Gears and Mixer...

Having just been messing about with the Roto Truck set, I mentioned that the 24t pinions mesh at ½ inch spacing with the 12t gear. So tonight I have put together a couple of 2:1 gear boxes, one using conventional brass gears and the other using the modern tri-axle 12t and 24t gears.

Both of these gearboxes give a 2:1 Ratio

Using the modern parts in combination with the older 'Traditional' Meccano can make a lot of sense. Our miniature fairground models were a good example of this as was our transporter bridge model. The powered 'trolley' was built using eighteen plastic pinions which significantly reduced the weight. 

Plastic 19t tri-axle pinions transfer the drive to all the flanged wheels
