Old skool plumbing Part 1 how to bend 28mm copper with spring

[ecowarm]

28mm copper pipe and bending spring. The first thing to do do is anneal the copper.

This involves heating area to be bent to a dull red colour and either quenching or waiting untill cooled. Bend pipe around the knee carefully not applying to much pressure in one place.

The pipe may need annealing again as did here because of short pipe and not much leverage. pull bend slighty over 90 and then bend back carefully to release the spring.

Completed bend


Job done.

First two pics not loading , will try again

 

[ecowarm]

Can mods look at the first 2 pics?

 

[PlumbBobBob]

[ecowarm]

When I go to edit post the pics are there?

 

[gassafe]

all pics are fine on my comp...

 

[ecowarm]

Can you see 5 pics? GS

 

[gassafe]

No there are only 3 pics i thought??

 

[markfxy]

when you've bent the copper tube dont put it down and go for a cup of tea come back and try to hacksaw the tube with spring still inside only a complete numpty would do that:blush5:

Not something you would do is it Mark?

I've had too many years and aching knees to want to bend pipe again with a spring. Tripod bender for me every time, and yes I'm old skool!

 

[ecowarm]

got pics sorted

Just thought it would be interesting to show how we used to do it

 

[Guest123]

Yes it is interesting and a very good post, that will show the young uns how it was and still can be done.

Maybe in part 2 you could show a lead and rope run joint in cast iron? This has come up quite a few times on this forum.

 

[ecowarm]

More old skool to follow, lead burning next. Maybe video but I think that needs youtube?

 

[Guest123]

Still do a lot of lead burning. Today it was T-Pren joints. A link to youtube would be great for showing how to leadburn.

T Pren. How much of a mark up did BLM make when they cut the rolls to 3m and put the flap over? 6m roll became a 3m for the same money with a bit code 3 flap.

I fitted so much of that stuff about 12 /14 years ago (200 odd 6m rolls) i even had the (ex)wife cutting and burning one side onto the sheets. After a few weekends of teaching her he was good at a lap joint and cheap too. She could do 6 before getting on with the housework :lol:

 

[Guest123]

At least Tamz has the peckin order sorted. Get the missus to burn a few lead covers and then let her to get on with her womans work.

 

[SimonJohns]

Great advice. This is something I would like to be a part of. Just can't think of things to do

Well done

 

[tamz]

She was doing nothing much else at the time. The weans were at the school, Jeremy Kyle had not been heard of, she had lost her ha'penny and needed a bit something to fill her days so i put her to work with a litre of milk :lol:

Never pick up the hoover is a good place to start:lol:

On a serious note there is /are lots of things us older guys know how to do that are being lost to the trade. Would the young ones even know what a hank of hemp looks like or where to buy rope yarn. I don't know how to do videos but if i can think of something to put into pictures i will.

How old do you think I am Tamz?

I had to err on the cautious side since she was the mother of my weans. Couldn't have her forgetting what days their clubs were on :lol:

I know you are just a pup Simon but you have a good head on you.

How to joint cast iron.

If you don't have a proper caulking tool. cut a 6 inch bit of copper, bash about 3 inches flat and the round bit is your handle.

Here is a good quick way to do perfect overcloaks for anyone who is doing leadwork. The guy who taught me this method, when he retired gave me a set of books and this is from one of them dated 1907
There are 6 books in total but i only have 2 of them. Full of useful and past skills and tips.The others i'll need to get my lass to steal out the attic of the ex


.
It is spit in 2 as it was on 2 different pages and it is too late for me to figure out how to combine them.

This volume 1 of the series of books is available on the net if anyone is interested

:ihih:the earlier posts about not get the pictures to show was a cleverly staged plan to dupe us as to your real skills with the camera editing. What we have here is a 15mm pipe and spring, shown next to a mini burner for jewellery work, and a pocket sized square.:ihih:

sorry, couldn't resist the temptation.
Thanks for the post, I have a 28mm spring, I would now feel confident to use it

 

[tamz]

I've got an 1¼" one lying around somewhere. If you want to have a go of it you can have it (pipe is a lot harder and thinner than it once was)

 

[Dannypipe]

When annealing pipe, I was always taught that you heat till red hot, then letter it cool naturally.

Quenching it in water cools it quickly and I was always taught this is how you undertake tempering of an alloy.

In fairness, I haven't much experience in this subject.....but just saying what I was told.

Good post by the way eco.

 

[tamz]

Annealing and cooling copper make little difference to the hardness. Heat, cool, pull. You can do 1" without annealing if you take your time and have good knees but the quality of the pipe is not what it once was.

 

[ecowarm]

I agree pipe was softer but was never able to bend 28 without annealing, but then never had porridge for breakfast!
