Free BIG Track For BIG Robot!!


 I got this:


This are 10 FT (3.048 m) of Rexnord Table Top Chain, They are plastic on metal chain, model D843K3-1/4.

I tink that this track can be used in a nice and big robot track, if the plastic is sliperry can cover it with anti-skid tape for more traction.

IF someone is interested on this, only have to pay for shipping to your location anywere in this beautiful world !!!
