Index wheels

[Pete49]

I'm making a few missing index wheels for my faceting machine and while I was able to make the 40 & 48 tooth cogs I still need others. Is there software out there that will let me print out cogs the size and tooth count I need so I can stick them to the brass discs to file them out? Easily done with a 3 corner file as there is shape wise is a 'vvvv' shape and the 2 I have made are good to go so I figure I can make the rest if I can find a way to make the paper patterns. Any ideas?
The reason I'm making them is because money not so much (Aussie pension) time I have plenty of. Also I think the machine maker is gone its an old MDR.
Posted on onother site but fishing for ideas so the more chance of a method to use

Take a look at Gearotic - http://gearotic.com/

There are probably several other options worth considering too, might even be easy with a basic CAD system if you don't need teeth to mesh with other gears.

You might try :-

It's intended for wood gears, but it would be good for any material and what's more it's free!

Many, many uses possible! (No John it's not L**ux specific!)
