On V Kay until the 2nd of September so i went to the shop to work on the ML. Made a new breech plug and threaded the barrel. My camera died so here are the barrel drilling pics and how i did it. There could be a zillion ways to do what i did but this was the easiest for me....Bob
Pic 1 1/2 pin in the bore to line the barrel up
Pic 2 jig holding the barrel to the t slot cross slide.
Pic 3 Using my steady rest to hold up the end of the barrel. Yes you can hold an octagon just don't turn the machine on. The barrel will slide L-R as i am drilling and tapping it just won't turn.
Pic 4 Drilling out the old 4 start metric threads with a 4 flute 5/8" drill.
Pic 5 Drilling 11/16
Pic 6 Tapping 3/4-16
