Is there a bette way to cut wheels and pinions
« on: April 16, 2007, 10:14:10 PM »
Hello there, I'm new to this hobby although I've been reading up on it for some time.  I presently use a scroll saw to cut my gears.   This works well but takes a beastly long time.  Is there a better way using some type of jig and router set up?  I saw and article in fine wood working that shows one method but I'm less then confident in it's accuracy.  Also is there a scaled down computer program that helps to design gears?  Any help would be apreciated.

computer programs for gears

There is at least one gear program available that isn't too expense and that does cycloidal gears.  I haven't used it but it is located at

Being a DIY sort of guy, I am nearing the end of development of a free simple gear program - it only does cycloidal gears and only outputs DXF and printed versions, no G-code.  It's basically working but I'm finishing up the portion that generates a printed version to scale and I need to build a help file.  I did this program as an exercise in learning Python and just wanted the basics - DXF so I could export to my CAD program and printing so people can print a gear pattern to use with a scroll saw.  It just has the gear teeth and arbour hole so people have to do the crossing out on their own - I intend to export in DXF to my CAD program, do the crossing out there and then transfer it to a homemade CNC milling machine (when I get it built - so many plans, so little time)

When it's finished I'll post its availablility here, assuming there's some interest.

There are several available. TurboCad has one built in that works super. There is one available at  There is also one available at . There are a few other associated links on my website at
