(system crash deleted original) I am rebuilding my tracks soon.
The original pamphlet for the ST states the grousers are Spring Steel. Current on my 3 band is A36 1-1/2” square tube with 3/16” walls. While the current ones seemed to work OK, that is quite a lot of steel to carry around. About 700 + Pounds of steel.
Looking at the picture the OEM grousers look to be fairly lightweight. I have read of grousers made from wood, angle iron, plastic, and formed spring steel. I would not be surprised at bamboo or T fence posts.
Looking back through posts, OP's have stated the need for heat treatable steel ($$$) heat treated ($$$$). Others have used ... SO the question is what have others tried that DIDN'T work? And why not.
I am considering cutting the existing ones down on the ends leaving the full tube in the center. Giving a taper so the harder the surface, the less material is in contact. But, having all those big square ends provides a bit of side slip resistance.
