Rippled or not rippled with a bending spring is mainly a property of the copper. "Old" copper hardens and is more likely to ripple. Newer copper is softer and more malleable and less likely to ripple. (You can soften old pipe by heating then cooling. Also it is important to carefull inspect the spring along the length where the bending will take place. Often when removing the spring from a bend it can get stretched if not rotated anticlockwise when removing. A stretched spring (with open coils0 will cause rippled in the pipe. Ripples caused in a pipe bender is mainly due to friction. This can be overcome by using talcum poweder on the sliding surfaces as a lubricant. Nice video, thanks.
Thanks for the extra tips.
Excellent comment diymostthings! that is a good caution to apply. An stretched spring is useless! I've heard of greasing, but talcum would probably be better, and perhaps, withstand the heat of the just annealed tube.
So, essentially the wrong way is the right way......and the right way is the wrong way! Thanks for the tip!
Pretty good, I’m impressed. Don’t worry about it mate , nothing ever quite works well all the time. All we can do is to try our best and hopefully things will turn out well. Good advice, thank you
Very true
It's videos like this that save the day. I thought the spring bender went on the outside.....daa! Thanks!
+Marc Del ME too !!
+Tony R and me duh
Marc Del you can get external and internal bending springs so your still correct
Me too
There are BOTH Inside and Outside types of bending springs. Those with an end that resembles a little funnel are the EXTERNAL type, and those like the one in this video, have one or both ends slightly tapered, to make them easier to go INTO the tubing. Those internal springs usually have a ring on the end, to tie a cord and make it easier to pull them out of the tubing.
Yes isnt it just typical after 40 years of bending copper pipe, that for the first time in front of the camera the tube decides not to crease up on the bend.O`well it just goes to show ya.Take no notice of me just put the spring in and bend.
i thought you would have mentioned to get a spring out of a pulled bend,you twist the end of the spring to the right.this reduces the outside diameter of the spring and it slides out.
I have to admit I have never tried heating it up first (might be a bit hot when I go to bend it on my knee) In theory it should work . I have always found that the older the copper tube the easier it is to bend without ripples . When it is new and shiny that seems to be when the ripples happen . Kind regards,
al.
Thanks for this great little inside tip, so useful and cheerily presented. Thumbs Up!
Until five minutes ago I didn't even know those springs exist, not I even know the dos and don'ts. Thanks a lot!
No problem
I had heard of them... but last week I was very surprised to learn that there is even a BRITISH STANDARD on Bending Springs!!! No joke!
Thanks for the info, dereton33:-)
I'm just about to (try to) build my own water feature/sculpture using 15mm copper pipe and driftwood and I was wondering how pipes are bent, so this is really useful to know :-)
Mr Dereton, you Sir are a top man. Love these vids mate, you are Great Briton, and old guys rule!
Ha ha thanks James
Thanks, it's clear illustration 🙏
You're welcome 😊
Thanks for the tutorial. Things happen when the record button is pressed that don't ordinarily happen. It's happened to me many times.
Yes it always seems to.
Good tips re. sawing the end to get the spring in and over bending the pipe so you can release the spring...ta.
Not sure if that is allowed in the US per code. Bending the pipe allegedly weakens the walls of the pipe at the point of bending. Good tip in a pinch though.
That's ok Baz.
Regards,
al.
Thankyou...that was very informative and easy to understand.
No problem
That was quite useful I had a go with one of these springs and got it stuck in the pipe, I think now I've seen this I get where I went wrong.
Typical that it goes wrong on camera but thanks for doing it anyway
adam oliver No problem adam, point a camera at anything and it goes wrong, you should see how many out takes there are, ha ha.
Be careful pulling the spring out! I know a guy that lost an eye to an apprentice pulling a spring out of a bit of plastic conduit.
very practical video. Thank you for the tip.
No problem John.
Love your videos, so informative, you should start an academy!
+Notherian Ha ha yes maybe.
Handy tip, thanks for sharing!
Thank you
You're welcome
You can also fill it with sand or salt :)
Old ways are thebest ways.
Not sure if this method will work for creating a circular piece of cooper?
dereton33: MAYBE, just maybe, the reason that the second bend did rippled is because almost all metals actually tend to harden when they are cold worked... Copper is sold in several different temper degrees, the soft copper tubing that comes coiled for gas installations is "annealed" and is very soft, so it can be deformed easily. The other common copper pipe or tube is commnly known as "rigid" or
"Hard Drawn" and is much more difficult to deform. The first bend you performed was bent in a countinuous manner, so the copper "flowed" and did not rippled. In the second bend, as you stopped several times, you possibly gave the copper a chance to harden due to the bending, so it became a little harder and rippled more. At least it is what THEORY says (and of course, we ALL know theory almost never meets reality! Best wishes.
