[AT] Dozer pads

[Ivan Cousins]

 I bought a little dozer over the weekend that needs some track work .While
its apart I thought that I'd like to put rubber pads on the track since most
of the garage is surrounded by cement . Don't want to go thru that again !
Ideas for pads ?  I know that the original Struck Kit used wood blocks , and
have heard of it on a few others . But I'd like something more durable .
Rubber blocks , plastic (delrin,nylon,poly ) ?  Ivan
