Experimaental SWB

This was an experiment that very nearly worked first time.
It had a few new things I tried including my first attempt at building a shell seat.
The frame was loosely styled on the legendary Lightning P38.
The frame was taken from an old ladies tenspeed (the type with twin top tubes) and the seat post was cut below the top tubes leaving the section visible below the seat.
This allowed for the down tube and chainstays to be removed from the bottom bracket... these were shaped and bent up to be re-attached to the seat tube ( Note: the down tube needed to be cut and shaped at the head tube end to meet), the seat tube above the top tubes was removed.
By bending the seat stays up it was possible to use them for the seat brace... another set of twin top tubes was fitted between the seat stays and the top tubes making a support for the seat and securing the seat stays at the top end.
The bike has since been altered from the set up in the pic... the seat is reclined further and the steering was altered to compensate for the more laid back style.
I am not finished with this bike and will make further alterations to the frame to tidy up a few of the minor problems that still exist.
Although heavier than the bike that inspired it the performance wasn't too bad in a recreational riding sense and I look forward to finishing this project and using the bike as an all round commuter and fun machine.
