There isn't usually anyone around to help me tear down or setup a pin. So I needed a tool to allow me to setup/teardown a pin by myself. And on the cheap of course...
I bought a couple 2x4s and some screws and came up with this:
Start with folded torn down pin
1)put on front legs.
2)lean over on front legs.
3)pick up the pin from the back
4)slide the prop in place
5)install back legs
6)lift up on back and remove prop.
Reverse steps to tear down.
