i'm trying to figure out how to make some very small (think small
servo-sized) involute spur gears. i have a taig CNC with rotary table
and a sherline lathe. ...and i'm not averse to purchasing some
the smallest / most complex spur gears i'd like to make are 90
diametral pitch (120 DP would be great), and perhaps 90 or more teeth.
(pressure angle is not critical to me: 20 or 14 1/2 degree PA seem
i've tried to find involute gear cutters, but i can't find anything
greater than 60 DP.
i'd try to find a service provider to help...but since i'll probably
want to go through several iterations to find the right DP and tooth
count, it would probably get expensive quickly. (plus, it'd be fun to
be able to make these on my equipment at home.) ...or am i crazy to try
to do this type of thing at home?
any help would be greatly appreciated...
