Actually completed this quite a bit earlier this year, but never posted it.
I posted a while ago in the "Off topic" section that my other hobby is fishkeeping (really a distant second to woodworking). Anyway, I regular a fishkeeping forum and post some of my woodworking on there also. I was contacted by another forum member and asked to build a stand for a large (225 gallon) aquarium. This is the result.
Top and bottom are 2 layers of 3/4" oak ply. Edged with 1x3 solid oak. Oak frame and panel doors. The octoganal pillars are a design I had used on another stand I had built, and is made up of 3/4" oak ply as well. The whole thing is stained to the customers preferance and several coats of poly applied. Very very solid and water resistant. The cabinet are will house filters and other equipment. Not a real tough build but getting the 22.5* angles for the pillars exact was a bit tough on my old table saw.
It is just a hair over 6' long, 2' wide, and 30" tall.
Anyway, I think it turned out great.
Thanks for looking.
