The Meccanograph is an interesting Meccano model that can produce hundreds of different circular based designs. This model particular model I built from Super Model Leaflet 13 instructions and is perhaps one of the most popular Meccano models of all time. This SML version was published in 1928 and is almost identical to an earlier model published in the 1916 manual of instructions, this model had been a winning Meccano Competition entry and was apparently a great favourite of Frank Hornby the inventor of the Meccano system. The model with several changes was continued in the No.8 manuals until 1966, the last version of all, be it much simpler and smaller was in the 1978 dark blue and yellow number 5 set. Which I think goes to show how popular it was and still is with many enthusiasts building very complex machines. I built the model using a 1930, Number 7 set with red and green parts that at present resides in Canada. On my last visit I thought it would be fun to build the Meccanograph as an amusement for my two Grandchildren and indeed it was. We produced quite a lot of different patterns as can been seen on this page, some have a bit of a shaky line! The machine needs to be on a firm surface for the best results. I followed the instructions almost exactly except for changing the crank handle for a faceplate with a crank and short rod I had noticed when the children turned the crank handle shown in the instructions it made for a rather jerky movement but the modification made a great improvement having greater leverage. In fact this is how it appears in the later number 8 versions. I was fortunate to have in my built up number 7 set Part 107 "The table for designing machine" a part that only has one use, the Meccanograph. The part is very rare as presumably most "Meccano Boys" boys made their own from a piece of square wood fixed to a bush wheel as is suggested in the original instructions. Though it was nice to be able to use an original table, for designing machine in green stained wood. Adjustments to the position of the arms journaled in the two bush wheels enables many changes to be made to the pattern produced, gears also can be changed this changes the ratio between the drawing arm and the rotation of the "Design Table".
