Thanks for posting this.  I have two completely unrelated questions, perhaps both silly.

Could you grind arbor-type involute gear cutters?

Can you tell me how you achieved the paint/finish on the non-contact parts?

Thanks,

His T&C cutter grinder could sharpen an involute gear cutter easily by grinding the cutting faces with a dish wheel. I don't believe it would be possible to grind one new from scratch, but I'll let him say yay or nay. I suppose it's possible with first dressing the form onto a wheel with a radius/angle dresser device, though a Godawful amount of work for something you can find all over eBay and as new from several suppliers.

F&D Tool of Three Rivers MA (not far from me) still makes their form relieved cutters in diametral pitch and in both 14-1/2º and 20º pressure angles. They range in price from about $94 to over $2800 (a big 8" 1 DP) so that's probably why you want to know if he can grind them.
