I wanted the shelves to be extremely strong and have a good size lip to keep stuff from falling off while I move the rack around. I typically over-engineer my projects, but with as much weight as this rack has on it I am very glad I built it solid.
I glued and screwed (with pocket holes using my Kreg Jig) the A-Frames, but I decided to keep the shelves without glue so I could break down or change the rack. The long shelf sides are the rails that connect the A-Frames so I put 2 pocket holes in each rail.
The pocket hole placement on the bottom of the shelves probably doesn’t matter, but I like to lay out the pocket holes pretty consistently. For strength of the assembly, I used a lot of screw holes.
I use the sawdust hole to align the pocket to my layout lines.
I assemble the shelf attaching the bottom to the sides and rails.
I take the ends off and attach them to the A-Frames.
I mark the center on the bottom and the end rails for alignment for reassembly
Here is the attached shelf.
