If you are going to dispose of the sheet metal for scrap, there's a trick to it. You see, the recycling yards hate airframes and it has to do with the rivets, not sure why, but I've done a couple now, and it's been that way, so you have a bit of work to put in cutting out the aluminum panels from between the rivet lines.
The best way to do this is I found is with a 4 or 4.5" pneumatic 90° cut-off/grinder and a Multi-Cutter blade. Basically a ripsaw blade for non ferrous metals. You have to be careful with this rig. It has to be pneumatic, yes, you'll need to buy or rent a compressor. You can actually rent the whole rig for a week cheap enough. Never use a little electric grinder for this, they have too much torque, and when they catch (and they do) the results are often tragic. A pneumatic one just stops with barely a twitch, it has no real spinning mass or torque to the motor. We use this rig building aluminum boats to cut and fit plates and components. If ever an apprentice was seen with an electric rig, he was fired on the spot and escorted off. Either he slept through the in doc video on the use and dangers of the Multi Cutter, or he wasn't impressed with carnage that was documented there in.
What I do is cut and stack all the clean aluminum in one load and get premium recycle value for it, then haul in the crumpled load of seams and rivet lines and take the discount price on it. Otherwise I take the discount price on the whole thing, and the difference has always been significant enough to be worth the effort.
