Soldering Stainless Steel terminal in a Wall clock movement.

[iffee]

I have housed a single White LED flash light cicuit in a salvaged clock movment. It has a nice one AA cell holder. I have problem soldering the stainless steel terminals of the AA cell holder. Normal 60/40 SN/PB solder does't do the job. I have many such salavaged clock movements and want to house small electronic projects requiring only one AA size battery.

Note in my country no other special solder other than 60/40 available.

In that case you will have to source it from another country!, you need special solder to solder stainless steel - any decent component supplier should stock it.

stainless steel terminals of the AA cell holder.

Are you sure these are stainless steel ? not just chrome plated tin/brass/crap ?
All the battery holders I have seen use something much cheaper than Stainless - which is a b#tch to machine :evil:
Maybe you just need more heat (use some sandpaper first to roughen the surface) a bit of brass about a half-inch square takes a lot of heating up.
