I'm currently working on a train elevator for my model railroad, which will be used to lift trains from the lower level to a second deck on my model railroad. The main problem will be alignment, and I've already got something in mind.
What I'm looking for is a metal cutout with a 2D cross-section of a funnel. Something that looks like this:
The idea is that as the elevator raises into position, the cutout catches a peg on the end and uses that to line it up. Thing is, whenever I google or search Ebay for alignment pin, all I get are automotive components.
Can anyone point me in the direction of what I'm looking for?
