Hi Chris,
I noticed tapers on the hub and the inner wall of the outside rim and understand a draft for casting. However, i did not "remove a taper".....

I did view the spokes as a "straight extrude in z" and thats what i did in the video, but thats not the issue i demonstrated in the video. I will re-examine the spokes draft angle and redo the vid if necessary. The issue is with regard to non planar curves being used to generate the solids.
