Tinker,

Your answer makes me glad I ask you. I guess I was asking "how you do you fly a plane" :^) What I'd like or love would be the ablility to weld the joint at the bbls and monoblock and be able to draw-file down the joint to invisible. Also, to leave a beveled edge on the breech end of the bbls. to weld up and dress down so the seems at the breeh face would be as close to invisible as possible and not worry about damaging the chamber or burning out into the sideclips or the excessive heat damaging any of the joints in the monoblock.
one monoblock had a couple of deep but very small pits we had to leave because I was afraid he would burn a larger place trying to fill them.
