I am trying to extrude sketch 3 to the Extrusion 1 but keep getting Error....is this the wrong way to create?
Also the Extrusion 2 cut out for centre hole does not seem completely round.....
Could this part be made using better techniques.....how can i create this part with better steps

Your error isn't actually from the extrusion - it's caused by the sketch. You have projected geometry from your inner diameter of the previous extrusion. For some reason, it is seeing the two resulting projected arcs as a self-intersecting profile.
I don't see anything overlapping, so I'm not quite sure why it's doing that. But if you set those two arcs to be construction geometry, the problem goes away.
When you extrude your sketch, select "To" in the Extents Box, then select the face of Extrusion 3.
