Hi Chris,
perhaps this method may help.
After boolean union spokes to hub select the edge and join.
Add circles sized to the radii you need and sweep joined edge curve.
Trim Hub and blend.
Note when I produced the hub I rebuilt the curved section
so the surface was complete (no seam lines) this helps the blend operation.
Cheers

Barry, you are WAY better at Moi than I am. LOL

Is there any way you could show me the process step by step? This is EXACTLY what I need.

Thanks

Chris

Hi Chris,
you can just use the fillet tool as shown in the photo.
I did the collar trim to give a variable fillet as I was unable to get it with the fillet tool.
I'm basically trimming the solid with a collar produced by sweeping desired fillets.
The sweep path is the edge where spoke joins the hub.
If your still unsure post me your curves and I will mark up what's needed.
Cheers
Barry

Edit:
It's possible to do it with the fillet tool with variable fillet my problem was filleting across the seam of the hub.

Hi
have you try ONSHAPE to do the bevel ?

@ Barry-H, how did you get the sweeped circles to meet the spokes and hub at a tangent with your first technique? Or are they just roughly positioned close enough to tangential to suffice?

Hi,
the circles are snapped to the edge to be filleted.
I used 2 small circles front and back & 2 larger circles on the sides.
Then sweep the edge curve to produce the trim collar.
The blend operation produces a tangent fillet.
Hope this helps.

Ah, the sweeped circles are just to trim the part, then a blend is actually used for the fillet, ok I get it now. Thanks. At first I thought you somehow managed to sweep between the 2 different sized circles in a way that the resulting torus-like form stayed perfectly tangential to the spoke and hub all the way around the sweep...

DanC I'm glad you get it. I'm still confuzzled. LOL
