DIY Tip of the Day: Tape Dispenser Caddy. Keep your tape rolls in one place with this handy tape dispenser. You’ll need a 1 1/2-in. dowel, 3/4-in. plywood and a hacksaw blade. Notch the sides and screw everything together. Saw the dowel ends to fit in the notches and screw the hacksaw blade on with the teeth overhanging the plywood. Fasten the dispenser to the workbench. Thanks to R. B. Himes for this idea!
