Another technique for confirming correct LP rivet grip length.....
The witness lines on the rivet can be used to confirm proper size.
The mark at the shorter position is the minimum grip and the other mark is the maximum grip. So if you insert a rivet and the max grip line is visible but the minimum line is not, the rivet is of acceptable size at that location
