      My neighbor has asked me to build up a worn spot on the drive pin of   
   his framing nailer . I'm not sure what model it is . The pin has wear on   
   the flat side at the tip , and it appears to be from sliding against the   
   head of the next nail in line . I'm considering using SS for better   
   abrasion resistance . The pin is not particularly hard , can be marked   
   with a file , but "mushrooming" in the repaired area is also a   
   consideration . Replacement pins are available ...

   I thought the abrasion and galling resistance of stainless was worse than   
   carbon steel. Since I don't have the equipment to measure the hardness of   
   worn small parts or shop-made substitutes I try to replace them. My   
   Scleroscope clearly doesn't read correctly on small pieces like HSS lathe   
   bits, even if clamped in the milling vise. It seems right on large ones.
