I was using a clamp with the hole for the pin. But I neglected to dimple the moving flat surface on the end of the screw, so the pin bent when installing. I was thinking on either brazing that part solid, and actually drilling a hole to accommodate the pin for say 1/4", so that it is supported. This would eliminate the off centering, and lessen the chance of bending. The pin isn't put in flush anyway. The hole would be drilled so that the pin fits freely. Are the pins a standard size? I also thought about removing the 'wobbly' bit, and just drilling the centre of the screw part.

However, during the description of the tool used to remove the pedal pivot pin, several critical items were left out. For example, how big do you make the hole.what size drill bit is required? 3/8" ?? How can anyone get a good ,FLAT< drilling surface when trying to drill through the "top part of the clamp body"? Mr. Nereson, RPT of Denver uses this tool, and it sounds like a great idea. But, could I get some more details, please? Brian P. Doepke, M.Mus.Ed.,RPT A.A.A.
