In order to clean up some of the dents in the "H" part of the apron, I needed to remove the forward section that has the engine seal lip welded to it. I decided to try my new spot weld cutter on it. I've never used one before but I can't ruin a peice that is already trashed right? My first few attempts did not go so well. The cutter did not want to stay in place very well at all. So the holes were not cut very clean.
So I figured if I drill a little dimple in the center of the spot weld this will help keep the cutter in the right place. Wow, what a difference. This also had the added benefit of letting me know when the weld was fully cut. The trick is to drill the dimple deep enough to go through the top piece of metal but not all the way through. That way the spring loaded tip on the cutter puts enough pressure on the back piece of metal to make a "pop" noise when the weld is cut out.
If you have not seen a spot weld cutter, here is a picture of one. They are very cheap and worth getting 5 or 6 to have around if you plan on doing any body work at all that requires removing panels. I got mine at Harbor Freight. 
Here is the back side of the skin. with the engine bay seal holder removed. I still need to cut the "H" out, but I will wait until I get the new apron before I do that.
