It's almost embarrassing to show a picture of today's progress. Who would have thought that a couple of tiny wedges would make up my entire shop time today! It's hard to describe where these go, but they are a part of where the canopy side rails connect to the front portion of the canopy frame. They basically just act as a spacer where the angle of the frame changes as the longerons angle downwards.
They weren't hard to make, but they took a while. The size of them meant they had to be cut out of a big aluminum bar (no manufactured bar stock has the 5/32" thickness). It was slow going because of how fast aluminum heats up when cut/sanded, not to mention how hard it was to hang onto these while sanding. With work gloves doubled up under leather gloves, I could still only hold onto them for a few seconds at a time during sawing and sanding before I had to dunk them in water to cool them off.
