Finished first pass of trimming on canopy. This is hard work. Riveting is easy in comparison, although when it's 95 in the garage no task is pleasant. Bought a couple more grades of sandpaper at Home Depot, and used them to finish the cut edges. Finally getting the hang of cutting with the die grinder. It's agonizingly slow until you find the sweet spot, then it's just slow. And learning how to finish the edges as I go.
