I will try and answer some of your questions.

"So if I understand correctly you reverse engineered via 3d scanning a model 21 action, imported those files into BobCad, tweaked them into a parametric model, and am using the CAM capability in BobCad to generate and post the G code which your trying to cleanup?"

That is basically correct in that I reverse engineered a Win. 21 but I did make some modifications creating a full 3-D cad file of all the components. We then import portions of those files into Bobcad and generate the G code read by the CNC machine.

"Do you or the owner of the mill know GCode? or are you tweaking the cam generation process to fix tool path issues? Gcode is pretty simple, and if you have any programming experience you can learn the basics pretty easily:"

Yes, G Code is routinely used but there are still anomolies lying deep in the cad code that must be determined during the validation process. You cannot simply load the program, index the item, and expect to have a a perfect copy. You really need to run the code line by line slowly. Remember all the real work is in creating the tooling, fixtures, and debugging the code. Once that is done the machine really will do its job.

"If I have that somewhat correct, what mill and controller?"

HAAS mill and integral controller.

Good luck on your project.

Doublerifle Jack,

Yes, I have seen the Galazan DRs although it was year before last at the Las Vegas gun show where I looked at the heavy caliber version and I didn't study it well. I wish I had now. I know they were going toward a 416 and a 577. I also knew I would not be approaching those. They substantially beefed up the receiver in the area where it is obvious that it is weakest. I agree that it is not especially pretty. They make a 45-70 on the flat side version of the 21 receiver. I think that is really pushing the limits. I will go with the older version with the boss for support. In anything above 45-70 in pressure I will increase the mass of the boss across and above. In addition I will add about 1/4" behind the strikers to really support the bushing and firing pins. Then I will fire a lot of proof loads with careful measurements before and after to ensure I am well within the elastic limits of the receiver. Thank you all for your help.-----Bill
