After letting the pushrods dry for 24 hours, I was ready to rivet them. The large pushrods use pull rivets (6) on each end. Those went really well as expected...
The smaller diameter pushrods ends didn't go so well. I tried to squeeze the first set and it turned out terribly! I was going to drill those out - and went to the gun and bucking bar to rivet the others. One set came out really well, but the other end didn't. I can probably drill it out but it appears as though some of the pushrod was damaged, so I will have to see. If it's iffy, I will just reorder parts and maybe weld them (get someone to weld them) as that is an acceptable method per the plans.
