Lead burning/tack welding torch - boiler flue through lead roof

Isn't this what you're after?

Perhaps - although I could use a 5 degree (or zero degree) version; the roof has very little pitch.

However, this looks interesting:

Thanks for that pointer.

I've prolly got one that will do what you need

I have a friend who is a lead roofer who will be able to tell us exactly

Look forward to it - ta.

I expect "others" might bond a lead slate on with some rubber scunge - but welding seems better.

I have one of these (with a mapp gas cylinder on)

Looks like the sort of thing used here:

I expect that is what this one is, although they have the wrong photo:

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).

As this is uk.d-i-y ...

... you have to catch your own mole. ;-)

My local TP stocks all of these. But you don't need tallow or moleskin for the sort of thing you're doing. They're needed to wipe a neat finish on a joint.

I used to do plumbed joints on lead sheathed cable when I first started work (1960s) . Used a very large (2lb) copper hatchet style soldering iron heated with a paraffin blowtorch. It's quite unwieldy until you get the knack but easily handles jobs like that. Only ever did a couple as we went over to joint boxes after that thankfully.

Indeed it would.

I used to have a gas blowtorch with a soldering bit attachment that would be ideal for joining sheet lead. Had a look on the internet but there doesn't seem to be anything like it now.
