I am currently building my next project which is a Penny Falls machine which is also called a Coin Pusher. A couple of videos showing the progress can be seen below.
A interview by Dubious Engineering taken at Alexandra Palace January 2020 of the completed ship can be viewed on YouTube DuB-EnG: USS Missouri Battleship. Steve was a guest of The West London Meccano Society.
This model was built for the sole reason to demonstrate the operation of a compact 3 speed/neutral/reverse all pinion gearbox. The gearbox itself is very special to me as I built it in my early 'teens' (around 1972 I think), but it later got me my first job at the start of my career. It had been intended as the drive for a motorised model of a formula one car, but I never got further than the gearbox. However, for my interview as an engineering apprentice with Hawker-Siddeley, I took it as a conversation piece. From the moment I handed it over to the three man panel, they spent the remainder of the interview fiddling with it and reminiscing about their meccano days. I swear this gearbox secured me a place against stiff competition.
