this is for the people who dont want to drag out their press to use hydraulic style jigs....
in talking to my good buddy Pryotex, we were discussing making a small compact rivet squeezer to use on both AK's and PSL's... after we kicked some stuff around & had a couple ideas here's what it ended up being..
some scrap 3" channel
1 grade 8 3/8x1.25" bolt fine thread
1 grade 8 3/8 fine thread nut
1 10x32 button head screw
heres how you do it.
take the scrap c channel and cut 2 pcs off of it... mine are 2" long x 3" wide..
pic #1 here.
weld them together on top of each other and find your center... then drill your pilot hole thru both sides to make sure everything lines up.... (my pilot hole was the same size as the #10 screw for the bottom pivot point.)
next drill out your top hole to the 3/8" size. center your bolt/nut combo in the hole and tighten them down so they dont move...
then make ugly welds around the nut like i did..
pic #3 here.
only thing else to do was to take a ball nose bit for the rotozip or endmill and make your nice round bowl in the end of the bolt and the head of the #10 screw... this will let you get round rivets instead of flat.
now check your alignment.. here it is on the rear trunny of a PSL in both the rear and forward rivet locations.

this actually worked way better than i thought it would and the tensile strength on the grade 8 bolt/nut set up is way way overkill for these rivets.
this one is ugly/cheap but it proved the idea and execution was solid. so now i'll make another one out of some good non rusted flat steel and then probably Karma this one out.
the only thing i found not to my liking was for the PSL FRONT LONG RIVET.... the 3" channel is a bit too tight for that and i'll make my next one out of 4" channel or a 4" piece of plate.
thanks for looking!
this is originally hosted/posted at WG... so the pix didnt insert into place here the same size.... they are also at the bottom & still in order to where they go.
