The Optimal Climbing Pegboard Hole Size


The Optimal Climbing Pegboard Hole Size

When I built my first pegboard, I first drilled a hole the size of the peg.  I quickly realized that this hole will be too tight for climbing and the local dowel rods were not perfectly round or to specifications.  So, I went on a laborious mission to get this peg to fit. 

I used double sided tape to attach a piece of sandpaper to a dowel rod, then used this to make the hole wider.  It was partially successful but time consuming. 

The next attempt was to use a dowel that was 1/8 of an inch smaller than the hole.  This didn’t work because there was too much play in the hole.

The best combination I found is to drill a hole at 1-5/16” diameter and use a 1-1/4” poplar or oak peg.  1-1/4” is the diameter of a standard pull up bar.  By cutting the hole only 1/16 of an inch wider, it doesn’t require extra sanding or results in a hole that is too loose.

    I did the same. The tight fit makes it impossible to climb. I’ve been sanding the dowels but maybe need to sand the holes. I think if they were a little more open at the front it would simplify its climbability significantly.

    I used a 1-5/16 forstner bit similar to this one I purchased it off of Amazon. Your best option is to use a drill press, and adjust your speed down to less than 500 rpms. You will have to go slow or the heat will burn your bit. Good luck.

    What kind of bit did you use to drill the hole? There are very few tools that are of a 1 5/16 inch diameter. Did you use a forstner bit and plunge router? Did you say spade bit? Drill press?
