Well, first post here, so don't beat me up too badly. No formal machining training, but I manage to get things done. Have the use of an old, but decent and tight manual lathe and a milling machine.
I want to convert a Lee full length brass cartridge sizing die into a "body die" that sizes the body of the brass only and leaves the neck basically untouched. So I would like to machine the neck portion of the die out to the size of a fired brass case, which in this case would be .347". That way when the fired brass enters the die, it will be centered by the neck, but only the brass body itself will be re-sized,
How to do it?? Reamer? HSS? (doubtful) Cobalt? Carbide?
Or attempt to lap it out??
Thanks in advance for any help!
