Geometry Nodes

I’m trying to reproduce the extrude trick of the screw modifier with geometry nodes but I can’t figure out how to flip all the faces to point their normals in the right direction.

If I use the geometry from the screw modifier object (without the solidify modifier) I can sort of get it to work except the face extrusion along normals doesn’t behave as well as the solidify modifier.

Is there any work being done towards the goal of accurately being able to reproduce the results of the various modifiers?