Thanks for the info Alf.
A natural comic...fast bending works great....slow bend method produces a ripple!...lol
Your videos are always so engaging :),
The topics for your videos are on point :),
This vid of yours had me glued to the screen:),
What camera do you use to make your episodes?,
What microphone do use?
I use a panasonic lumix dmc tz60.
If your G-shock disappears, the cameraman should be the first suspect.
Thankyou 🙏🌹
You’re welcome 😊
mr . thank you just what i need to know
No problem.
thanks for sharing ,,
Thank you the pump work fine as i have release the lead switch with a magnet. The problem have got now is the brass tube connection into to the flex tube does not fit properly as the tube as been damage during binding process. Is there a tool or trick up there for that to fit properly?
No it is best to renew the flexi tube if damaged.
It is the brass tube who got some little dentes
OK I see . Renewal of the copper pipe is your best bet.
Ok i will do that!
Thank you
Is there a way to take a measurement to be 100% sure where the center of the bend is gonna be, like you can do with a bender?
No not really.
Modern copper is so thin these days spring bending is becoming a dying art mate. Even in the machine it can ripple
You are right there Paul.
Perhaps you could bend it easier by first annealing the copper by heating it to less than red hot (overheating is undesirable, but enough heat is necessary).
I've tried bending 15 mill in a pipe bender and sometimes it ripples. Is it safe to use this pipe in an installation? Thanks for all your great videos Del
Yes, it is
Thank so much for your video
N0 problem.
Hi, what’s the issue with ripples? Is it just that it’s cosmetic? Does it affect the integrity of the pipe
It does look better. It doesn't effect the integrity of the pipe.
Can cause water scouring. Erosion of the pipes.
Hi buddy, love the videos. Quick question, can you bend 22mm 90 degrees with one of these? Keep up the good work Sir.
Yes you can.
@@dereton33 Pardon me, but 22mm of hard drawn copper seems difficult to bend without annealing it first, doesn't it? Please tell us what pipe did you bend in your video, as it is difficult to appreciate the exac diameter of the pipe, and if it is of the hard variety or the soft, coiled type...
How do you get a very small dog legged bend? One that bends 45-90 degrees one way and then back again. But it has to be very small, total width i need is about 1 1/2" on 15mm pipe? Are there pipe benders with a very small circle for this? I have seen bits like this inside boilers occasionally, can't remember which ones now though.
You can buy pass over sets, but with a pipe bender you are restricted on how small a set you can make.
The million dollar question. Where do you get the spring?
Amazon.
Does it help to heat it up?
Only if you want a burnt knee.
What is the effect of spring bending on the different class of copper, 0, 1 & 2?
The thinnest ripple while the thicker copper does not.
@@dereton33 thanks
Thanks Boss!
No worries!
Can you bend 28mm this way please?
No only 15 mm and 22 mm.
Dear dareton33, ¿will this method work for 1/2" dia, M (red, wall thickness ~0.028") and L type (blue, wall thickness ~0.040") pipe (tubing) sold in US for household water supply), please? (The copper pipe I mention seems very stiff to me). I want to make a large radius bend (but just for a short distance) on both ends of a 14" to 16" piece of said copper pipe (tube). Any and all comments welcome. Thank you for making and posting this video. God Bless. tonyd\.
I would only try it on the thicker blue pipe.
@@dereton33 thank you for the reply. Better with the thicker wall tube, I see. Thank you again. Merry Christmas. God Bless. tonyd\.
Brilliant me old china...x
Cheers mate.
nice slippers are they plumbers standard health and safety issue?
trangia777 Toe tectors built in. Al.
What is the spring you used originally used for? I would like to purchase one but unsure where to start looking. Thank you.
Hi David the spring is an actual pipe bending spring and can be bought from any plumbers store.
Regards,
al.
Thank you Al
No second takes for the Limey Frank Sinatra!
One and it`s done mate.
Park life
Where u get the spring?
Amazon.
can we use 10mm spring for 15mm copper or it has to be 15mm spring for 15mm copper pipe please.
It has to be 15 mm.
£3.49 now! - that's inflation for ya ;)
You never know it might go down in the spring.
Where do you get the spring? Who sells it?
As they say never work with children, animals and copper tubing.
Ha ha so right.
Thank you
You're welcome
