Started on a few spot welds this afternoon after fighting my spot weld cutter. The pilot tip needed a little sharpening so I did that, but in the process I lost the spring somehow. Luckily I have 2, so I tried to use the second one but the pilot hole is wallowed out. I then swapped the spring into the first one, made a couple cuts before the pilot stuck. Pulled it apart again to clean the chips from the bore and went back at it. This happened a couple times - I think I spent more time dealing with the cutter than I did working on the spot welds. But when I did work on the spot welds, the dimple I punched into the center didn't hold the pilot well enough and the cutter would walk. I was so frustrated by then that I just gave up for the night. When I get back out there I'll start by drilling some pilot holes, hopefully that will do the trick!
