If you are going to try this method, I would suggest Woods Metal, available from Reeves ( possibly other suppliers too?), which melts in boiling water. It sets solid, like lead, but it's far easier to 'handle'. Once used, just keep it safe for re-use whenever you need it. Pipe benders are used when piping needs to bend to fit around an obstacle, or through a gap. Bespoke automakers often use them to bend exhaust pipes and other automotive accessories into shape. When choosing a pipe bender, you'll be faced with a few options. Many pipe benders or tube bender kits will be designed for a specific job or application, so choose wisely.

As the water flows down the "straight" all of a sudden it encounters a tight, right angled bend. Because the bend is so tight the water simply hits the side of the fitting before going round the corner.

If a pipe can be bent to do the job, it is impossible for it to leak. If it has fittings in the run, it certainly can! How to Bend Copper Pipe Pipe springs can be used in pipes up to 22mm diameter but bending a 22mm pipe with a spring is a herculean task which none of us would attempt.

They're designed for reliability, durability, and strength, with many professionals getting decades of use from their tube bender kits.It isn't too good for very tight radii,I resorted to the groove in a piece of bar method mentioned above when making new cylinder drain pipework. Pipe benders are used to bend metal pipes - such as stainless steel and copper pipes - to form a range of curves and angles. Pipe benders are a refreshingly simple tool. Unlike most modern hand tools, pipe benders don't require any power whatsoever. This makes them great for remote working, or for working near any pipes that don't have a power source nearby. Another method is to machine a groove in a piece of bar, the groove width being the diameter of the pipe and the inside diameter to suit the radius of the bend. The pipe's simply bent around in the groove. I was talking about this subject of bending small pipes only yesterday to an engineering friend. He was at the Harrogate ME show and was told that one of the ways to do it, is to anneal the copper pipe and then to fill it with molten lead. Do the bending and then melt out the lead. This way will prevent collapse and kinking of the pipe. Seems like a good idea. I will put this to the test myself when I get to my pipe bending bits. Hope this idea will help you.
