How to do wiped joint in lead waste pipe?

[Danfoto]

I'm just old enough to remember watching an old boy replace a lead trap on a lead kitchen sink waste with a new lead trap and was trying to explain the procedure to The Lady Wife. Two problems though - I can't remember exactly how wiped joints were done, and neither can I remember what the material (cloth) was with which they were wiped.

There doesn't seem to be anything on YouTube, so does anybody know of a video online showing the process, or else something like step-by-step diagrams?

Cheers ecowarm. Moleskin's the stuff which has a short pile on one side isn't it? Like what some old boys out in the sticks use to have trousers made of?

And well done with that video. I mush have been using all the wrong search terms

We used tallow as a kind of flux a shave hook for cleaning the pipe, a turnpin for opening the end of pipe and I used to have a double ended clamp for holding the pipes in different angles but can't remember if it had a special name, must have inhalled to many lead fumes

Hmm! Yes ecowarm is about right we did the same.

The thing with waste pipes though was that the lead was very thin and required you to have good heat control i.e not playing the blowlamp on the job to long or you burnt holes in the pipe. You could use either standard wiped joints or finger joints. Usually you aimed to tin the pipe and the trap first then solder them together. I suppose its one of those jobs your better showing how to do than explaining.

the finger joints you refer to were called scotch or welch joints round here. I hope that is not racist in any way, im talking over 30yrs ago

We called them finger joints in the Merseyside area.
