G'day Stefan
PTFE can be glued (Haven't done it myself) using Loctite cyanoacrylate glue
with a priming fluid.
The combination apparently required is-
Loctite 406 adhesive
Loctite 770 polyolefin primer
Cheers
Brian

good idea.
But can't be glued, right? would not be easy to affix a bearing block to
the rest of the tank...
But not impossible i guess...
Maybe a titanium stud can be mounted to the bottom of the tank, and a
teflon disk fitted in the totating tube, with the 3 holes as described to
let etchant in and a smaller hole in the middle to accept the titanium
stud.
As dimensions are no issue titanium round stock and teflon should be cheap
enough at ebay.
Going that way would need several lengths of electrical tubing until one
has worked out the right nozzle size and pattern. I would kind of like to
be sure it works with CuCl and toner transfer before spending any money on
it...
