Boiler Leaks

To cure the small leaks in a boiler,Stan Bray suggests that the holes be drilled and filled with a tight fitting plug where possible and although soft solder is mentioned,he sounds as if this is not an ideal solution:Martin Evans book on model boilers,states that soft solder can be used but,it must not be the ordinary plumbers grade.Henry Greenly’s book “Model Engineering” mentions using oatmeal (within reason).How is this used,is it mixed with the water to be used to fill the boiler and then heated-will oatmeal used to make porridge do the job? This method reminds me of the old trick of putting an egg in a leaky car radiator.

In an (oldish catalogue) Blackgates Engineering list a lead solder melting at 296 degrees centigrade is this suitable for use on a copper boiler which is already soldered with a 610-620 degree melting range silver solder.Work on my engine is at a standstill so any information will be much appreciated

Thanks for taking the time to reply will most likely use Consol.Not in touch with a boiler inspector unfortunately.
Jens Eirik Skogstad An Interesting fact,horse dung appears to have been very useful item in the pastie;bell moulds,explosives not to mention soil treatment and rose mulch.If I find a 1in scale horse I may try that method.

I can no reason for the need to further silver soldering so as mentioned above it looks like
