A climbing peg board is a great way to build strength in your arms and upper body. It is basically a board attached to a wall with a series of holes in which pegs can be inserted. By holding a peg in each hand, you raise yourself up from one hole to another in order to climb the wall. On a horizontally mounted peg board, you can move yourself back and forth on the board.
Mark the 2x10 board with a pencil for the placement of holes. Place the holes randomly on the board, or in two columns, two to four inches The holes should be no less than a half inch from the edge of the board.
Measure 1 1/4 inches from the end of your 1 3/4-inch drill and wrap a small piece of masking tape above that measurement. The tape will ensure you do not over-drill. Drilling to this mark will leave 1/4 inch of wood behind the holes--most 2x10 boards are only 1 1/2 inches thick.
Put on your safety glasses and drill the holes you have marked to a depth of 1 1/4 inches.
Sand the board, holes and dowels with sandpaper.
Insert the dowels into the holes to ensure they fit loosely into the holes. Sand down the dowels if they are too snug. These will be your pegs for climbing.
Mount the board on a sturdy wooden wall or wooden beam with 4 L-brackets spaced evenly apart on either side.
Place a padded gymnasium mat under the board. Place the dowels in the bottom holes and test the strength of the peg board to ensure it will support your weight.
Don't mount a peg board on drywall or plaster. For those walls, you can hang the board horizontally, mounted to the wooden studs inside the wall. Alternatively, you can mount the board on 2x4's which you can then attach to the wall studs. Never mount a peg board at a height greater than you can safely fall or jump to the gymnasium mat without injury.
