All right. I just got home from a wondermuss trip in Millicent (The Bus) and I promptly celebrated by having two beers for lunch, so....
I've been designing something the whole way home from Camarrillo. See... I am now the custodian of yet another Kinetic pedal vehicle, and this one is definitely going to Burning Man with me this year. It has a couple of mechanical "issues", which is why the owner let me take it home to see what I might be able to do with it.
Well, it's another four-wheel vehicle with no suspension. Gull dommit, even Henry Ford, the fool, figured out that a four-legged dining table would rock on two legs if the floor was uneven, but a three-legged milking stool always leveled itself.
So I'm considering the standard fix: Turn the #$%^&* thing into a trike.
This chassis happens to have a lot of ground clearance in the middle of the front -- perfect for a single front wheel.
Mounting it is a different matter. I would like to avoid permanent alterations (or butchering) to the professionally fabricated aluminum frame. So I'm thinking "use the existing mounting points".
Now.... Eventually, I'm going to take photos of what I have to work with. But meanwhile, we can simply think back to the "hub-less" motorcycle wheels that some of us posted photos of on this thread (or previous years' editions). The front spindles on this Thing (The Beach Party Buggy
, actually) are bolted on. I'm thinking of fabricating a cross-member that bolts to these hard points. Then the cross-member would have a pivot point for the steering in the middle -- a king pin.
The problem, of course, is that with the steering spindle attached on both sides, there is no place for wheel spokes to go. So the wheel bearing(s) need to go around the outside of the steering mechanism. A "Lazy Susan" kind'a bearing, sort'a. In fact, I could probably rig up a rolling prototype with a $5 Lazy Susan bearing or two from the nearest hardware store.
But for a week on the Playa, and a career in Kinetic Sculpture Racing, we need something better.
) I have it all designed in my mind. A ball bearing, where one of the races is split in half for assembly and servicing. The inner race attaches to the hub, and the outer race attaches to the wheel. Diameter... somewhere around 10 inches. Tons of machine work, then tempering of the races.
Or.... Maybe something exists that can be adapted? On the cheap, I mean?
