Drilling and hammering on vintage knuckleheads can be a traumatizing experience. Don't fuck it up. Dad made a special pin(rivet) to lock the intake flange. We peened it from the inside, smoothed it out and formed it to a stock-like appearance. Now the flange is tight and secure. PJ-1 Satin Black and it's ready for the valves. Late Model Knucklehead: The last one, and the best one.
I usually tap a tapered plug into the port and set the rivet from the outside.. Thanks for posting your method.........
ReplyDeleteI think that's the factory-way to do it, like you did it. I'm backwards ! The only rivets I could find were way to hard, or too soft aluminum, so we made some that peened pretty solid.
