Colin A Richardson Posted January 15, 2010 Share Posted January 15, 2010 Hi everyone, I am after a little advice on how to solder on to nickle silver track, the join i get never seems to hold at all well, and they are for ever comming apart, I do roughen the serface, and try to get the metal as hot as i dare, but it never seems to work that well for me. Any tips would be very welcome. Regards, Colin. Link to post Share on other sites More sharing options...
Kenton Posted January 15, 2010 Share Posted January 15, 2010 Soldering problems nearly always come down to 1 wrong solder 2 wrong flux 3 too little heat but more often than most unclean parts. You are soldering wire to track - so I assume the bottom of the track with any webbing removed. Use multicore resin fluxed solder - for electrical purposes NOT LEAD FREE Tin the wire. Tin the bottom of the track. place two parts together and melt the solder with hot iron - remove the iron and DO NOT move the parts until cooled. A 25W iron (with a CLEAN tinned tip) should be more than adequate. Nickel silver is as good as brass or copper for soldering. If it was steel rail - then that requires different flux.

davknigh Posted February 14, 2010 Share Posted February 14, 2010 Just one other thing to add to the existing good advice- good fit. If the parts are not making decent contact then the job of heating them evenly becomes that much more difficult. HTH David Link to post Share on other sites More sharing options...
RMweb Gold Oldddudders Posted February 14, 2010 RMweb Gold Share Posted February 14, 2010 As a particularly clumsy modeller, with a fine line in impatience, I can recommend Baker's Soldering Fluid as the way to get most solderable surfaces to behave as you wish. Cleaning the surfaces is important for any soldering, but I find that an initial application of Baker's, even heating it before putting the solder anywhere nearby, can make the cleaning more effective. When I first used Baker's, more than 40 years ago, it came in a tin, which the product showed every sign of trying to eat. Now it comes in neat plastic bottles, and doesn't look rusty when you tip it out! Just one caveat - do not use it in a confined space if you are asthmatic. Don't ask me how I know!

Coombe Barton Posted February 14, 2010 Share Posted February 14, 2010 Bakers Fluid from model shops tends to be expensive compared with online toolstores or plumbers, or the increasingly rare shop. Link to post Share on other sites More sharing options...
