Today I completed a combination cart , the original plan was in ShopNotes but I modified it to accomodate clamps also . It is 96" long by 32" wide made of plywood and 2x4 lumber with 3/4 PVC pipe as dividers. I notched some perforated angle to hold the clamps.
Great looking cart. I, too , wish I had enough room for such a cart. By the way, there isn't much dust in that collector bag - you must be goofing off and not working.
