Jib,
 
"Cheaper than dirt" is good! 
I looked on line for "toilet partition discards... and got lots of hits.  Am I understanding you correctly... if I can find one of these places locally, I can go there and they are likely to have discards, that they'd just hand out because its cheaper than them having to dispose of them.  Is that right?

I use HDPE (polyethylene) toilet partition discards.  It is solid throughout and generally 3/4" thick.  It is not UHMW "I think" but it is strong and very slick.  Easy to cut. tap, finish with wood finishing tools.  It is a great material around water and any supplier or installer has more pieces and colors than they need or want......I. E. no money transaction. Cheaper than dirt.

Recycled UHMW is a cheap boaters friend. Here in the US Mcmasters Carr has recycled UHMW in several sizes at reasonable prices, I'm about halfway thru a 3/4" X 5-1/2" X 6' piece that's been used for bearings, fairleads and tip plates (which are a form of bearing plates in my case). I'm not a real fan of PVC pipe (except as clamps) since it lacks stiffness, but have been known to grab a piece and heat flatten the ends when a short reinforcing strut was called for.

cheers,
