Hi Dirk >>I see you do not use any ribs to stiffen up the seat, does it bend while riding? For while I ride only few meters and I didn?t fell anything. Maybe it will be happend when I need to up hill . I put two reinforces ( picture 6 in the site). One of them in the lower part of the seat and the other in the half part of back seat. And how heavy would you reckon that seat is? Today I buy an electronic scale and I will weight the seat and the completely Python. It has moreless 8 to 10 mm of tickness and has 8 layers of fiberglas ( resin + yarn) Joao Preichardt Curitiba Brazil John Now I put more pictures about the manufacturing process of my fiberglass seat in the site below http://www.geocities.com/joao.preichardt/seat.html João Preichardt http://www.geocities.com/joao.preichardt/index.html -----Mensagem original----- De: python-bounce@xxxxxxxxxxxxx [mailto:python-bounce@xxxxxxxxxxxxx] Em nome de John Lewis Enviada em: segunda-feira, 14 de agosto de 2006 22:44 Para: python@xxxxxxxxxxxxx Assunto: [python] Re: RES: New to List joao ricardo boff preichardt wrote: Mr. Lewis I had a similar problem like short legs... Hello joao, Thank you for your reply. No need to call me Mr Lewis. Please call me John. My in seam length is 76cm. I will be using Jurgen's site today and doing measurements to see what will fit. Then I will start work on my Python. I looked at your site. Interesting. I hope you will let us know how your learning to ride progresses. The fibreglass seat you made looks nice. Where did you get the pattern for the mould?
