Tip of the Week: 7/8/2012 Better Pins

A common parts failure–especially in high power applications–is a drive pin. Either the pin in a universal joint fails or the actual drive pin in the axle. If you’re repeatedly bending pins, try a high quality drill bit. You can even find high strength drill bit blanks, but sacrificing a drill bit will do just fine. You can cut the drill bit to length (use the smooth shank end, of course) with a rotary tool (wear proper eye protection) or hit up a machine shop. A high quality drill bit may cost a little, but it will often be the best solution to a frustrating problem.
