And what is the 24v power source you use?
Russ Bellinis wrote:Gary, I like you uncoupling magnet design. I'm curious, do you use Athearn cars with steel weights or Athearn cabooses with steel ladders?
Russ Bellinis wrote:I'm asking because I saw a similar product at a train show recently. I can't remember what it was called, and the guy making them out of his garage doesn't have a web site, just an email address. I took his brochure with me and after reading it over, I found that he did not recommend any steel be in rolling stock. None of the Athearn steel weights or Tichy's use of 1/2 inch steel nuts for weights or Athearn's steel ladders on cabooses.

Russ Bellinis wrote:Also another question about the Kaddee O-scale coils. Will they stand a short period of time energized, or are they a momentary type that will burn out if energized for more than a few seconds? One reason that I haven't considered using Kaddee Ho-scale electromagnets on a module is that when we set up at shows anyone in the club can operate on anyone's module, so I try to avoid any momentary contact components.
Russ Bellinis wrote:If the electro magnet just causes a car with steel weights to roll a little when the magnet is energized, that would not be much of a problem, much better than using two hands to uncouple cars or using a permanent magnet with the problem of nuisance uncoupling. My system would be operated by anyone in the club participating in an operating session, so I would like it to be fool proof. One other question, would the rolling caused by steel weights in car pull the couplers away form the magnets so that they would not uncouple? It suddenly dawns on me that a flat weight like used by Athearn or steel weights mounted in the center of the car could cause the couplers to move past the magnet or cause an uncoupled car to "follow" the train and recouple when it cleared the magnet.
