I came up an idea how to make Coker wheel sturdy sideways without
widening the hub. Add a wide (as wide as the hub) metal circular
stripe (24" diameter or less) in the wheel and respoke the wheel so
that the spokes are connected opposite sides of the stripe as in the
hub. That would need a bit longer spokes. That would effectively widen
the hub more than twice or does it?
Mika, is this stripe in the same concentric plane as the inside of the rim (where the spokes attach)? Or is it perpendicular to the the inside of the rim (like a disc brake on a motorcycle wheel)? Either way I visualize it, I don’t get how it “widens” the hub… ? Kinda sounds like it’d be really hard to true. I second the motion for a diagram (please:) ).
Thanks, Mika! I see, the stripe is in the same concentric plane as the inside of the rim. Are there two sets of spokes (inner and outer), or do are they single spokes running from the hub, through the “stripe”, and to the rim? That angle looks pretty severe. I don’t know if the spokes could take a bend like that and still pretend to be rigid. Now, maybe if they were elastic spokes …
Anyway, looks like a really hard wheel to true. Anybody with 3D CAD wanna try this out?
