Here's my DIY tank stand as of now. I will be wrapping the frame up with white birch 3/4" plywood and mohagony trim peices here's some pics. I worked mostly at night lol. I still have to add the center box frame but other than that it's almost done.
Well yes and no. I glued in biscuits into slots but I also used reversable wood screws in which they have to be forced into the wood so I am good. The stand is completely solid. You can't see the reverses but they are there. Oh and it's also bolted together in all coners and mid sections.
The Frame is 24" but after the plywood is added under the tank and screwed down it will be 24 and 3/4" tall. I still am building a center box frame though just for more support in the middle.
