Chainsaw Repair

I need to get one built out of metal similar to that one. That might be a summer project for me.

These are the ones the NYS Lumberjack Association use at all of our shows.
They're used for Stock & Hot saws, crosscut, singlebuck, and bowsaws

Here's my cant / log stands I built in development for the last 10 years. Will take round or square log, also verticle block for standing block chop. Just bore cut a slot with chainsaw on bottom end of block for the 4" strap to go through and winch down solid.
Newest  ones for ground use will be 6x6" aluminum hinged to fold up flat and 3/4" plywood also hinged to fold in half.

I read above 18" to the bottom of the cant, is that the standard height for saw contest or is that just what you made for personal use?

In my area midwest for cold start racing yes (saw not started setting on ground with hands on cant).

Varies everywhere else and  depends on show.
