If anyone else wants to run the program, let me know and I'll post where to get GWBASIC, how to get your program in, and a few things that needed changed to work with this version of GWBASIC.
We still don't know the type and RC hardness of these bolts/trunnions. If someone had a RC tester we could find out at least that much. The numbers below are based on a main bolt body of .635. Since the AK bolts aren't the same as a bolt action, it's a little hard to get a good measurement. The AMD bolt was the best to get this measurement from.
Also we are just using that the AK bolt has 2 of the small lugs. It would be hard to get a good number with the cut out for the extractor on the large lug. Since the large lug is longer it should be stronger according to Lilja's program.
I'm not saying that any of the numbers listed below should be taken that it is safe to build that type of rifle. We are using numbers taken off the net and Dan's program. I'm not saying anything bad about Dan, but I'm not an engineer and I can't look at his formulas to say that yes they are correct. We are assuming that everything is correct, that the yield pressure of the steel is 100,000psi, and the ammo is loaded to SAAMI max specs.
