I wanted to expand a little on the process of extrating parts in the most usable state. Deconstructing a spotwelded car is a challange. Let's face it. The car you are working to collect parts from you are really destroying. You really have to to get the part you need in the most unmolested state.
I dont often drill out welds but this section and example where I thought it was the best choice. I moved away from Blair spot Weld Drills as they are hard to center and gauge the depth you are drilling. If you over do it you are thinning the part you are attmpting to repair.
I need the bulkhead panel as the one in Rocky's car was bowed at the top when the strut towers pulled inward. The vertcal panel was kinked and dented from maybe a spare tire?
Anyway there are alot of spotwelds securing the bracing to the wheelhouse. The outer spotwelds are small. I was able to clear most of them with an 1/8 drill bit. When the section is reinstalled I will tig the donor part in place and most likely the welds will appear to be spotwelds again. The inner welds holding the parts together are a bit larger. And the strut tower top on the wheel house side it heavier gauge. I used a step drill to increase the 1/8" holes to clear the spotweld.
The second step I used was to go to the back side and use my ball grinder the thin the metal making the part I am not saving thin and weak. I have a couple screwdrivers I ground into a chisels to split the two parts.
The outer section of spot welds on the brace were still held but easy to split. I also cut around the "Cap" on the wheelhouse side to separate the outer wheelhouse side from the Cap.
The Cap part or strut mount I also used my ball grinder on. Once I felt I have the mount weaked enough. I used my screwdriver chisel from the top opening and struck the cap lip around the opening. There were a few spots hold but after a couple hits the part popped out.
Again I will Tig these holes when reinstalling.
