Guys, my apologies for not going into specific details of the repair I had considered. I felt it unnecessary to type THAT much. I did consider a drill hole at the terminus of the crack to eliminate the stress riser. Milling/welding would have been preceded by annealing and followed by a proper heat treatment and hardness test then followed by remote firing and inspection... nothing to loose as the receiver was junk to me otherwise. This wasn't going to be a quick 'grind and burn'. It really bothers me when people refer to welding as 'burning in'...
My 'inner scientist' forces me to do these things... an I have the resources available...
On a far more important note, I just dyed the Turner sling a nice 'cordovan' to look more period.
I do welcome your thoughts and insight. It's great to be able to tap into the wealth of knowledge here.
Cheers!
