Well, I managed to get some more work done on the canopy, and attached is a photo of my progress.
I have it fully framed, with the 1/2" plywood top attached, and it's just about ready for skinning once the glue holding the lip frame dries.
You can see the hole in the top where the canopy fan will sit above (the other half of it is behind the crossbrace). The doors on each viewable side will be the size of the opening that you can see the glue through (from leg to leg).
I have a test and a paper due on Friday, and class tomorrow night, so I don't think I'll make much more progress until this weekend, but I plan on finishing the canopy then.
I got the glass panels for the sump today, and will probably start constructing that the beginning of next week (or this weekend if I get lucky).
5 pieces of 1/4" plate glass, edge-ground, ran me about $30 ( (1) 22"x7", (2) 9"x7", (1) 5"x7", (1) 12"x7")... but it'll be nice having viewing panels into each chamber of the sump, and an almost full glass front across the fuge/growout area.
