I've been looking for a less expensive material for my freight sled bottom and had what I hope will turn out to be a brainstorm. I use 30 gal. plastic barrels (soap barrels from a carwash) for fuel storage and noticed the plastic seems to be similar to UHMW. The code on the barrel is HDPE, and a few websites I found said it performs well as runner material. I think if cut at a slight diagonal you could get some nice long strips of it and it would go a long way. I know it's softer than UHMW, but it seems like a very inexpensive alternative. Anybody out there tried this material with success?
