In my attempts to try using a ball bearing the straighten these air horns, I have discovered a major problem. This socket is exactly the right size to remove dents from the straight part of the air horn. It just fits. Its outside dia. is about 0.800. The nearest fraction would be 51/64th. (0.796). A bearing that size would probably straighten the bend in the air horn. I would also need a couple smaller bearings to work up to the 51/64th bearing. The problem is finding a 51/64th (0.796 or 20.23mm) ball bearing. I have spent some time looking. I thought I had found one but my head flipped the 15 around to 51 and it was awhile before I realized it wasn’t what I thought it was. Don’t know what I would have done with 300 of them.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
