Irregularly-shaped rimless acrylic tank build
Hi all, been lurking for a while, looking to start planning my build and I had questions about what thickness of acrylic I would need to use to achieve a relatively safe rimless design.
I've seen all the calculators and have put in similar dimensions for what I've got in mind, but here's my problem: I'm planning a hexagonal build, with the front and rear panels being elongated relative to the two other faces on either end, making the front and rear panel shorter than the overall length. Many (all?) of the calculators only deal with rectangular builds, but the project I'm cooking up works much better as an elongated hexagonal prism/octahedron shape.
The height would be 21"and the water level an inch less, with the front and rear panels roughly 30" long, and the two panels on either end being 10-14" wide. I was thinking 1/2" (12mm) cast acrylic would be sufficient without bracing, but I was talking to the owner of a local aquarium supply store and he recommended 3/4", or to put triangular corner braces in all the 120° corners on the top edge if I decided to use 1/2".
Does anyone have a good resource to solve this, or know of a more definitive answer?
Bump: I should mention that I'm not at all worried about the cuts, lengths, and miter angles being off; my uncle has pro-grade everything in his shop (where I'd be building the tank) and he's a cabinet-maker by trade.
