Hey guys, I used this thread as a basis for how I would build my own bag cart. After browsing Home Depot, I came up with this. Heavy duty shelving brackets, nylon pegboard, steel frame handtruck, PVC and 5/16 hex bolts. I would like to extend the bottom lip and maybe add a second shelf. Also I had swapped out the solid neverflat tires with pneumatic ones. This thing feels rock solid.
