Found a GREAT idea in Railroad Model Craftsman magazine about using strong magnets for uncoupling. Nov. issue, P.83 thru P.87. It's called"Dual Magnet Uncoupling". The first time I bought 50 magnets from the co. that they list in the mag. I made 25 uncoupling spots in my yards. They worked so well that I bought 100 more. I have enough now to finish up the rest of the spots.
A cpl. guys that came over decided they needed to do their tracks the same way. I was using between the rails Atlas magnets, but they don't work everytime. And I use the under the track magnets, but these little barrel magnets work 100% better.
If I can get the Macro lens close enough to see them I'll take some pics Mon. or Tues. Otherwise, if you can get a copy of the magazine it shows everything & the magnet co. to buy from.
K&J Magnetics, inc. at; kjmagnetics.com is the place.
If you need the part# for the 1's for HO scale I'll post them later. You can use them on most scales.
