It would have to be hollow since a solid one would be too heavy.
Right now I'm focusing on making the fitting to go into PET carboys that will make it easy to transfer with a CO2 push.

Delrin would be a good choice...maybe even some of the high durometer rubbers....

I have some delrin round on hand already. Once I start working again, I plan on getting the lathe tool that will allow me to create balls/rounds. I might make the tube ends out of PTFE stock. Or something that can handle temperatures above 220F. I could use the same material for the top end of the outer tube (to guide the cane).

Golddiggie,
If you (or anyone else) ever builds one of these, send me a PM if you're interested in selling one.

Delrin is a poor choice as it is not as dimensionally stable as other polymers. Delrin is one of the worst polymers with respect to water absorption, but it has gotten better over the years. Still, other materials are better. Skip the delrin and thank me later.

I'm still thinking about this. I'm also working on a way to use a CO2 push (easily) with PET carboys. Just need to drill a pair of holes into the first unit to see how it works. Need to test it to ensure that it comes out of the carboy before the pressure inside gets too close to tolerances.
