Re: Barrel threads
I had just read through that same chapter today as well, funny you should post this, as I was wondering about it now myself. [img]images/icons/smile.gif[/img] I havn't checked out the link to the other thread yet but will take a peak. I did find his sketch on pg 115 to be reversed though, the receiver face would have to be to the left, would it not?
With that small of contact area I wonder how many times the barrel could be switched and not gaul and ruin either one, he was using CM I believe? It seems like what would work best is a progressive rate thread pitch starting finer and going coarser at the barrel shoulder. Can you cut a progressive thread like that on a lathe?
