Thanks modelman! Casting the hinge pin holes is a brilliant idea. Saves so much more machining time. I will try to incorporate that in to my next molds. What's the strength of the epoxy your using? How are they holding up on your shovel?

I have considered using resin or plastic but I'm hoping to get the metal tracks going if I can. I have some hard urethane plastic that I will try out later. It has a tensile strength of 5,840 psi.

Thank you for the pictures.
