3/4 Inch thick solid Maple plywood. Framed under with 2x4s every 8-10 Inches.
Got some of the stain work done. Ran out. Got more in today and will work on it a bit in the morning. Starting to lay silicone for the glass panels and need to cut a strip to seal where two panels meet in the middle. Then cut the last few trim pieces. Corner and center glass supports. Finish staining.
Waiting on Jehmco for the bulkheads and misc plumbing parts. Should be here Wednesday. Hoping to start filling it Friday or Saturday. But will probably be next week if work keeps being busy.
