RE: Gear calculations

[bulkeley]

I scroll sawed all my custom gears it took a really long time too I generated 
the gear in a on line program all I needed was the distance between the teeth 
and the tooth count and it produced a pic of the gear which I glued to the 
metal plate then scroll sawed away.

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.

Dan - I'm impressed with the level of detail/calculations and questions you 
come up with.

 

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 
you are addressing here. 

However I have interest in what you are asking and how you will use the 
answer(s) - as well as how the rest of us will, as well, in our own unique 
situations.

Subject: Gear calculations

 

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.

DanK

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.

RE: Gear calculations

[bulkeley]

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 
rocket science to you.

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!

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.

Re: New project in the works.

['Curt George' via Legacy Ornamental Mills]

 Good morning Ed.
What Legacy modal do you own? 
Owning a second hand machine may offer you some very real benefits that you 
arenot aware of. And of a matter of coarse there may be still some MOD's that 
you will/ could add to your machine, to make it your own.
Feel free to ask and or add to any topic offered. That's why this group was 
made, so every Legacy user could lean and grow form the conversations with 
others who users.  The Legacy is a good machine, but there is a learning curve 
that needs to be understood, and explored by every user/owner of the machine.  
Who knows that one trick or method freely offered, just might help others who 
are running into a problem, what may be common since to you, may not be for 
others.So be sharing we "ALL" can grow form the experiences.
Have a good day.

The template follower is one of the most under used tool on the Legacy, I never 
really figured out why most people do not use it.At the first I tried to use 
the template follower when I bought my Legacy 1000ex, I found it hard to adjust 
and it often slipped when in use. So my first MOD. was to re-make the follower 
to give it more support and easer adjustment.  (pix's 1&2,) Photo of the Wood 
Chuck/Legacy template follower, #2 my fist MOD. with the template follower.This 
new Mod. worked well, but I did not like the template so far away form where I 
was working form, So I moved it to the front of my machine. as well as giving 
it even more control, by using a router jig (sold at Rockler woodworking.) Now 
I still found that I had some problems using this template follower.Problem #1 
stiffness of the X axis. It was hard to move the carriage and control the Y 
axis movement, at the same time.I fixed this in two ways. #1 I added handles on 
both movements for control, and #2. I found, that I did not need to control the 
X movement since I had a motor drive, I just let the motor do its thing, so I 
only needed to control the Y Axis movement, this made things much easer.  NOTE: 
three photo of my last MOD. done on my 1000ex.
NOW How to use the template follower.If you have a motor control it makes life 
much easer, but it is not nessasary to have in order to use the follower.
NOTE: different mind-set.  I own a lathe and use it with the Legacy on 
different jobs. I find both machines work very well together/better then either 
machine dose independently.  I LIKE adding details with the Legacy, So a lot of 
the rough work is done on my lathe. the fine details are done on the Legacy, 
like roping and fluting/reeding...  For me this is where the template follower 
works for me.
Now I can do everything with the follower if nessasary, but it will take longer 
and honestly it just dose not give me the look I am always trying to achieve. 
(fine details/sharp lines/cuts are not there, they are more rounder.)
NOW cutting form the side will give you the profile more like a lathe, and 
using the  template follower will also help you control the movement/shape of 
the spindle.
NOTE: More light cuts will always give you better results over LARGE Cuts, 
which remove to much material. (Speed vs quality.) 

Im sorry I need to stop here. 
MORE LATTER.

Hello Everyone.
