building my first train from wood . cant get the connecting rod correct from front twin drive wheels. do i go for big wheel to little wheel or same size wheel. my attempts seem to jam up or turn wheels in opposing directions. any help is much appriecated [?]
The connecting rod must be 90 degrees to the other side. So if the pin on the wheel of the left side is at 12 o’clock the pin on the right side must be at 3 or 9 o’clock.
thanks SPercival, much appreciated
