STUMPED: tapered oval spoke

 From:  twofoot

Hi folks. I need to create a tapered oval spoke shape to complete this pattern for a steam train wheel pattern. See oval shapes with magenta arrows pointing to their respective positions.

Any suggestions? I cannot get it to form a solid that can be boolean unioned to create a single piece to send off to the foundry.

Thanks!

Chris
