So since the dust has settled a bit, I thought I'd shoot a few shots of what the hubbub was all about.
So this is the passenger side inner drop panel, still attached at this point to a section of the rear curve of the outer wheel house as well as being attached to a reminant of outer skin from the rear lower quarter panel. Laid out in front of it are my ball pein hammer and Steck panel splitter. The splitter got a serious work out on this job and will be the recipient of some axe file work to re-edge its chisel point. Closer in the foreground to the right of the panel are my I-R air drill with a spot weld cutter loaded into the chuck and my Evercraft air drill fitted with a 3M XLT paint/rust stripper wheel on a mandrel. The 3M wheel is great for rust/crud/paint/undercoat removal. The little squeeze bottle in the middle is air tool oil.
Just a quick close up of the hammer and splitter. You can see the mushroom effect on the end of the splitter from having to deal with all those factory spot welds after they had been "cut" free.
For cutting spot welds, I have two options for the type of spot weld cutter that I can use. The one in the air drill comes with a spring loaded point that indexes into a center punch dimple that you create using a center punch and a hammer. On steady stable surfaces, that dimple is easy to make; on a springy, loose, recalcitrant body panel that is fighting back, the results are highly sub-optimal and repetitive strikes mostly useless. Which is where, the cutter shown above comes in. Instead of the point, it has a drill bit center that will drill a pilot hole and then act as guide for the cutter to follow. Major issue with them is that the bit is fragile and they break, and break, and break, and .............. yeah. So in this case, where the point kept bouncing and deflecting off the weld, I ended up using the drill tipped shank by itself to get a hole just deep enough that the point would sit down in and stay on track. As you can see from the close up, the cutters are replaceable which is a good thing because those factory welds beat them up and chew up the tooth points to where they will not cut at all, just sort of float over the metal.
What's left of the panel lip that mates up to the outer wheel house just behind the rear wheel, along with s small flap of metal that used to be part of that wheel house. All this came as part of a complete rear quarter section that included the trunk lid and valence. The donor was an 83 Monte that also gave up a door which, post rehabilitative surgery, now resides on the passenger side hinges of my ride. The previous door went to the table for a total replacement of the lower shelf and flange; it was all gone, totally rotted out and mostly memory. With it I got as far as tacking the replacement metal in place but the other shell was already done and ready to use so it got hung. Still needs to be skinned and there is a brand new EPT coated skin waiting in its box for me to do that not so little thing. (Need to find a child's metal legged swing set and do some editing for size and use.......)
From previous experience I knew that the stripping process on the lower rear quarter panel was going to be messy and dusty so I decided to enter my blue period and drape everything adjacent to the work site with blue tarps to keep the dust and debris off them. The only thing i couldn't drape was my lungs and even with a proper breather using dust filters hung off my face, my lungs still had to deal with the stuff. About the consistency of toxic flour and half as tasty. When your sinuses start to bleed, then you know that you are not having fun annn--ymore.
As for the rest of the trunk panel, it went back into the tool shed for the winter. By dissecting this portion off the complete assembly, I no longer have to wrestle with the whole mess. The objective of all this is to score that drop panel intact just in case my archeological exercise in the quarter panel reveals that the OEM panel is crippled or has succumbed to rusticular cancer. They are not an item to be found as a matter of course on a shelf at the dealer's, so having one jic from a hulk is worth the effort of having to dissect it out of its location. Something on the order of 24 or more plug welds and a lot of Steck Splitter "Encouragement".
