This is another build, in Mid Red and Green, of the original model designed by Chris Shute. The colours make it easier to see the different mechanisms. Chris gives a very detailed description of the machine in his YouTube video, https://youtu.be/QuzM3TCBhek and in the article in Constructor Quarterly, so there is no need to repeat it here. I have made a few changes. The Uplifter is now driven from the constant drive, this allows better timing than the original intermittent drive. It also acts more slowly, and places the matchbox rather than throwing it! The drive for the Guide rail is also moved for better timing, and a home-made nylon cam is used for this purpose. The Box clamp over the testing finger is removed, as in my version the box is held in position by the ball rails. Also there is no Stopper, as it wasn't needed. The drive for the Opener is different. And I made an enclosure for the machine, just for fun.
