may i´m wrong, but you can use your earlier created curves to get what you want?

look at the pictures

Not quite ... look at those spokes a little closer, they have a ridge on the back ...

Oh I guess those shapes don't line up correctly ...

Ah, ok...

i try it again... with a little "dirty" trick.... I extrude the faces of object 1... so i can substract it from object 2...
(some boolean won´t do it ... i mirror the object... than the boolean works?)
whatever... is that what you wanna get?

best regards, tijai

yeah thats it ;) but I think I'm on the wrong track ... I was trying to get this kind of rim
but the filleting operation doesn't work ... will try something else ...
