Step 1: Gather Your Materials
- (4) 2” x 6” x 72” dimensional pine lumber
- (2) 2” x 4” x 8” pine studs
- (10) 1” x 6” x 8’ pine boards
- Rock climbing grips
- Large, heavy rope
- (250) 3” wood screw
- (2) 5” carriage bolts
- (2) ⅜” hex nuts
- (6) ⅜” washers
- Chop saw
- Power drill with bits and drivers
- ⅜” drill bit
- Jig saw
- Tape measure
- Speed square
- Crescent or socket wrench
Step 2: Cut Wood to Size
Pro tip: Sanding boards prior to assembly will be easier than upon completion.
- Four (4) 2x6 @ 60 inches (legs)
- Two (2) 2x4 @ 44 inches (cross braces)
- Two (2) 2x4 @ 40 ⅝ inches (cross braces)
- Ten (10) 1x6 @ 47 inches (outer wall pieces)
- Ten (10) 1x6 @ 45 ½ inches (outer wall pieces)
Cut one end of each 2x6 at a 45-degree angle. On the other end of a board, place the center point of a protractor about 6 inches from the board’s end and 1 inch in from the board’s side. Mark a quarter of a circle with a 6-inch radius. Cut the circle with a jigsaw. Use this board as a template for remaining boards. Evenly sand rounded edges with orbital sander.
Step 2: Make the Two Frames
There are two different widths of frames: 47 inches and 45 ½ inches. This is so that they can fold together with one resting inside the other. For the wider frame, lay out 2x6 boards side-by-side with the rounded edge facing up. Screw in 44-inch long 2x4s flush with side of the board with the rounded edge. The 2x4s should be placed 6 inches in from tops and bottoms of the boards. Repeat with the 40 ⅝-inch long 2x4s to create two frames.
Step 3: Attach Face Boards
These are the boards that the grips will be installed on. Screw 1x6 boards across the 2x6 boards running over and parallel to the 2x4 studs. Start 2 inches below where the curved board becomes straight and work your way down, keeping the 1x6 planks tight against each other. There should be a little room left at the bottom. Remember there are two different length planks because there are two different sized frames. Sand the edges if any planks protrude after all are attached.
Step 4: Attach Two Frames
Attach together at a pivot point. Make a ½-inch hole at the same place on every 2x6. Make it the same spot the protractor was centered on to draw the quarter circle.
Step 5: Add Finishing Touches
Attach climbing grips and rope according to manufacturer’s instructions.
