webbing for track systems [TANKS]

[Gary Warren <gdubb2-at-cableone.net>]

Hi All,
Living in Sphincter, Idaho, leaves something to be desired for parts 
availability.(Other than mail order)  A thought came to me this morning as 
I was looking at the TTS track system.

  Has anyone tried webbing??  like seat belts etc. It is available in 2" 
widths, and in Nylon or Polypropoline. One would have to use 2 strips  to 
get 4" wide, but it looks like it might work, and can be had as old seat 
belts, or at craft/sewing shops. The seat belts in our car is .050 thick, 
which is the same as the belt on our treadmill. (wife says I can't have it 
though)

What do you think???

Thanks
Gary Warren
