I bought a half dozen or so commercial shelf/racks used in the food industry. Sam's Club sells em for around $2 bits a piece. Hole sawed a bunch of 2x4's and ripped em down the center, then attached to 3/8 plywood cut to fit the shelf. They lay horizontally supported by the saddles. The shelf is for our reamer inventory/tooling and the top rack is where the sticks go. Works for us due to our floorplan, so judge yours accordingly. The shelves I needed anyway and this worked for us cause putting tooling that high up just meant we couldn't reach/see what's up there. Barrels however were a natural..
