Yes, mine is 30" too, with a foot pedal switch accessory.  I had occasion to 
cut 

some 4' filigree panels for a client in Chicago.  A challenging wedding 
decoration!

I would think that cutting 1/8" mild steel would be stretching it's capability. 
 

But with the right blade, I may give it a try someday!  Gotta find the metal 
first. 

The brass,  bronze and decorative aluminum sheets cut really well.

Yes, mine is 30" too, with a foot pedal switch accessory.  I had occasion to 
cut 

some 4' filigree panels for a client in Chicago.  A challenging wedding 
decoration!

I would think that cutting 1/8" mild steel would be stretching it's capability. 
 

But with the right blade, I may give it a try someday!  Gotta find the metal 
first.

Re: Gear calculations

[cdkr...@gmail.com]

Yes, mine is 30" too, with a foot pedal switch accessory.  I had occasion 
to cut 
some 4' filigree panels for a client in Chicago.  A challenging wedding 
decoration!
I would think that cutting 1/8" mild steel would be stretching it's 
capability.  
But with the right blade, I may give it a try someday!  Gotta find the 
metal first. 
The brass,  bronze and decorative aluminum sheets cut really well.

Well we know you have the best scroll saw out there. Thats what Bill and I

bought it through Seyco, the Scroll saw specialists more the 15 years ago.
Great and accurate saw.

I searched and searched a LOT, but didn't get much. So thank you for posting

I used my Excalibur scroll saw with a very sharp #5 blade running at about 5

quickly and under 

those conditions it's easy to get very accurate, clean results.  The acrylic 
does not melt 

at that speed.  I've had decades of practice at very delicate detailed scroll 
saw work, and

I'm using it.

 

I'm pursuing my foggy inspiration about directly calculating the gear tooth 
counts needed to 

achieve a given ratio between the feed screw pitch and work piece pitch.  The 
current dynamic chart 

makes poke and hope guessing pretty easy and quick, but well, you know.  Target

Having confirmed the pitch chart calcs on paper, I printed one of the duplex 
gears and pasted it onto 1/8" acrylic. After 30 minutes or so of very patient 
cutting under magnification, this is what I came up with.  It feels very smooth 
against the factory driver.

Now that we have access to machines that generate the gears, the better the

I have been able to confirm the module number for the index gear as 2.08333 and 

have made a successful pattern that precisely matches the original index gear 

on the REVO.  So now I am about ready to test on paper the gears I think I need 
for 

the wooden threads. I'm excited because this pitch calculator allows quick 

determination of gear requirements for a required workpiece pitch. It still 
nags 

me that I haven't found a way to enter a required workpiece pitch and get the 

gear combos in the results.  So in the mean time, this works pretty well.

 

I have also found a way to edit the posted pitch chart so that I don't have to

deleting and posting new links.  So the previous links are broken, the latest

No worries, mate.  Bill can do math upside down and backwards.  I've just 
posted more updates.

  

My goal doing all this is to be able to easily extend the capabilities of my 
REVO LOM.  Specifically, the current shop project is restoring a wooden hand 
plane that needs wooden threads typical of the era  3/4 - 6  (dia - pitch).  I 
have a thread box, but it doesn't do well in the wood I have, so the REVO is 
called to duty. But the pitch required on the wooden dowel is not reachable 
with the standard gear set for the REVO even if I had all the gears made that 
would fit it.  So the simplest route turned complex-- make custom gears.  But I 
don't think I know anyone yet that can generate an accurate DXF file without 
knowing the module of the gears. A DXF file communicates the gear 
specifications from a drawing to a G-code generator that operates a CNC device 
of some sort, be it laser, water jet, machining, or 3D printer.  Any two gears 
that mesh must have the same module.  There are two modules used on the most 
common LOMs, one for driver gear (the little teeth) and one for the index gear 
(larger teeth).   

  

So a milestone has been reached.  Now I will be looking for ways to actually 
make the gear I need.  I have 1/8" acrylic sheets that I can scroll saw to 
shape.  I also have machining tools capable of gear cutting, i.e. mill and 
index head.  I'll poke around some before I get serious about hiring someone to 
make the gears, but I won't turn down leads.

