I built this with the help of avery able friend.
This is the best design for a high-chair that I’ve encountered. Instead of being enshrined in a wooden tower (or more likely plastic, these days…) back away from the table, the Trip Trapp brings the child to the table to share in the meal. It’s also a lot less to clean!
Designed by Peter Opsvik in 1972: http://opsvik.no/index.asp
We had an original Tripp Trapp for our first child, and when the second arrived I decided to try to build one as my first real woodworking project. Not the best choice for a first project! All of the angles made it quite a challenge. It was especially hard to get SketchUp to deal with the half-round angled slots. I managed to do it, but I remember that Sketchup fought me the entire way. I even asked for help on several SkeketchUp forums and no one was able to figure it out.
What you see in the photos was meant as a prototype and is made out of re-cycled pine house framing. My plan was to make another from Rimu, but other projects beckon….
If you’d like to try to make one yourself, here is a link to the SketchUp model as far as I was able to take it:
One of the photos below shows the jig we built to make the curved back rest parts. These were two thin 5mm stripps of plywood (ran through thicknesser) glued, and pressed into the jig.
I’ve also included a template I created from measuring off the real Trip Trapp of the holes at the top of the posts.
In the model you’ll see I wanted a mortice and tenon for the foot connection, but that was a bit too ambitious. Next time!
Also: Tripp Trapps also have a bent band of wood to allow it to be used with children that can’t sit up yet. I router the holes for this but did not make one yet. Probably will require steam!
