I seam to recall Lambert mentioning a while back that he wanted to put donkey dongs on all of his bench guns so he could work them with his poor old hands. I had to do one today and the angle plate was in the machine so I did it old school, the way the poor folk do it. It is a comercial handle and the thread is 5/16x24 To cut the stub you need either a Norseman or Milwaukee 5/8 x 1 inch annular cutter (trepan cutter). Both of these cut a 5/16 core. The setup is simple. Done in an angle plate use a small aluminum block to get the bolt handle square and a penny to protect the bolt finish from the machine setup clamping bar. I just eyeball the handle straight up and down and clamp it tight. Make sure you measure the bolt where the ball meets the handle before you clamp it in so that you can find the center of the handle from X and Y on your table. A lot of those handles are different measurements so measure the one you are cutting or it won't come out centered. Run your annular cutter at about 150 RPM with a full flood of water or you will burn it out. They generate a lot of heat USE A LOT OF WATER. You should be able to do about 30 handles with one cutter and they are easy to sharpen with a diamond hone. You can cut the threads with a die in an adapter under power or take it out and do it in a vise. Either way works fine. This can be done in a mill or medium weight drill press.
Add Note: I remove the 5/8 cutter and installed a 1/2 inch annular cutter which cuts a .280 core to cut a .100 length area for the die to start on. I don't bother to square off the end but if you wanted to you could just drop in an endmill and run a pass over it. Now that I'm thinking of it I suppose you could just run the X or Y over and take a light cut with the annular cutter to square it. DOH!
Add Note: For those who were confused by the setup and the clamping and emailed me, see the 4th picture.
