Message: <blockquote data-quote="n8thegr8" data-source="post: 2270551" data-attributes="member: 6349">I decided to have another go at it myself. I demilled the screwed up front trunnion, bought a new front trunnion, and riveted that in. Unfortunately, I sold my Toth bolt cutter rivet tool, so in order to rivet the new trunnion in, I decided to just make my own ($15 for the boltcutters and an hour of grinding, vs an additional $70 for the Toth jaws). I just got after it with a bench grinder, and this is what I came up with:<img src="https://www.okshooters.com/data/MetaMirrorCache/img.tapatalk.com_d_13_08_19_ranevyry.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />I made a bucking bar for the rivet head out of some mild steel, making the dimple with a 5/16" ball nose end mill. I tried to make the dimple in the jaw itself, but the steel is way too hard (I couldn't even center-punch it). You just cut the dimple until the rivet head barely sits above the surface (you don't want to go all the way, otherwise you'll be pressing against the receiver instead of the rivet head). Polishing the dimple is a good idea so you don't mar the rivet head.Now I just need to get a new barrel...</blockquote>
