I need to squeeze a 3" pipe tightly. A hose clamp would be ideal except it won't grab tightly enough without popping loose. A bicycle seatpost clamp would be good but those are too small.
I'm trying to repair a bit of bamboo that has two cracks. I'm planning to put epoxy in the crack and squeeze it shut. Is there some sort of pipe clamp that would do this? Ideally the tool would be gentle on the bamboo's surface so I wouldn't have to pad it much.
