Is RS ‘Dispensing Solder Cream’ the answer

I have to solder, at both ends, 24 tubes 1/4" OD into the end plates of a condenser (Bolton Triple expansion engine).

Not sure how to 'tin' the plates or the tube ends in such a way as to get the 24 joints to make as I wave a torch carefully around.

I have a tube (out of date but have been raised on out-of-date food) RS 'No clean RMA dispensing solder cream' that sounds as if it might be the answer – anybody out there expereinced in it use – or have better advice?

I can answer my own question after trying the solder in cream form.

It works OK for surface mounting objects or soldering two plates together with the cream in the sandwich but it doesn't work where you need to form fillets around multiple tubes – or rather it is very difficult to apply and it is easier to use traditional flux cored wire.

Try to get some LACO soft solder flux .great for that sort of job . Its what we use to do it on the job

I have some "FRYOLUX" solder paste, and now I'm used to it, it's great. Got it from [plumber's supplies section at one of the DIY sheds. Washes off easy with a bit of washing up liquid and leaves brass sparkly.
