Forming tool

Hi,

I have been looking at the tutorials and I cannot figure out how to use the forming tool. I am trying to make a washer that has been bent around a cylinder (cylindrical spring washer), so I cannot just extrude a cut to give the bent profile as it will still be the wrong shape. (In plan view a washer is circular, but if bent around a cylinder it takes on an elliptical profile). It is this elliptical profile that I am interested in.

Can any one out there help, or tell me where I can find a better tutorial?

Thanks,

Eoghan.
