It apears that you understood what I was getting at about the bottom and side pieces. Scolley built his with the glass on the bottom, Wendle put it on the inside of the vertical pieces, and I wanted to see how Oceanic did it.
I am not concerned about the weight because the floor is concrete slab, so I guess I'm lucky there.
I have been quoted $350 for all the glass in .5 inch and I have just about all the tools already. The tools I don't have, the corner clamps, I was planning on buying anyway for the cabinets. I only need silicone, which is $6.50 a tube for scs1200. I'll buy a dozen to play it safe. After considering the cost of the materials for the stand, I think I will still come out well ahead. All Glass brand 180s go for over $600 without shipping and they still have the trim that I don't care for.
Ah acrylic... It is beautiful but I find they scratch too easily for my taste and my son likes to "drive" his hot wheels on every inch of our house, including the aquarium.
