[python] Prothon seat/stearing pivot

Hello Jürgen and all the other readers,

sorry that it took me some times to come back to your question about the 
stearing pivot but i needed some time to find the right words (of course in my 
dictionary).
The axle of my stearing pivot is a 18cm long piece of threaded rod, 24mm diam. 
A friend helped me to turn the end-parts to 18mm. This ends are pluged in heavy 
duty axle bearing wich are connected with the aluminium/wood sandwich that form 
the middle part of my prothon. 
I used a threaded rod so i could use nuts to get the necessary withd to fold 
the 5mm front aluminiumsheet around it and to have some strong paralel points 
to fix it with some 10mm bolts through the axle. I know this construction is 
not really lightweight (2-3kg?) but it works very well, and you could put a car 
on it ;). Im sure it can be done a lot more lighter, but i wanted somethings 
very stable that allows me to decompose the forces to a maximum into the 
front-part. -my weight is between 95 and 100kg and i allready had about one 
million falls. The next Python will certainly become more filigran...
The rest of the front wasn´t so difficult, Wolfgang Bion sold me a aluminium 
BB-Shell that is hold in place with some screws, the rest was cutted with 
simple holesaws and a angle grinder.
I can send some picture if someone minds...

I have tried to ride my Python today and i must say that the seat seams really 
to be my weakest point, i will try to build a new one before easter, so i hope 
to be able to ride a little more then 10meters till the Spezi- I am still 
hoping to meet one or two more Pythonauts out there. I believe this could be 
helpfull to find out how bad or how good the geometry is.

Tschüß Jérémy
