Since I installed a Ballenger mast hinge, I've had the mast up and down twice. I used the boom as a gin pole. The process filled me with great anxiety. I didn't think the mast had enough lateral stability. In other words, it could start tipping off to one side or the other.
This time I decided to build an A-frame along the lines of the link above.
I used a larger hinge. You need to line up the holes for the 1/2" by 10" bolt with the A-frame open, since the angle changes if the A-frame is open or closed.
At the base of each leg I installed an eye bolt and lashed it to the middle chainplates.
I overlapped the 2 X 4s on each leg about 7 inches instead of three. I think it should overlap more or maybe they make a metal sleeve that could be used.
First the mast is moved forward and the mast hinge connected. Then the A-frame is laid on top.
