 820uF cap - rated at 200vdc.  But it does not 
have clearly marked pos/neg terminal.  There is red paint on the base 
rivet that holds the terminal on.

Is that the Negative or Positive side?

Re: [Texascavers] OT - the new diesel Jeep Cherokee

2007-10-11 Thread Bill Walden

David,

I still have my '78 Scout.  I'm thinking of converting it to diesel.  
The engine is still available but a little bigger than the 1978 - 1980 
engine. It is a Nissan 3.6 liter turbo charged 6 cylinder diesel -- 
$5000 and is complete drop in replacement. Reports say 24 to 26 mpg. 

Occasionally Super Scout lists a rebuilt Scout diesel for sale.  Check 
their WEB site: http://www.superscoutspecialists.com/store/



Bill Walden

David Locklear wrote:

I test drove the new diesel Jeep Cherokee yesterday at the dealer.

You wouldn't know it was a diesel unless you opened the
hood and listened to it run.  With the hood opened, it was
still fairly quiet for a diesel.

The only style difference is the word DIESEL underneath
the model's name on the rear hatch.It did not have the CRD
label on the body anywhere.   Maybe on the plastic engine cover.

http://z.about.com/d/suvs/1/0/_/Q/-/-/Engine.jpg

They had 4 of them on the lot ranging in price from $ 42,000
to nearly $ 44,000, and none had 4 wheel drive nor any of
the off-road package options.  It had a sun-roof, and not
just a moonroof.

The fuel tank is 22 gallons, only a few ounces bigger than
the gas version.

It does not use Mercedes latest diesel emission technology,
but is built in Berlin.

EPA mileage estimates were 18/23 for the 4x2 model with
street tires.

I think the only other SUV you could compare it to would be
the 1980 diesel International Scout 2, which was the 1st
readily available SUV to put a turbo on the diesel.The
differences though are quite dramatic.The Scout only
had 2 doors and a 4-speed transmission and none of the modern
gadgets of the new
Jeep like Stereo/DVD, Sunroof, power steering, quietness,
torque, horsepower, etc. The Scout had a solid front
axle and leaf springs. But it did have a removable top
and a real tailgate. The turbo-diesel Scout is extremely rare,
and keeping one running can be a full time job.   ( I couldn't
find one on the web, although there are a few gas powered
Scouts on E-bay motors. )

Since Jeep sold 11,000 diesel Liberty's, I would expect them
to try to build at least that many Cherokees, so they should be around
for many years to come.[  I don't know how many turbo-diesel
Scout's were manufactured, but the total number of all 1980
Scouts was only around 13,000. ]


You could also try to compare it to a diesel Toureg, or a Ford Excursion,
but I can't think of any other SUV's that are readily available
that have a turbo-diesel, except the humongous MXT.

One of the reasons to consider a Jeep is the choice of
aftermarket accessories.Jeep lovers claim that you don't buy
a Jeep, but you build a Jeep, or something like that. Another reason,
might be that someday you could rig it to run off of vegetable oil, or
Bio-diesel.


The stock Cherokee does not have a good departure angle, meaning
the rear hangs down low especially with a tow hitch. But this can
be overcome with a body-lift, suspension lift, bigger tires and a different
bumper, for another  $ 3,000. Then there is another $ 1,000 for a
better front bumper with winch.And then another $ 500 to upgrade
the roof rack.  So you are looking at way over $ 50,000 to get this
diesel Cherokee ready for the Sierra Madres. But then you have
another problem -   the diesel fuel in Mexico may not be compatible
with this new diesel emission parts.

To the best of my knowledge the turbo feature, does absolutely nothing
at low speeds, but does provide a noticeable boost once you step
on the pedal.

The diesel jeep has only a limited warranty package.


David Locklear


P.S. On E-Bay motors is a 1980 Scout 2, with a gas motor and
lots of off-road goodies.Bidding has just passed $ 2,000.It is
in Washington state. I am guessing if you could find a turbo-diesel
Scout and it was in good shape, that it would cost you around $ 7,000
or more. Here is one:

Re: [Texascavers] OT - LED's for the house and other stuff

2007-09-10 Thread Bill Walden

For LED's check this site:  http://www.theledlight.com/.

I have been using LED's for a caving light now since 1997. Until 
recently all were home built using the bulbs or elements from The LED 
Light. And yes, I use LED night lights in the bathrooms.  One can buy 
them today but the first ones I built by replacing the incandescent bulb 
with a resistor and one or two LED's.


