And so by popular request...
I cobbled together some paint-cans, a set of wheel chocks and an axle-stand and I managed to get the various things to stay still long enough to take a picture of it in a simulated "together" formation.
The BB shell axle is 68cm from the seat mount (as per the other Python). The BB-shell is "just" the other side of the wheel's axle.
I could not move the wheel closer to the seat as the main-keel was touching the tyre; but if I chop some of that off the wheel can come closer and the BB further forwards around the wheel to a more 1:30 PM position.
You can see that the front frame members I have made will be able to be secured under the main keel on a Pivot that will be mounted to a downward & forward pointing spar welded on the underside of the main keel.
A fold-down set of 3 "mounting steps" will be required in order to get on the seat....Of Course!
As you can probably see, the seat height is at or just below the 24" wheel height.
That's all for now, I'm a bit tired today for some reason.
