concave cut?
 

hey guys, new at this obviously, so thanks up-front!
how do you cut the concave head on a popper or little neck? can't say i got the slightest clue!

Ball rasp, mounted on a drill press.

or you could take an old spade bit and round it a little with the grinder, if you have any of those laying around

Or just use a spade bit and drill a hole for the cup but don't worry that it is not rounded. It will still spit water. Do your drilling before you cut any face angle.

i angle cut on the miter box, then i concave it with a dremil

Ball rasp or spade is correct. I will help you w/ the spade modification if you need it.

I've done the ball rasp thing and that is not pleasant. In prior posts guys have talked about a carbide spiked rasp (looks sorta like a dandelion) ......a "cutzall" maybe (?) that supposedly will do it without burning or catching.

First time I read about it I asked Flap to cut mine, since he was the closest Klutzall I could think of, be he just got mad and told me to go search again.

I asked this question a month or so ago and picked up one of those ball rasps. Well, it drew blood the first time I tried it but I think I got the technique now. You have to hold this in you hands while you work it in your drill press. Don't push too hard, it will run off the side and CUDZULL your friggin hand up in a nanosecond.
If your skin touches this thing, it will start taking lots of small chunks out of it in a hurry. Be careful, it is agressive. That said, it does a nice job on the wood, once you clean the blood off. I need to get a larger set of balls now. (both meanings)

Saves you from coloring the mouth red though.

excellent info gentlemen, much appreciated! turning wood is great, all the other stuff is aaaaaaaa, where it all starts to get hairy! thanks again.

The 2nd ops. can be fun if you set uo properly to do them. The only non fixtured operation I do is cupping the face of a popper. When you cut the face of the plug at an angle you create a shape that is not round. I do my cupping by hand so I can "fit" the cup to the shape. It's slow and most guys are not that patient but it looks good!