 Hi guys,
 Can anyone confirm my calculations of module for the drive gears and
 index gears?

 I calculate:
 drive gear module = 1.05435
 index gear module = 0.09722

 These two numbers are in mm and are critical to the accurate production
 of gears to work on the LOMs, specifically the REVO.

 The formula I used is m = OD/(z+2) where m is module, OD is outside
 diamter, and z is the number of teeth.

 Thank you.

Hello Everyone!

 

This is beyond me TOO.  

How I did it, was to find a gear generator program, then match the Legacy's 
gears to find the tooth pitch and angles so everything matched up right. 

Then I used common math to find make the gear reduction ratio's that would work 
for me.

Here is a pix. of my chart.

No worries, mate.  Bill can do math upside down and backwards.  I've just 
posted more updates.

 

My goal doing all this is to be able to easily extend the capabilities of my 
REVO LOM.  Specifically, the current shop project is restoring a wooden hand 
plane that needs wooden threads typical of the era  3/4 - 6  (dia - pitch).  I 
have a thread box, but it doesn't do well in the wood I have, so the REVO is 
called to duty. But the pitch required on the wooden dowel is not reachable 
with the standard gear set for the REVO even if I had all the gears made that 
would fit it.  So the simplest route turned complex-- make custom gears.  But I 
don't think I know anyone yet that can generate an accurate DXF file without 
knowing the module of the gears. A DXF file communicates the gear 
specifications from a drawing to a G-code generator that operates a CNC device 
of some sort, be it laser, water jet, machining, or 3D printer.  Any two gears 
that mesh must have the same module.  There are two modules used on the most 
common LOMs, one for driver gear (the little teeth) and one for the index gear 
(larger teeth).   

 

So a milestone has been reached.  Now I will be looking for ways to actually 
make the gear I need.  I have 1/8" acrylic sheets that I can scroll saw to 
shape.  I also have machining tools capable of gear cutting, i.e. mill and 
index head.  I'll poke around some before I get serious about hiring someone to 
make the gears, but I won't turn down leads.

Please explain - once you know the module - how do you employ/use it?

 

Glad you asked the question - but, as you can tell, I have no clue as to what

Re: Gear calculations

[cdkr...@gmail.com]

In short, once I get the index module confirmed, yes.  Very accurate 
gears.  

I found an error in the module for index gears. I fat fingered the data 
input to the formula and it's wildly wrong as posted. Google won't let me 
edit the posting, so I have to upload another copy and post the new link.

Sorry Dan your starting to get outside my expertise I’m a trial and error man I 
would take a guess 3d print the gears try and measure the pitch with a dial 
indicator and adjust the dia and tooth count to suit I will have to leave the

Re: Gear calculations

[M.W.Foscue]

Dan,

Thanks.  The "fog" is clearing.
Making a gear or two for a 1-off or 3-off project seems like a way to go - 
given what you've shared.
If needing gears for a "long haul", my guess is pony up the pennies and farm 
the project out to Tim Z's brother - as he is aa machinist (or at least owns 
the machinery and has the skill set.

Best of luck to ya!
Mac

(larger teeth).   
 
So a milestone has been reached.  Now I will be looking for ways to actually 
make the gear I need.  I have 1/8" acrylic sheets that I can scroll saw to

Hi guys,
Can anyone confirm my calculations of module for the drive gears and index 
gears?
 
I calculate:
drive gear module = 1.05435 
index gear module = 0.09722
 
These two numbers are in mm and are critical to the accurate production of 
gears to work on the LOMs, specifically the REVO.
 
The formula I used is m = OD/(z+2) where m is module, OD is outside diamter, 
and z is the number of teeth. 
 
Thank you.

Hi guys,
Can anyone confirm my calculations of module for the drive gears and index 
gears?
 
I calculate:
drive gear module = 1.05435  
index gear module = 0.09722
 
These two numbers are in mm and are critical to the accurate production of 
gears to work on the LOMs, specifically the REVO.
 
The formula I used is m = OD/(z+2) where m is module, OD is outside diamter, 
and z is the number of teeth.
