Having worked out the pitch of the broken drive gears (120), and
having looked on a couple of web sites _and_ contacted someone
at Boston Gear, it's looking grim.
According to the e-mail I got back, Boston Gear doesn't carry anything
finer than a pitch of 64. When I asked who did carry such gears, the
answer was: "I am not familiar with any company that makes miniature
gearing." :-(
My goal all along has been to find a company that has a bag of these
on the shelf. I had no idea it was such an unusual item. I don't
relish the idea of fabrication, but maybe that's what we're facing.
Rather than machining each gear, I wonder how hard it would be to
make an extrusion die to pump out a long gear and cut it into 5/32"
slices?
