I am going to be riveting a new drive chain sprocket on the clutch drum of my 1925 Harley JD and was wondering if there were any 'rules of thumb' on how far the rivet should protrude from the surface. The hole is also a 30 degree countersink. Experience years ago taught me that too short of a rivet is not good but too long of one is not either. I am going to have to do it free hand because my rivet set does not have enough throat - also heat or no heat?
All help appreciated. Jerry
