From: Alan Lambert What he wants to do is attach Magnets to the old AF Claw coupler to have magnetic uncoupling. He does not need the magnet idea, S-Helper's Uncoupler tracksection is what I use. American Models has one And then the old AF Elecro push button Uncouplerfro the old AF track. I don't git what he is trying to do wither. He needs to go into more detail. The new Flionel Elecromatic couplers do not work by magnatism, If that is what he is trying to copy. They do have a solonoid , but that is not a (magnet). Maybe I'm wrong. Alan

Maybe lowest cost yet.. I'm not certain exactly what you're trying to do in the uncoupling process. The Kadee's work with an electromagnetic ramp because it's very easy to us it's force to move the decender (air hose), while with the AF type uncoupler you need a mechanical force to raise a plate that lifts the coupler pin. I would guess the need here is stronger than the Kadee type. If you're stuck with the AF style coupler purchase the SHS or old AF uncouplers and see what wire and mechanicals they used. If you're going the Kadee route, then either use what Bob describes, the Kadee manufactured ramp, or you can make your own electro type. I used a design used by a well-known local modeler. He used the metal 'girder' material used to hold light fixtures between floor rafters. They typically consist of two telescoping pieces. I cut mine about 2" and wrap my wire in and around the slot. Recently another friend built me one that might be more effective. He uses just 2 steel plates maybe 2" square seperated by a bolt. Wire in then wrapped asround the bolt. I haven't yet installed it but have used them on his layout with absolute success. I'm not an expert by any means but-- the more wraps and the thicker the wire the more force you'll get.

I started looking up magnetics, wondering if there was a low cost option out there that didn't involve a fortune. The most basic of electromagnets is a nail wrapped in coated wire. Supposedly, the more times you wrap around, the stronger it gets-and hotter. F
