I'm making the paint station out of mainly 3/4" pine and 1/4" press board. It's actually a very cheap build using scraps from the spray station I made. Sadly the 2'x4' press board sheet was 1 1/2" short and I'll need to get another 8( .. blah. But it's not much just sucks I couldn't get it all constructed last night. Now I'll have to get the board cut it and then glue it plus cut all the holes hopefully tonight. And it will be a ton of holes .. a ton. Here's some of the maths..
Some of the shelves required some clamp love.
