I'm about to embark on removing all my lines from the chassis and am in the mood to rebuild them all from new components.

Any tips and tricks would be helpful about now so that I don't waste time and money, I'm not really fussed if I go to original materials if newer and better techniques are available at a reasonable cost.

What experience/dramas have you had that you can pass on to a young buck who will do this for the first time?

I've got access to a flaring tool kit so that's covered, but as for bending lines what's the best method?
