Anyone making their own wooden knobs on a lathe?

In that case, no. Would be easy, though.
Those look nice!

Just these...I made all wood ones but these work better with rest of the hardware.

More slick stuff. Nice knobs! I like how the wood extends through the side. Is the wood one piece?

Yes...one piece...epoxied in and then cut flush along with the final aluminum surfaces.

Nice job Filippo!

Have you ever made bell knobs like these?:

Looks like it would require some kind of duplicating setup to be ultra consistent.

I'm wondering if anyone's made anything like that? I don't really want to spend $400 for something decent, nor $200 for something flimsy and cheap.

doesn't the metal get blazing hot during milling, and risk burning the wood core...?

You generally want to use a coolant when cutting aluminum. I get these to an "almost done" state on a metal cutting machine and do the final cut on another. After the wood inserts are glued the last cut takes off .005" from the aluminum surfaces and the wood cuts flush to that. There's no heat at all generated in this operation.

The hardest part of this was making a tool that would hold these when it came time to polish them. I made a little fixture that mounts in a drill. The knob mounts on the end using small allen screws to spread a split post. Then I can go to a hard fiber wheel on a grinder...and rotate the knob with the drill as the wheel brings the wood and aluminum to a high polish in a half a minute. Ez peazy.

Stuart that is some beautiful work! I can't imagine taking the huge amount of time to make a complete instrument then to only have to take so much time on embellishments... Kudos to everyone in this thread who does.
