1st stage
Paint plywood panel with brown protective coat.
2nd stage
Build the frame with single pipes.
They were so heavy that it was a hard task for me to make this structure.
And, put rafters on it with clamps and screws.
3rd stage
Set the baords on the frame of single pipes.
No home improvement stores near my house sold a screw long enough to fix clamp, rafter and board together.
Thus, I had to fix clamp & board to clamp severally.
4th stage
Drive the claw nuts in the boards!
This work was the easiest in the all stage.
I want more claw nuts because I could set holds made of residual squared lumber
6th srtage
It's nearly finished.
This state requires 4 more tubes to prop thisvclimbing board up.
I completed my work :-)
Only 9 holds on the board make very hard problem to climb.
