Hi Kirk, One of the main reasons I want to try to generate gears and, particularly, pinions is the great problem I have in trying to make working pinion cutters small enough for the watches I work on. I could get cutters made but, as you have said, a different one is required for each

We should talk one day, I work with Chris Lowe at Richards of Burton, and have made a cnc to cut gears here, I still use a Safag for the really small stuff though. I want to do profile work for escape wheels, verge and normal. Dave Caroline archivist on the #emc IRC channel on freenode

Alan Thanks for reply. I am using steppers, so do I add my read and writes to the servo thread or the base thread? My .hal file still has all the original configuration lines in, which I know work... will it run once I make these changes or is there still more to do? Aaron -

Hello all, Is Galesburg still floating? No, that's not a joke. I have a real concern and hope all is well in Galesburg. With all the rain and bad weather you have had, will there still be an EMC Fest 2008? Thank you Dale

snip Another thought comes to mind, could wire EDM be used to cut very small gears and pinions? /snip I know I've seen someone take a rotary tool similar to a Proxon (beefy dremel type) and true out the spindle and cut his collets using EDM and they were fairly small. So I don't see why doing

Idea is ok but Dremel stuff is in no way suitable for the scales that Ian Wright or us need when cutting watch pinion sizes. The positional accuracy needed to get a good form to the result is also a problem. Involute form is easy as a hobbing action and generation is possible but not for cycloidal
