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 decided to go with the ER70S6 , followed by case hardening . Turns out it is actually quite hard as-welded - might actually need to be tempered - so I skipped the case hardening . I'm waiting for a call back from the neighbor since I kinda melted a sharp corner and it's going to be a bitch to try to build up - this thing is only about 3/8" in diameter with a flat on one side . I can cut that bit off if taking off a sixteenth will be acceptable . Most of these nail guns have a depth setting so I'm thinking it won't be a problem to shorten it but I want to check with him to be sure .
