two, three foot long pieces of 2 x 6
one, eight foot 2 x 4 plus a few pieces
one, strap hinge
assorted screws and bolts
glue and finish
The head piece is made of two, three foot long pieces of 2 x 6 hinged together and closed with a hasp. I clamped the pieces together, measured for the head and hand holes and cut them out. I then glued and screwed guides on the back and front faces.
The base is a simple 2 x 4 "H".
I wanted the middle of the head hole to be about four feet above the ground so I measured the uprights accordingly. I also wanted the head piece to come off easily so although I bolted the uprights to the base, where they held the head piece I made saddles out of short pieces of 2 x 4 for the head piece to fit into.
