The petrol tank on bikes makes or breaks the look, the first one was done free hand ie, without the use of a buck, then to get better consistency we made a buck, but I forgot to photograph it, but a did do of a later one both pictured here.
free hand one.
bottom image is the centre of the buck, second from bottom tank side is made from one piece, and is for a super twin at the TT

Should I continue with images of the Centre Hub Steering bikes development?
Yes please! One day, when I'm in Tunbridge Wells, I might drop in for a cuppa! This work is so beyond anything I've done I'd love to see more!
Your welcome to, the bikes are still here, but they don’t get used now sadly, and I don’t have CNC equipment here, just, a lathe, Tig, Mig, etc etc, but for my current project CNC wouldn’t suit, it’s mostly hand work.
I'm probably going to be at Gerry's early July. I'll check back with you then?
