I'm missing the point too, as to were the tools used are needed and why?

I think what Dick did there was cut a hole in some pipe, then expanded it and made a flanged joint, So in effect it saves cutting and slipping a tee in,
is that right Dick ?

It was a task in the city and guilds course way back in the early 70s.
It's one of those things that you had to do in collage plumbing - but never do it in real plumbing.
Tappy,

I used to do a similar thing in the 60's/70's, when you went into a house to fit a washing machine and the pipes under the sink was lead, I'd drill a small hole in the lead pipe and flange it out and solder 10mm copper pipe in it, It was a quick way to do a washing machine without renewing the lead pipes  |

Thanks Tom. Seen it done with a special tool before, but wondered how it worked with the expander. After that tee, you deserve a tea. Or something stronger.

Thanks Tom almost exactly how I did it👍👍👍👍 I used a step drill(as shown in my photo), the expanders as you used them, where we differed was as follows; I put a dimple in the 15mm as a pipe stop, well in fact I used a Kingley Drift tool, this was used for Kingley Type B compress fittings, it formed a complete internal ring on the tube & no olive was required to form the Type B compression joint. A set of Conex Oyster pliers could also be used for the dimples. Lastly I used a copper sulphate bracing rod & MAPP Gas Torch to make the joint. Anyone got any further questions, please write them on a £50 note & post it to the following address; Sir Richard Puller MBE Puller Towers Bothwell Glasgow You’ll receive a swift response in a couple of years👍👍 |

your welcome Dick and, I've just posted my £50 to that address, I hope it gets there, I must say its a testament to the Scottish post, The English postmen would steal it and say it got lost, So if it does't get there in the couple of years deadline date, you'll know why,  |

a further tip from plumberboy who has also done one at home and sent me a picture of it, he says, the small you drill the hole, the better collar you get, Attachment Deleted |

a further tip from plumberboy who has also done one at home and sent me a picture of it, he says, the small you drill the hole, the better collar you get, Nice one PB, looking good!!! Totally agree the tee collar/socket needs to be as strong & as big as possible. The reason I used a copper phosphate rod is also for strength. I think there’s another thread on brazing with these?? Very simple, just get everything hot enough & cherry red. The rod will then flow & form a solid joint. Back in the day we’d use a Oxy/Acetylene Torch, but MAPP Gas gets it hot enough. It’s a cheap/easy way to tee into larger diameter copper tube >28mm, 35mm etc. I had a Rothy Tee extractor but sold it as I never used it. We’d ‘tee in’ & valve on big jobs, Hotels, Skools etc. Get it lagged before the COW spotted it 😜😜😜 Oh, one last wee point to any viewers, particularly new viewers. Tips & methods like this are ‘on site’ projects, neither Tom or I have fancy tools, vices etc etc like all these other YouTube tozzers, this is keeping it real. Tools for only a few quid & can be done by anyone. Thanks for viewing & thanks as always to Tom👍 |
