I am intrigued by the burning method. I would like to know more about that. Thanks!

Would a spoon bit work without a lathe? Those gimlets work by hand, maybe in a slow speed drill too...

So the cupping is made after twisting... I thought that i need to make it before the twist. The tip is "screw like" to enter the wood just from rotating, without too much presure, do you think that i could make that threads with a file or something similar?

Hello,

I want to make a romanian caval (http://www.eliznik.org.uk/RomaniaMusic/cavals.htm) from plum wood.

I have read that those kind of gimlets are the best chioice for that because they follow the grain of the wood. I have a old one, but the diameter is too small, i need a bore diameter of about 17 mm.

Does any of you have a ideea about how could i make such a gimlet? I can't figure out how i need to form the metal before turning it in a spiral. If some of you have experience with those kind of thing and can explain it to me that would be great. Some images would be great also.

Thanks!
