Bottom of Pad
This is the last piece of the pad. It is one big
piece of 33 inch by 33 inch peg board. I used the
rough side of the peg board on the bottom so that
the pad won't slide around. I pre-drilled all the
holes and screwed 1 inch Phillips drywall screws
into the MDF rails. I then labeled all the holes
where the screws go just in case it needs fixing.
If you decide to add the backpiece for added safety
then cut the bottom peg board 33 inches by 35 inches.
