Longtime lurker here! I wasn't planning on posting my Fett development until all my softparts were complete (which is one piece away), but once I discovered this thread it got me super motivated to just try it out. I managed to get the exact 13 gal can, unfortunately no 8 gal so I just grabbed one of the smaller 4 gal bathroom types. So, using the Wizard of Flight's templates, the recommend tin snips and scoring method I went to work. The whole think took only a couple of Spagetti Westerns to complete. (BTW, expect your hands to be in the shape of claws when it's over) :facepalm
The most difficult part was transferring the templates as they were printed out on standard printer paper, it took many swipes with a thin sharpie and straight edge to get a light transfer through, I was able to then go back over with the sharpie.
The cutting of the shapes with the snips is fairly easy but kills your hands as does the scoring on your fingers. I continued to use the metal straight edge to score at the outlines. Once you see just how perfect the plastic snaps off, you'll want to work quick. However, don't get impatient with this step, really score it down. If you rush you may accidently crack one of the piece. If I'd just slowed down a bit, my cod would have been perfect.
If you place the templates right, you may not need to reshape anything. However, I just used the boiling water techinque and the stuff reforms nicely. I have to give major props to AFettFullofDollars for starting this whole deal and Wizards great templates. I'm a novice craftsman at best and everyone was majorly impressed with what they saw laying on the kitchen table.
Here's my results (the cod is missing the center piece):
