Alternative Artillery Barrel Fabrication

I was about to ask how you cut the riflings in the barrel, but your last post says you used an MG barrel as your starting point. Is the twist rate compatable?

Sorry; wrong blank! My bad! I used the 30 cal MG barrel blank in another project [Broomhandle Mauser]. This was a 1 3/16" dia no-name blank from Numrich.

I'm not too fussy about twist; I reload, and tailor my loads to the individual weapon being used, for these special one-off projects. Pretty much whatever is available is 'good enough' for me.

Difficult to shoot pics and machine at the same time...and video would probably take longer than my digi-cam memory chip would allow...

Absolute genius IMHO!

If you end up hosting your photos over on CNCguns...

I can stash the pics on PhotoBucket & link them; I owe the guys at CNCGuns a thread like this one...but I can do two; not a biggie...

P.S. Make a second barrel & sell it and use the money to get you a broadband internet connection!

It's a long story, but my heavily wooded rural area does not have broadband support.
