the old trucker:
 Swamp Dawg would you know anything about U.H.M.W. polyethylene ?? I can get it in a 3" thick roll. They tell me it's tougher than steel. Think it's any good for bushings instead of brass ?? I have to start watching my budget. Ha Ha Ha. I have posted a spec sheet below.

UHMW polyethylene is an outstanding choice in material when you need a relatively low cost abrasion, impact, and chemical resistant material. UHMW is used in extreme wear situations such as hopper liners, conveyer systems, marine fender pads, and sand and gravel movement. UHMW is not uv stabilized and will have a shortened life if used outdoors.

the old trucker:


Members of NT., google  garlandmfg.com. Have a look around. There is a menu on the left side, look up applications & check it out. Seems like it should be great for making bushings for the bogies... & at a fraction of the cost of brass. Brass is what.. $70-80 bucks a piece. This stuff is about $20 bucks each. I can buy it downtown for $32 dollars for a 2 ft. length. The machinist says he can do all 8 in 1.5 hrs.
  What do you think of it ??
It's the stuff they use on snowmobile sliders & sprockets.

kpm:
I know Dan Shavers does a great job on his!!

the old trucker:

   I would say Dan does an excellent job on the parts that he builds. It's too bad that I live so far away from him. KPM, I'm trying to keep the cost down. My stash is not so big as it was. Gotta rebuild it.
