How do you fix it? PTFE is not something that is easy to glue. (That said, I'm 
pretty sure my old boss knows how to glue it, but I can't recall myself. I think 
you have to treat the surface first.)

Unless you have money to burn, (or a free supply of PTFE), you are not likely to 
make a chimney by turning it from a big piece on a lathe.

I guess it is easy to stable, screw or other mechanical fixing.

Obviously, for things like standoffs it is pretty good. It does deform under 
load, but that is not likely to be an issue for amplifiers. But chimneys do 
present the problem of how to fix it.
