i decided to install a new 6 inch on my DA Reichsrevolver. the octagon flats were excactly 3/4 inch. being lazy. I cut notch in the box end to go over
the front sight. then i kept cutting for about 3 inches. i wraped i layer of elevtrical tape and i had to drive a small hacksaw cut to open the box
end to slide the wrench on over the tape. i then did the same thing to aluminum angle in the vice to clamp the frame. i hade to use purple force
with a 2 ft extntion to loosen the barrel. this left 3 little marks on the edge of the flats. 20-20 hindsight, i should of used aluminum frm a beer can.
now the thread pitch gauge . 1.4 MM pitch was the closeses i could get but it was,nt right. got the sae pitch gauge and 18 tpi was bang on. WTF???
i was standing there and the light came on . 3/8 pipe thread is 18 tpi. i grabed a 3/8 pipe tap and it screwed right in un till i bottomed out.
pipe taps are npt. T stands for taper. they make 3/8 nps. s stands for straight. any how i have the barrel fitted with 3 thou cylinder gap. now i hav to make a front sight/
i forgot to mention . before i turned the barrel of , i had clamped a pair of vice grips close to the box end of the wrench. this realy gripped the barrel tite.
the notch in the wrench is to allow to go over the front sight.
