Aluminum Sieria

[Boz]

I want to try my hand at making an Aluminum pen as shown in Fangar's tutorial in the library. I want to start with making a Sieria and was wondering what bit I could bore out the centers and leave the correct hole dia. so that I do not need to glue in the brass tube.

Measure the inside of a Sierra brass tube.

Lin.

I agree with Lin. If I'm not mistaken, it is going to be real close to 6mm.

Test an "O". I think that is what I used.
