I'd sort of thought the radius of the bend a pipe bender makes is about the tightest that is safe for a pipe bent cold? And if you need tighter, you use elbows or bends? The great beauty of a bender, of course, is that it can be used near anywhere in the tube.

But before I had a bender I tried doing the sort of tight bend you get with those, and couldn't retrieve the spring. -- *Support bacteria - they're the only culture some people have * Dave Plowman London SW To e-mail, change noise into sound. |

Not having a pipe bender for 28mm copper tube, I fell back to using traditional methods. Anneal the pipe only where you want it to bend, pack it full of dry sand (molten lead is another option, but a bit more messy;-). Support the pipe either side of the bend on something soft (sand bags in my case), and gently step on the pipe at the point where you want it to bend. Worked perfectly, and it only bent at the anneal point, very nicely without crumpling. Me neither, fortunately I'm not trying for a right angled bend. If I were simply trying to save on fittings I would get a pipe bender, but IMO the large radius of the curve makes tubes bent in a bender unsightly if used where they can be seen. If you have a pipe following the corner of a room, I agree. If you are referring to an offset for a radiator tail, I prefer the smooth bends of a pipe bender. Where a bend is out of sight, I'll use a pipe bender unless it makes the job much harder as it's generally fewer pipe joints, and the swept curve is lower resistance than an elbow (although not as much lower as you might guess). I'd sort of thought the radius of the bend a pipe bender makes is about the tightest that is safe for a pipe bent cold? And if you need tighter, you use elbows or bends? The great beauty of a bender, of course, is that it can be used near anywhere in the tube. Some say you can bend a right angle in the middle of the tube using a spring and retrieve it, but the one and only time I tried I couldn't. ;-) One slight drawback of a pipe bender is it can only bend with one radius (at least, I've never seen formers for larger radiuses for same size pipe). Once or twice, when I've had a pair of pipes to bend in the same plane, my geometric mind wants the nested bends to have a common centre point in space, which you can't do as the outer one would need a bending radius equal to the inner pipe's bending radius plus the pipe spacing. You could do this with a spring bender. Once I did it by using an elbow for the inner bend and pipe bender for the outer bend, but that was dictated by circumstance, not for aesthetic reasons. -- Andrew Gabriel |

Hi Doctor Evil, if you quench the tube straight away, it makes it easier to clean off the black oxide, however the annealing effect will happen anyway if you just let the tube cool. This is much slower, though. Quenching of steel, for instance, is a different matter. |

I re-open this to mention that when you bend the annealed copper, it will harden. You can anneal it again if this is a problem, however avoid "working" the metal excessively. |

How is that going to work? Copper tube was filled with it and capped off at both ends during bending. The non-compressibility of the lead prevented the tube collapsing during bending -- same effect as for dry sand. I think molten lead was used (as opposed to water, say) so the tube could be continually annealed during bending which would be impossible with any liquid which boiled below copper's annealing temperature. (I've got an old book on copper tubing which describes this, but it's currently stored in a box in different house, so this is from memory.) -- Andrew Gabriel |
