I thought I would start working on removing the rear quarter on the passenger side of the Chevelle. A previous owner cut it across the top and did not weld things back together. As well, the bottom (behind the rear tire) was rotted out. Finally, just behind the door the panel had a decent size crack.
The question I had was how to remove the spot welds. I've tried the fancy spot weld cutting bits and was underwhelmed with them. They broke often and I have quite a few spot welds to cut through.
Looking at:
I have the sander / grinder he is using (yes, I realize that the presenter leaves much to be desired). I tried that and it worked, but it seemed like it was taking a long time.
I then tried use the plasma cutter to remove the spot welds, as shown at:
So far, the plasma cutter has done an excellent job. It does take a steady hand, though. I did put a couple of pin holes in the base panel when my attention was not fully on the work, but those will easily fill with the TIG. If I simply go along the edge of the two panels pointing outward, then bringing it into the panel, I can do it without any base metal damage (even less than what the video shows).
