Caulk Tube Nest
Before I made this caulk nest for my shop, the tubes rolled all over the shelves like slippery logs. To build one, cut 10-in.-long pieces of 2-in. PVC pipe and glue them side to side with PVC cement. To get straight glue lines, use the print along the side of the pipe as a guide. As you glue, hold the pieces together for 60 seconds with hand pressure or a clamp until the glue sets. Be sure to apply the glue only in a well-ventilated area. Glue on one tube at a time to fit the available space. That's it— your caulk tubes are now organized.
In the plumbing aisle, you'll also find PVC and rubber 'reducer' couplings that let you connect your vacuum hose to a different-size pipe.
