Question. For forming a .327 diameter, .140 high round head on a 3/16" diameter rivet, what length should I have extending beyond the surface ? I purchased from McMaster Carr: #97300a677 rivets 2" long 3/16" diam head is .327 diam, 0.140 high. The 2" length is more than needed for use in the rear trunion....but I need to know just what length to cut it to , to leave enough material to form a nice round head when squishing the rivet. |

I don't know the exact dimensions, but I have found that leaving 3/16" of rivet extending past the receiver will leave just the right amount of material to form a round head exactly like the other side of a standard rear trunnion rivet. However, I used the correct metric rivots that are slightly smaller than the 3/16" rivets you want to use. I believe you will have to drill out the trunnion holes to fit the larger rivets. I have found that is is better to start the head formation with light taps from a hammer. Then I use a small piece of metal with a divot in the press to finish the head. I don't have a plinker's jig... |
