Ok AAR is doing it the professional way with a body in white and all the tools and engineering in the world. I am doing it in my garage with a a regular body and most of the tools.
Edit: I just noticed there is no stage 1.
Stage 1: But a 99 JDM spec Altezza with a blown diff, and Strip it to the balls. EVERYTHING must go. Shame really as the interior was in decent shape.
Stage 2: Clean clean clean clean. Have to take off all the crap that the factory puts on to keep out water and cut down on road noise. Ive been using a combination of a Sharpened paint scraper and a 4" bench grinder wire wheel mounted to my angle grinder for final cleaning down to the metal.
Stage 2.5: I got ahead of myself and did some welding on the front shock towers. I ve been doing the drill and fill method where you drill through the first piece of metal only and fill the hole with weld to join the 2 pieces.
This method has some advantages as it seems to add the least amount of weight and you can get some of the underneath pieces from the top by following the spot welds. However my A-hole engineer friend came over and informed me that where as it does add alot more strength the the joint a seam is stronger. Think a button shirt and a stitched seam. You are trying to stop the sheets from buckling and flexing between the welds. So alot harder to flex between the 1" long weld. The question is how much stronger? He didn't know. So i think in the key areas i will do a combination.
So im back to clean clean for a while, so i can start the cabin area and jump around the whole thing so as not to add too much heat into any one area.
Im sure this is more academic for you "Lexus" drivers out there. I drive a Toyota.
