scratch built transfer bridge.

Very nice. Great work. Don

This looks very good.  Can you tell us more  about how you did it and how it is automated?

Thanks

Yes, a great piece of work and smooth operation for transfer of motive power.  Many Kudos, sir..........

That is slick, certainly more info on how you did this would be appreciated.

Going through some of my old photos. Don

Thanks for the positive comments fellows. I built this from scratch using supplies from my local lower store. Except the side rails which are called linear actuators. A few years back I found the actuators on eBay from a guy who tried to run two together and had problems. As you can see I figured out the wiring to run both at the same time (simple). They run on separate 110 volt and have a hand controller for easy use. They are intended for construction of a cabinet to conceal a tv and can handle up to 450 lbs. They are made by Firgelli linear actuators. These are expensive new, but I was lucky to find them on the bay. I even bought a miniature one from them and put it inside the chimney on the engine house to raise and close the engine house door using an H.O. transformer..will show on video when complete.   I have a few photos to show the bridge start work attached. The bridge is 30 inches as I needed to be able to move my postwar f-3 units at once. So after getting my tables lined up I cut 3/4 x2 pine for rails and inside braces, then mounted them to the mending plates attached to the actuators squared. Next is the top of bridge which was tricky as you need to square it (some overlap on each side) and drill holes for the power supply wires to run underneath to power the track, The wires are placed with enough slack to travel the length of actuator from end to end. once this was done I put the carpet on top of bridge, and centered the track placing thin strips on each side to simulate a walkway. Next was adding the side thin stantions to the bridge. (oh and painting he wood first before assembly) It's a little tedious lining up the length of bridge so not to hit anything in motion. And mounting level was time consuming due to the weight of the actuator motors, but with patience you can see it worked. Oh and the safety first side rails I had from an atlas turntable I aquird for parts, a little short but work fine for now. The major expense like I mention are the actuators, If I can answer any more feel free to ask.
