I was talking about Marks procedure & how he explained it to me. How Fred or Dave does it & how their machine is set up, I have no idea. I am sure there are Lots of variations of machines to make stocks on, as people have been making & duplicating stocks for ? 30 years. (I am sure someone will correct me on this as well & say it was 27yrs, 3 mo & 13 days, ? minutes & ? seconds......)
Maybe it depends on what you are requiring.. A EXACT finished stock or a stock for YOU to build a rifle from.
Myself, I have never asked for a Exact Duplication, as I want to build the rifle, not just assemble a rifle such as a GPR. What I have required was a rough shape buttshape, barrel inlet, RR hole drilled.
Fred has made several rough stock shapes & barrel inlets for me, always did a wonderful job, but I didn't ask of the detail of how he did it. to the best of my knowledge, Dave bought all of Freds patterns & machine, if I understand it correctly. Maybe he is doing it the same way, maybe not.
All I know of it how Mark told me he did the ones I have asked for, and the patterns I have used to have stocks made by him. He uses the pattern to rough it out, then does the barrel inlet of the barrel I sent, then does the RR groove & then the RR hole. He did what I have asked, and has done a wonderful job for me as well.
Maybe I have misunderstood all he told me. :idunno: and if so, I apologize for any misinformation I have passed on.
Best answer I can give is call them each and ask them personally, then you have it from the horses mouth.
