I saw one of these on a You Tube Video and thought it would be a good exercise in Sketch Up. I managed to build one from the drawings I made although had to alter a couple of things along the way. The Sketch Up drawing is now up to date and I have posted below a couple of images from the Sketch Up file.
The actual final model has the addition of exterior fitted dowels on the butt joints. The mechanism is quite smooth to operate.
