Banjo Build
S. Heslop:
Haven't done much today in the garage. But I did test that burr idea.
Seems to work fine. I tried it first with aluminium and it clogged the burr in seconds, but I then remembered I had a square bit of brass (about 1/2" wide). Depth of cut is about 4mm. The cut was made fairly fast and the brass heated up a bit but not to the point that it hurt to touch. So I think this idea seems fairly viable for brass at least. Possibly cast iron too, and anything where the chips aren't gonna clog the burr.
The only concern I have is the brass chips falling into the router below. I might try cover the vents (will still have to allow airflow).
While waiting for a chance to buy the brass required I'll probably make the hooks and nuts.

I've been following this with interest, I've made a Ukelele and a rough Guitar. I have an ambition to make a proper Guitar. What is the skin made from?

TCT router bits work well on aluminum spray the cutter with wd40 to stop a build up .

Mylar plastic as far as I know. Some folk like to use calf or goat skin for an 'authentic old time tone' but I think that's silly. Skin heads tend to change tension with humidity changes and can sometimes burst from it, and they're awkward to fit from what i've read. I did consider getting some skin for that rim with the 50 hooks, since there wasn't alot of space between the rim and the hooks to fit the rim of the head. I ended up filing notches into it to get it to fit.
I also tried looking up using plastic sheet as a head material but couldn't find much information on it other than a few failure stories (mostly with it stretching over time until eventually breaking). Didn't fancy experimenting.

I'm concerned this router table won't be at all strong enough for any serious cutting forces. I figured that since I can control a burr with my arms no problem it won't have too much force to deal with.

I have cut ally with a circular saw a planer and a router , no table or bench on site you don't have to cut it all out in one cut .
