Another rather eventful day. I happen to have a large quantity of half round head rivets but with some small modified press bits and lots of hydraulic power
I can change the head to any shape I want. the top of the intake covers have thin flat tops and the sides are thin mushroom style. As you can see I just put the rivet in a shank sized hole die, set my pressing depth and press away. I could probably do 2-300 per hour if need be. Then I cut them to the required length.
