Re: [Texascavers] Rechargeable Batteries
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!).

Re: [Texascavers] Rechargeable Batteries
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!

Re: [Texascavers] fumes in CC visitor center
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% Bill Walden NSS 11573 On 07/27/2012 10:32 PM, rafal kedzierski wrote: Carbon dioxide?

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.

Re: [Texascavers] fumes in CC visitor center
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% Bill Walden NSS 11573 On 07/27/2012 10:32 PM, rafal kedzierski wrote: Carbon dioxide?

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

For those of you who don't have much experience with low O2 in caves, it can be highly stratified in caves. I have had my head in 15% 02 while at my feet it was 9% (I had a meter that day).

Here is their statement and a link to more info. Peter (I don't know who Peter is but...) 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
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
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!

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.

Re: [Texascavers] OT - future of automobiles
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. Best to all, Bill Walden Kentucky Caver George Nincehelser wrote: A big drawback of aluminum is its metal fatigue characteristics.

The only automobile body made of aluminum that I can recall was a limited run of DeLorians which are now collectibles demanding big prices. I assume that Mr. DeLorian's personal problems led to the demise of the company. These cars were hailed as really high tech automobiles. I would like to hear from an informed source as to why no aluminum auto bodies with the manufacturer's quest for better gas mileage which would be aided greatly by weight reduction.

[Texascavers] Beer bottles
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.

Re: [Texascavers] LED Primer
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 .

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

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.

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.

Re: [Texascavers] RE: Off to OTR--NOT
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 Minton, Mark wrote: Bill Walden said: Go to OTR or not? Never been to OTR in 40 year of caving. I always use Labor Day Weekend for caving. 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!