Best to all,
Bill Walden


David Locklear wrote:

Are any of you using LED's in the house?

I have LED night-lights all over the house.

Fry's Electronics sells a $ 26 LED bulb that can
be used in household lighting systems. It is by Coast.It has 2 prongs
that fit into fixtures like accent lighting.  It resembles the photo below:

http://www.ledshoponline.com/images/highpowerMR16th.jpg


Also, Lowe's has a desk lamp
with about 30 small LED's in it that has a small screw in socket like
on chandeliers.I have not seen this bulb sold separately, but the
lamp is $ 30.

Here is a company that sells the kind of LED bulbs that you can
put in your household light sockets. But check out the prices.
Ouch!  But maybe mixed with dimming light switches, you could
save some money on electricity. In 10 or 20 years, the bulbs
would pay for themselves.Right? And in the long run, you
would be helping the environment.

We had some el-cheapo LED solar-powered lights around the sidewalk,
but they all crapped out after about a year, apparently due to moisture.
Do the more expensive ones work any better?

And on a slightly related note,

We have been using the curly flourescent bulbs for years now, and I
can't remember any of them ever burning out. They seem like
great investments. Our electric bill isn't that high because we
have gas appliances. If we could just figure out a way to make
our AC and washing machine use less electricity, then we would
could lower our monthly utility bill.


Which reminds me,

I lived for many years without
an air-conditioner in Texas.In the summer-time growing up, we would just
take a cold shower before going to bed, open the window and put a fan
in the window and sleep with just a cotton sheet or with nothing.
I imagine many of you remember such times.

There is a recent county song by Bucky Covington called A Different World
about those being not different times but a different world,
but he doesn't mention living without AC.

It seems to be a popular song on the radio.
I think it would have
sounded better sung by John Anderson, and
retitled: Defurnt Whirl'd.   ( remember:   And we were swangin )

Re: [Texascavers] Off to OTR--NOT

2007-09-04 Thread Bill Walden
Go to OTR or not? Never been to OTR in 40 year of caving. I always use 
Labor Day Weekend for caving.  Yes, I'm sore today!  BTW, I was caving 
with a Texas caver (Kevin Toepke) over the weekend but in Kentucky. 
Managed to get a few feet of virgin cave surveyed in two caves.

Re: [Texascavers] RE: Off to OTR--NOT

2007-09-04 Thread Bill Walden
True, I think that my daughter actually does caving at OTR. However, 
here in southern Kentucky late summer through mid autumn the ground and 
caves are normally dry and my project caves flood. So, Labor Day Weekend 
is ideal for surveying in caves that flood. This year we are suffering 
from severe drought - an ideal time to survey caves are not normally 
accessible. We have not had any rain, other than a few drops that have 
left muddy rings on the car windshield, since mid May. Sunday as we left 
the cave, we chatted with the owner. I noted that his cattle herd is 
smaller. He replied that he has sold off half his herd and will be 
selling more because he doesn't have enough hay. He only got 75% normal 
yield from his May cutting and none since. He owns 6000 acres in the 
bottom of the sinkhole. (Some call it a pseudo polje or blind valley. I 
call it a sinkhole to annoy the owner - we are good enough friends that 
we attend each other's birthday parties.) The rim of the sinkhole is 
rimmed with what I call cave couplets. There are 20 pairs of which I am 
aware. The final swallow hole frequently clogs following heavy rains and 
a lake 2 miles long can form in the sinkhole.


As for partying, that we did Saturday night.  I cooked two 2.5 inch 
thick sirloin steaks (12 pounds) over mesquite for cavers from Kentucky, 
Ohio, Florida, Tennessee, Texas, Wisconsin, and Romania. Of course we 
had plenty of beer, wine and rum too. The beverages probably helped us 
all laugh at the movie Borat later that evening. The caver from Romania 
said the people were speaking Romanian in the portions supposedly shot 
in Kazakhstan. We had a second party Sunday night at a cave owner's 
house while the owner was in Calgary. We have good land owner relations 
here.  They gave us their house key  so we could have a party there.


Happy caving,
Bill Walden

  One can certainly do both.  Lots of folks go caving during OTR.  
I did.  In fact, because of a cave trip during OTR, Hellhole is now 
the 11th longest cave in the U. S. at 28.28 miles.  Not too shabby, 
and you still get to party!
