It is 1¼" PVC and I just used an old travel 1200 watt hair dryer we had laying around. It delivers plenty of hot aor to dry the boots in a short period of time. Be sure to use PVC glue when assembling the pipe pieces.

Yeah, I thought the thing I made was too small. I used 1" and used PVC glue. I intended it to be able to break down so some of the pieces aren’t glued.

i would suggest gluing the base together. You can make it a little more compact than I did for size considerations. All you would need between the joints is a long enough piece to join them together. Then just sticking the uprights into that. Gravity will keep them in place and you can break it down into a smaller size.

YEp, that was my exact thought. E even had a reinforcement in the center of the upright, but the 1" pipe was just too flimsy. My wet 5 mil tipped it right over. I’ll post pics later.
