A little tip: When riveting thin aluminum sheets together with with AD rivets, it can sometimes be difficult to keep the two sheets tightly together as you squeeze/set the rivet. The result can be a slight gap between the sheets.
I have found that by placing a small (@1/2" x @3/8" x @3/16") piece of rubber with a @1/8" hole drilled in the center (I use old orange silicone baffle material) over the unformed shop end of the rivet and then squeezing/setting the rivet, the rubber piece creates pressure which keeps the two sheets tightly together during the squeezing/setting process.
Be aware - the little buggers have a tendency to fall to the floor and get lost, so make several of them!
