Jack -

I left the flange a bit oversize. The most a Luger barrel can be off is .050"...(20 threads per inch = .050" x 20). I read in another thread here that 1/8 of a turn is about right for torqueing the barrel down. So the most the barrel can be off is 7/8 of a turn... or .044"...

My flange is at .170"...Rick W quoted me .135" for the flange on his artillery barrel...So I have .035" to play with...I'll screw the barrel on and torque it down three times, then figure out how much I need to thin the flange from there...(It's easier to do than describe)...

I'll take pics...Right now, I'm still milling the front sight to size...I've mounted my barrel in my rotary indexing head and milled the front sight band and flange down, 4�º at a time...and milled the front & sides of the front sight flat with the barrel base...

This barrel is easier than most I've done...It has a convenient flat (rear sight base) for spirit leveling...that's what I'll use to level the barrel in the receiver.
