Tread material [TANKS]

[<mxlyons-at-cox.net>]

If you need tread material and can't find treadmill belt, I saw some stuff at Home 
Depot that *may* work.  I haven't tried it, so take this for what it's worth.

In Plumbing, it's called PVC Shower Pan Liner (or similar).  It's gray, comes in 4' 
wide rolls and sells for $4.98 per linear foot.  If you only want one joint per 
track, you'd have enough for several sets.  It seems flexible yet strong, obviously 
waterproof.

With the PVC cement (as used with pipe, along with Purple Primer etc) is a similar 
cement made for this shower pan liner.
