granute: Please note that F.A. indicated they do have drawings available separately for the Borchardt. You may wish to contact them.
Tentman: ASSRA offers the old Tools Int'l drawings to members as part of their Archives service. I obtained copies (only $10 for each action) for all but the Sharps, and I can say they are well done.
The process you describe (CAD + CNC + EDM) is just what Steve Earle has done to make his Wesson kits. Please read the
(You need to Login or Register to view media files and links) in the SSRJ feature of the month section of this web site. If you reach critical mass for your project, you might contact him regarding having the work done. I believe I read (1) his action, in the white, is about $1200, and (2) he made about 35 for the first run, so you are looking at that price minimum, per action.
As for me and my project, it isn't complete even in my mind's eye, and I am not ready to commit to a design. I'd be happy to discuss a new single shot design, and perhaps I'd agree to be a purchaser of the one you organise. If you wish to explore this, start a new thread in this section and see what we all come up with. I have to believe it will be difficult to get an original design "by committee" together, but perhaps one of the classics could be done. I think I recall reading Earle was to begin work on another kit, so you might ask him what he's up to.
