44-100?

Kurt,

do you know how to make a spring loaded dead center ? when I worked in shops all those years ago, we made these to help in situations such as this.

the spring keeps tension on it but not so much pressure as to cause binding.

my suggestion would be to get some 4140 or 4340 and drill and ream a practice chamber or 2 or 3 to work on before actually getting into the barrel for real

you would need a fan behind you and don't breath it much or get on your hands, but a mixture of trichlorethylene and cutting oil makes a good cutting fluid, similar to the old old formulations of tap magic, before they found out some of the chemicals in tap magic caused cancer. the chips come out like paper

it is going to cut on the taper area of the chamber also a little because of changing the diameter of where the angle starts at

this company has spring loaded live centers

I am not sure of how stiff the spring is, but it will give you an idea
