QUOTE (Brian Kirby @ 28 Feb 2009, 13:24) <{POST_SNAPBACK}>It works best on these Bachmann couplings, because luckily, they use hooks made from non-ferrous alloy. All the other makes of tension-lock coupling (i.e. Hornby, Dapol, Airfix, Lima and even Heljan) use steel hooks that can become magnetized and then stick together.

Very interesting idea Brian - thanks.

Just a thought. If some form of insulation was placed between the staple and the hook (plasticard) and the whole assembly glued not crimped or soldered, do you think this would prevent the hook becoming magnetised, thereby allowing its use with Hornby, Dapol, etc?

Yes that should eliminate the magnetized hook problem on steel couplings, like Hornby, etc. I was thinking of black rubber/pvc (steady chaps) sleeving, rather like when you strip the appropriate thickness of electrical wire. The round wire insulation should stretch around the flat dropper shape. Then crimp and glue the staple to the insulation. Use black insulation, so as to make it as inconspicuous as possible.

Sounds like 'heatshrink' would do the job better and, being black, would be inconspicuous...
