bending pipes

[dweeble]

I have a hilmor bender and having not used it for a while i cant remember the measurements. For two 90 degree bends with say 200 centres (15mm tube) i used to bend the first one then measure 200, then take 70mm off and put that mark on the edge of the former and bend it. There is a name for this technique but i cant remember it and i cant remember the measurements for other angles or for 22mm tube. Can someone let me know these measurements or provide a link for them (or even the technique name would be a start). Ta in advance.
