Thanks for your input, Jürgen!
Your thoughts on suspension make sense and I will add some kind of
elastomer suspension to the plan.
This annealing stuff sounds a bit risky. I made a brief search on the
Internet and it seems that pre-heated alloy should not be annealed. So
how does one know what alloy has been pre-heated? But honestly I know
nothing about the subject apart from what I read. I think my plan A
will be to buy some sort of tapered roll bearings and with the help of
the building plan to the Flevo Racer make a steering head. Using a
Flevo's type of head would increase ground clearance on the baby
python. If that fails or becomes to costly I consider buying one. But
holy shit! What if I weld this brand new thing kaputt? Well, after
weeping I will retreat to plan B which is ... bending the alloy cranks.
I spent some time looking at the Airbike pics you have uploaded on the
net. I like the Airbike a lot. I suppose they are almost impossible to
come by these days, aren't they?
Ok, back to drawing.
