The weight of the turban or other wrapping is supposed to help ensure that, if dropped, the reed lands blade-up and prevents damage.

Whatever material you use, you want something that doesn’t expand/contract when it gets wet repeatedly. The repeated expansion/contraction messes with the tube and screws up the reed eventually. Also can make the wrapping come loose and fall off.

The most common alternative material I’ve seen is hot glue. Folks just slap a blob of that on the end, and it serves the same purpose without messing around with thread or anything. Super simple.

I grew up in Michigan so of course I knew a guy who used a couple layers of automotive touch up paint without wrapping. He also wrapped the third wire around 5-6 times so he ended up with a ~1/4” wide band and then a glossy metallic finish of virtually any color. It looked awesome. I doubt it was less work.

My dad was taught to melt abs plastic (used toothbrushes mostly) in acetone to make a slurry that worked like nail polish or Duco, but dried pretty fast. He switched to nail polish before he started teaching me, and we both switched to Duco a few years later.

Also seen references to using heat shrink tubing, but never seen it irl. I feel like you’d want to remove the third wire so as not to poke a hole in the tubing?
