This is a very simple design that I found on Pinterest and couldnt locate any origan designer to credit. Just to be clear I didn't originally come up with this, in fact its so simple i know there are commercial products of this exact concept (because there is one for brooms that came with my shop).
I just wanted to share my take on it and offer some advice if anyone else is looking.
Step 1: Materials
I also used drywall screws and glue for the joints.
Step 2: Cutting and Construction
2 peices of 2x4 13 inches long
1 peice of plywood 5x10 inches
2 plywood triangles approximately 11x5 inches at the right angle. Those lengths are not thr hypotenuse side.
1. attach the triangular plywood peices to the rectangular peice. Make sure the angled portion of the triangle is pointing down.
2. attach 2x4s to the backing board with countersunk screws.
3. attach the triangles to the 2x4s with screws.
4. drill mounting holes in the backer board.
Thats really all there is to building the racks.
Step 3: Mount Racks
You can see in the photos i left the space between posts walled off to hold the really heavy stuff like slege hammers and steel breaker bars and tools that wouldn't have the right shape to hang properly.
These are quick build, take up no floor space, and hold a lot of tools. A big benift over my last design is the ability to stack similar tools almost on top of each other in stead of leaving them in a row.
