I was asked again the other day at Railex (no I wasn't there with QUAI:87) as to how the swing bridges over the canals were driven. Again I gave the truthful answer - Tortoise point motors - only to see the enquirers eyes glaze over, and the unspoken questioning look, how does a device that by its very nature only gives a 1/4 inch or so of throw move a bridge through 90deg. As the mechanism is impossible to see on the layout and as I was preparing yet another Tortoise, this time to drive the newly installed wagon hoist on the layout, I though I'd put up a pic to show how I convert a point machine into a winch. (Product guarantee out the window [there's a whole pile of them of one sort or another outside my window] but sometimes one has to live dangerously). The Tortoise taken apart all the gubbins that they don't want you to see is revealed, and the cam and blade moving bits and associated slider switches are discarded, leaving a rather nice winch type mechanism that can be used for all sorts of things. I drill a hole in the final output shaft (very undrillable plastic but keep at it) to attach a cord. The rather heavy string shown is not as usually used but is for illustration only as they say. I also invariably install a short length of knicker elastic (kindly supplied by Lady ZOB) in the final drive line to give a bit of play - I hadn't done this on the first test run and found, not to my surprise that the Tortoise is powerful enough in this unintended configuration to lift the whole wagon hoist out of the ground. They had bent coathanger wire on the swing bridges before the elastic was installed. Incidentally I power the bridges and now the hoist with a regular loco throttle as this means I can have a beautiful slow start up of the bridge and an even more prototypically 'slowly slowly' docking of the bridge in its final position. Hope this is of some interest, Brian.
