Building a Climbing Ramp

We wanted to build a (human) kid’s climbing ramp (sometimes referred to as a pikler arch / montessori arch). We found a bunch of varieties and styles on sale online but decided to try building our own.

We decided to make it approximately 4 feet long. We started with a 8 foot long, 20 inch wide board.

First, cut it in half to end up with two 4 foot long sections. Stack those two sections on top of each other so when you then measure and cut the arch, both sides automatically match, even if the cuts aren’t exact.

Drawing the arch on the board before cutting. The outer arch is based on a circle with a 24 inch radius with the smaller curved lines based on smaller concentric circles.

With one 20 inch wide board, we cut out 3 separate pairs of arches. While we have only finished the larger outer climbing ramp to date, we have plans to make 2 smaller ramps in a similar style when we have the time.

After drawing out the ramps, cut out the arches using your jigsaw. For the slats, we cut out ten ~23 inch long pieces from 1″ x 4″ boards.

The cut outer arches along with a sample of the slats.

After cutting out the arches and slats, it is time to round off all of the exposed edges and corners with a round off router bit to eliminate any sharp edges.

Once the routing is complete, it is time to sand all of the surfaces with several levels of sandpaper – we used coarse, medium and fine on all of the surfaces.
