PenrithBeacon Posted August 29, 2018 Share Posted August 29, 2018 I have installed some ‘Neodymium & Samarium Cobalt’ magnets for S&W couplings but they seem to be having the effect of slowing down or even stopping the locos motors. Does anybody please have a recommendation for magnets for S&Ws which can be located between sleepers? Thanks Link to post Share on other sites More sharing options...
mdh1950 Posted August 29, 2018 Share Posted August 29, 2018 I suggest magnets from Magnet Expert Ltd (www.first4magnets.com). They are 10 x 5 x 1mm thick N42 Neodymium Magnets with a pull of 0.6kg (North) - reference no. F1051NA-20. They cost £6.64 for 20 including 1st Class P&P. They work successfully with S&W couplings on Tony Wright's Little Bytham. Michael Link to post Share on other sites More sharing options...

PenrithBeacon Posted August 30, 2018 Author Share Posted August 30, 2018 What is wrong with the S&W permanent magnets?I believe the S&W have to be installed before the track is laid, I'm modifying an existing layout, but thanks for the suggestion.

darren01 Posted August 30, 2018 Share Posted August 30, 2018 I gave up using magnets under the track and move to electromagnet, got fed up with wagon and coaches parting if the loco jerked just a little. Link to post Share on other sites More sharing options...
sdw7300 Posted August 30, 2018 Share Posted August 30, 2018 I used some 3mm dia, 10mm long N52 magnets (admittedly for the staple glued to tension lock method of uncoupling rather than S&W). The advantage being you can drill a 3mm hole between the sleepers, push in the magnet and re-ballast over the top and they're invisible - just make sure you remember where you installed them! A couple of photo's on my test plank here. I've not seen any affect on motors / axles etc. Link to post Share on other sites More sharing options...
dasatcopthorne Posted September 1, 2018 Share Posted September 1, 2018 I had to install magnets after track laying. I obtained a 'experimenting set' from one of the well known neo suppliers. After testing and finding the right one I glued them underneath the baseboard. Get the correct ones and they work well without disturbing the track. You can also move them if incorrectly placed.

PenrithBeacon Posted September 1, 2018 Author Share Posted September 1, 2018 I have resolved this problem now. The ballasting of the track needs some attention (perhaps a lot actually). I'm now thinking about how to make the location of the magnets visible after re-ballasting; perhaps a different colour of ballast or some static grass, either will do. Thanks to all who have contributed. Link to post Share on other sites More sharing options...

PenrithBeacon Posted September 5, 2018 Author Share Posted September 5, 2018 Pose a figure (a shunter would be ideal) or a piece of equipment/junk next to the uncoupler.As there are four magnets on a shunting plank I think the layout would be a little over populated!

RMweb Gold Stubby47 Posted September 5, 2018 RMweb Gold Share Posted September 5, 2018 (edited) I added a spot of yellow/mustard paint to the end of the sleepers. These line up with where the buffer needs to be. The spots are only 'visible' if you know where to look, otherwise they just blend in.

At the moment I don't use magnet uncoupling but as I am building a new shunting layout it makes sense to put magnets in now at track lay stage. Newbies question; will these be correct for any magnetic coupling option I might pick in the future? Link to post Share on other sites More sharing options...

Does anybody please have a recommendation for magnets for S&Ws which can be located between sleepers? Thanks On my layout, the magnets have been cut in half and placed vertically. Strong enough when you ‘hover’ over them, but generally have no effect when you run the train over themEdit: should have said that these are the S&W magnets from Wizard.

Newbies question; will these be correct for any magnetic coupling option I might pick in the future? Hi, Probably not - although I've only used Spratt and Winkle up to now. Probably not correct also for coupling systems that use electromagnets. Best to check. As to future coupling options that happen not to have been invented yet who can tell. I'm hoping to fit my DCC EMUs and DEMUs with DCC operated Buckeye couplings. Regards Nick Link to post Share on other sites More sharing options...

[/color] For use with S&W does one need North or South polarity ones? Assume the difference is which side the stickyness is on?? Ta Ralf Link to post Share on other sites More sharing options...
