Extending surfaces...how?

I've got a small ABS design, predominantly a revolved partwhich needs to have four stabilising legs attached.

I initially created the legs on the right plane, then offset thatplane either side, extracted the sketch then created bodies, thenfinally suppressed the initial legs. However, as the legs areoffset from the centre, none of them are now attached to the mainbody itself.

How do I extend the face highlighted in this image:



so all the legs merge into the main body?SolidworksSurfacing
