Can someone make me some mechanics for a music box?

Unless you are REALLY GOOD with mechanical fabrication skills at this level, you are better searching for a company that will make you what you need. They exist. They have mechanisms built for all size applications and installations, and frankly - it is only the drum ( the turning cylinder with appropriate pegs) that has to be custom made - and THEY are set up to do it. Many years ago, I think I saw a link thru Klockit - not sure.

Thanks for your help!!! Much appreciated!!!

This design has all the tools and info to make a custom music cylinder:

The whole thing is cranked rather than wind up but you can add a drive mechanism from something else, or just use the cylinder and comb in another mechanism.


Or a common type that work from paper strips. You could use one of those to get the music perfect then wrap the paper around a drum & set the pin positions through the holes.

eg. on a "bid drum" design such as this:
