I really liked the wooden pallet coasters included with pro, but I wanted something with shelves to hold some of my materials. I liked how this came out and was WAY easier to glue because of the wee notches I cut in the shelves that helped immensely with the alignment:
Note! Slats will be one short per shelf since I was trying to cram as many slats as I could onto some existing off-cuts I had, but it turned out a couple of the slats didn’t quite cut right so it was good to have some extras. Works real nicely for 6x12 and 5x10 materials along with random smaller off-cuts:
I wound up gluing a couple pieces of draftboard diagonally to the back for extra stability since I plan on keeping a ton of stuff on it, but it was still pretty sturdy without it. Still haven’t quite figured out how to design for cross bracing, but I’m strongly considering a remake of this with 1/4 inch wood that’d be big enough to hold full sheets of material, so I’ll update if I figure out how to do that .
If you went extra wide with a large piece, with finger joints across the back it would be like a rock. Only slightly less so would be to box in each pair (and spread them twice as far apart.)
Think triangles. More in your design than the pallets as their height is much less than yours. A square is weak but make it two triangles and it is very strong.
if you do a flat panel on the back with cutouts and the shelf files put the notches, you can put the panel across the entire back and it wouldn’t move at all. kinda like the back to a bookshelf.
Like the little cutouts you have for the shelves for the slats to sit flush along each arm, you can do 3 across the back of the arms at the top bottom and middle and it with strengthen the whole thing. the slats would be flush with the back and you can still leave the spaces for the weird pieces.
NP, let me know if you get it working, i want to build one of these for my storage area when im working on signs and they are in different stages. I’m running out of workbench space.
