@ 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
