In response to Mike Miller's question on sheet metal edge treatment and Frank Hinde's response, the "wheel thingy" Frank referred to is an "edge former", available for $39 from Cleaveland Tool (cat. no.EF60). It does a great job and the riveted joints look very professional. You can get a similar result on a straight edged part by letting the part hang over the edge of a worktable by about 1/4 inch and gently tapping the overhanging edge along it's length with a rubber mallet. This takes practice to get a really good looking result and it doesn't work so well on curved parts. I've tried both ways and I recommend the $39 tool.

I made a perfectly acceptable edge-former out of those nylon spacers
sold in hardware stores. I got a pair of spacers about 1/4 inch thick
and about 7/8 diameter with a 3/8 hole through the middle. Put
another 3/8 ID spacer in the hole as a bushing, then using a washer to
hold the 7/8 piece, screw through the bushing into a piece of wood
with some aluminum behind it so the edge of your skin will slide nice.
Really just a few minutes of work and it does a fine job.

I've got a similar tool, but it doesn't work on curved parts like
inspection covers (which is the only place I really need it). Does
anyone know how to create that edge on inspection plate covers?

I attended an EAA workshop on sheet metal work last weekend. One method I learned for forming the edge for a inspection cover is to make a wooden form with the same outside dimensions as the cover. Next, use a file or a sander of some kind to put a bevel or rounded edge on the wood form. Clamp your cover on the form and then go around the edge with a rubber mallet or plastic hammer and tap the aluminum into the desired contour.
