Ok, so I want to drill a hole in the center of either an 84 tooth gear or 30 tooth sprocket so the axles spin through them like a high strength gear’s plastic “free spinning” insert. I know team 323z already did this to an 84 tooth gear (Om-Nom V2.0, at least), but I was experimenting with a piece of wood and various drill bits and I couldn’t make any hole that fit nicely. There was either not enough space or too much “slop,” with the axle shifting.
This question goes out to everybody
Is there a preferred way to drill axle or regular screw-sized holes into gears or lexan? Should I use a hand drill or my magnificent drill press? AND, what size bit would you recommend?
