I have here a L Frame already stripped waiting for a barrel.First of all when you take the original barrel off,There is a ridge left on the front of the frame,If you are installing the same barrel or a factory barrel you do not have to remove the ridge.In my case here I'm installing a Bull barrel and the ridge must come off as it will interfere with the larger diameter shoulder of the bull barrel.What you do is remove just enough to take the ridge off,It must be done perfectly straight or the barrel will not seat flush.Even a couple of thou can put stress on the barrel and frame.Pic 1 is the frame(Sorry about the bad pics)
Pic 2 is the Front of the frame
Pic 3 The Frame Wrench
Pic 4 Is the barrel 1/8 before final torque
Pic 5 What it looks like in the Wrench.
I scribe a line on the barrel at 12 o'clock as you can see in the next pic.
That line is for top dead center when I torque the barrel onto the frame.Everyone does it different but I measure the top of the frame and get the center of the frame,99% of the time the screw hole for the rear sight is spot on.The next pic is the barrel installed onto the frame.
Tomorrow I'll adjust the B/C Gap,Cut the forcing cone...
