well guys I have been plugging a way at the builds and I guess you could say I haven't gotten much more done with all the fourth stuff going on . I do have the long rivet jig built and it looks good. I have gotten a lot of good advice from all of you guys and I hope you can help me with a new issue.... I am making my own set of rivet squeezers( toth copy) for the short front trunnion rivits and I was wondering about overall rivet length that achieves the correct size shop head when the rivet is squeezed .I want my squeezer to come out right when I finish grinding the jaws. I only have rudimentary grinding done to the jaws- if I knew what the tool was measuring when it was fully closed that should be what the rivet measures after squeezing? has any body seen a good diagram with dimensions out there for this tool? any ideas on making the tool or good diagrams would be greatly appreciated. also any good suggestions for the swellneck rivet head shape for the backer plates? I ve made a few but you guys have got to have a few tricks for that I bet. thanks again guys.
