Thank you, these are both great.
I built a rack of multiple U's that sits on top of my cheap lawn mower trailer. I can drop multiple branches in and cut through them all at once. It works pretty well but I think I want one of these too.
I can like the fabrication and ingenuity. Especially the throttle setup. But really, as fast as he is working, the saw could be left fat and the throttle pinned. A good sawbuck setup is likely faster. And that thing is a fatality waiting to happen.
