Nice
Mine is pressure treated wood on the inside. I suck at wood working. I wish I would have had someone to help. Maybe I'll try that stuff on the inside of my wrap.
U can't see it in the pic but there is one 2x4 on the inside and 2 2x4's on the out side Jamed In between the top and the bottom of each corner. On top of that there are heavy duty brackets on each corner top and bottom. You can see in the pic I also put 2x4's going width wise on the top and bottom. I also have the inside leg trap between 2 2x4's. I put 4 or 500Lbs on top of this thing as a test and it didn't even move.
The pieces of lumber he used look treated to me. You can see that they have a green tint to them.
Hate to bring this up, but treated wood is just about the worst choice possible for building a stand. Not only does it tend to be rather wet, and so prone to warping/splitting as it dries, it is usually treated with copper. You will have to allow it to dry well so that it can be sealed properly. Not doing so could allow an avenue for contaminates to get into your tank by way of splashes/drips, etc.
When I first got the wood it was wet but now it's dry. I've been working on this for a while. Haven't had any problems so far but thanks.
