I also want to document the process if anyone here would be interested. Looking at a finished project and knowing that as much as possible was done by myself is just a happy experience (or maybe a prideful one) that's what's engaging to me, finding an issue and solving it creatively. The fun comes from the process, the problem solving. If I wanted to be lazy, I could just have the guy who built my Egyptian Maadi just do it for me. I was hoping someone on here had made their own tools as well. but that might not be the best way, which is why i was looking for input. I think a more specific question i meant to ask is: how do you go about forming the bucking bar to press the front trunnion rivets? my idea was making a sort of tennon on some steel bar and running it through the entirety of the receiver and pressing from the outside (grade 8 bolt head with a dimple formed to the shape of a rivet head, place that under the press, make sure the head of the rivet is tight to the receiver to make sure the tail forms on the inside of the trunnion). I have a set of 24" bolt cutters that I'm debating making my own rivet jaws out of, i found a guide on here, and it doesnt seem that hard (yes, i have plenty of experience working with metal) that or making a bar to press the tails. or it will bend over, and suck.That's what I'm asking advice on, there's not a huge amount of information available You have to have the rifle rock steady on a bench, and you have to hit the rivet square on every time. if your good, a quick and dirty way would be to take a flat punch and beat the head of the rivet down flat until it starts to compress. If you don't have, or don't want to buy the jig. Start out with the deeper buck, and work your way down to the shallower until you have a nice button with no flat. take it out of the jig, but a dimpled buck on the currently flat rivet head, put a dimpled buck on the round head of the opposite rivet head. Before it spreads/compresses out too far. If you want to form a dome, then the best way I've found is to start to compress your rivet (flat) until the rivet head starts to spread. If all you want is a flat side, and it looks like you might if you want the look of a Russian side folder rivet, then you just compress the rivet flat and your done. You can check the classifieds over there. 'Plinker' on used to sell a jig that works really well for that (that's what I use) but I don't know if he still sells it. The trick to pressing a through rivet is to have everything lined up just about perfect so that the side your trying to smash doesn't lean over one way or the other. sometimes they're a real pain in the ass. Sometimes they go easier than other times. You'll have to have the drill perfectly centered (AK-builder has a good tool for that) and you'll have to drill it just about all the way through before you can pound the rest of the rivet shank out. not necessarily cheapest) is to remove/drill out the rivet. I ended up drilling out all the long rivets that we did together and redit them myself, and they look much better. I took my time to come up with a better way to support the receiver, and did the rivet myself. Hard to describe, but basically, it could not have been any more off-center. When I got it out, the shaft of the rivet was beneath the side of the head. I drilled it out very carefully as to not mar the receiver or egg the holes. I ended up buying his tools and went to work this week. Not wanting to mess with it, I left the rivet. Needless to say the rivet looked horrible, but it held fast. Well his technique was not the best (he didn't follow the instructions) and of course the receiver kicked out under pressure. The guy who was helping me had never done that type before, and he couldn't support it securely. My first build was a Yugo with an bulged trunnion. The best way to fix it is to drill it and redo it. ![]()
