By Jove I think I've got it: AK rivet location P/N Part description cost rear trunnion "rivets" 8893K26 11/64 steel rod, 6' 2.51 handguard/front trunion 97300A105 300qty 5/32 rivets 7.76 Center support rivet 97300A675 75qty 3/16 rivets 5.54 Center support bushing 9220K32 steel tube 6' 8.21 Total $24.02+shipping less than what I would pay for the three rivet sets I need, plus I'll have plenty of leftovers... for the rear trunnion, my plan is to crush the rod with two steel plates that have hemi-spheres. I'm pretty sure I can do that with my bench vice. what say you? |
from mcmaster:
that works out to ~1000-2000 lbs to yield an 11/64 inch rod...maybe I'll use my 12 ton press...  of course it could be brittle then there's this: 5227T13 ~60000 psi, but still probably to hard... ETA or this: 8984K95 ~35000 psi, but 5/32". What is the diameter of the rear trunion rivets supposed to be? the other option I see is grinding down a 3/16" rivet, but that seems tedious. |
