with lead burning, I'm hoping it works like welding, where a mentally
hot small flame does the work in a very localised fashion.

I had a small split on one corner of a lead cover over some pipe ducting
which was easily accessible (being on a roof terrace) so decided to have a
go and got good results using ordinary elctronics leaded multicore and a
small 'jewellers' butane blowlamp. I practised on some scrap first. Lead
isn't that good a conductor of heat. But you'd need a still day for this
to work easily.


Hi Dave

That's interesting... That would mean that soft soldering (aka the way lead
pipes were joined) would also work. For this application, I think a few
tacks of soft solder would be more than sufficient.

Now I'm going to walk to the plumber's merchant and ask for a stick of
plumber's metal, tallow and a moleskin just to see their reaction ;-




No, perhaps not, I'll look on t'internet as usual...

But you did give me an idea - soldering would be safer than lead burning
(less chance of unwanted holes in the roof).

Cheers
