Re: How to attach axle to FisherPrice gearbox?
Last season we found a description of an interface here on CD and re-created it ourselves. I wish I could find the link, but no luck.
It is created by drilling a circular hole with the same diameter as the transmission output. The holes are the same diameter of each finger, or tab, on the transmission. We then drilled and tapped for a 1/2" shaft. Finally we cross drilled through the entire assembly.
We ran this through one regional, Nationals, Cal Games and MadTown and NEVER once had a single issue with it.
