Jungle gym

My wife suggested I make some sort of a jyngle gym for the kids. I agreed but warned her that it would take “a whole weekend”. Nine working days later (six days of my own time; three of those with my dad helping me) the contraption is ready (excluding the railings surrounding the deck, to be made of thick rope).

Made of Siberian Larch. My own design, using Google Sketchup (if somebody is interested, I can try to post the actual file). I tried to add strength during the building process by making the deck diagonally, and by adding some diagonal corner supports. I also tried to pay special attention not to create any spaces where a child’s neck or head could get into a bind; towards that purpose I filled the gap between the diagonal corner supports and the actual corner with diagonal thinner boards, and lifted the “skirt” of the climbing wall clear off the ground.

Hardest part by far was the foundations: Figuring out the vertical measurements on the ground with a self-made water-hose-level, and making & positioning the concrete feet in the right positions both vertically and horizontally. I built a separate jig that held in place the metal feet while the concrete (in up-side down turned buckets with their bottom cut out) hardened.

Looks like great fun. My estimate would have been a weekend, too. But my wife automatically doubles or triples my estimate.

Say – can you tell us more about the dados in the big vertical timbers?

The verticals are made of three separate boards; two larger boards sandwiching a smaller one in the middle. The horizontals rest on the middle one, and the “insides” of the outer boards have been routed to create a mortise for the horizontal (which thereby becomes a tenon?), or alternatively a hole for those horizontals which meet the face of the vertical. Hard to explain without a picture…

I don’t know how to post the sketch up file here, so if anybody else is interested I can email it directly upon request. All of the diagonal structures (the “triangles” you see in the main pictures, the diagonally set deck boards, and opposite diagonals underneath the deck) were added on-the-go to make the thing more rigid. Seemed to work, as it is still standing more than 3 years later.

Here are some detail photos of the joinery to help interpret the plans. The material is Larix sibirica, which does not need any finishing. It turns gray, but withstands the elements otherwise.
