However, if you want (or need) to make your own sprockets, I would recommend downloading the Martin catalog PDFs ( http://www.martinsprocket.com/suppor...atalog-online). The materials and dimensions of the sprockets should all be in there. You should be able to fabricate your sprockets from there.
One recommendation would be to use a hardenable steel and flame-harden the teeth. A lot of sites abound on the web that can advise you how do do it properly. As always, safety first ...  |
This is all true, but is way overkill.
Sprockets for FRC use can be cut by just about any 2d method (CNC router, mill, waterjet, laster) into 6061 Aluminum plate and be just fine. The cut time isn't crazy high to do so either.
