Anyone build a Ruben's tube before?

[hoosierdoc]

I'm planning to build one this week. Hoping to use it as yard art during gatherings at night. Should be a nice conversation piece.

This might help you build one. And no, it's not me.

So are you going to video it for us.

Very cool! Here's a link to a PDF document for construction :

I video nearly everything in my life it seems. I'll take some vids once it is done and a few pics along the way. I'm sure I'll screw up numerous times during construction so I can't do a time lapse video.

I built one that was 12 feet long and required two propane tanks. The material was two 4" vent pipes.

I'll see if I can dig up pictures and/or video. It is quite impressive and runs about 10 minutes before the joints overheat or the speaker starts burning. Remember to give a buffer for any joints when drilling holes. You can always drill more holes later.

Jetta, what did you use for your membrane? I am seeing latex squares, but wondering if I can use a medical glove stretched over it

Had a bad regulator and had to use one from my weed dragon. The membrane is a ziplock bag. Speaker is a bluetooth one. It is very sensitive to wind. Need to redo a few things but this can be made in an hour easily once you have everything.

don't forget a brass adapter for your tank. The above instructions use a bench top supply.

Tried the latex glove - not really strong enough. The second pass was to seal the speaker directly to the pipe end with silicone. There should be little or no gas leaking through it.
