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
 
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)
 
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.
 
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.
 
I agree pipe was softer but was never able to bend 28 without annealing, but then never had porridge for breakfast!
 
When I was a lad.............................................................. bending springs and socket formers hardly used any fittings only tees..................................................... the good old days
 
those were the days my friend, we thought they'd never end, we'd sing and dance forever and a day,we'd fight and never lose. those were the days,
oh yes those were the days :coolgleamA::carolers:
