Here I start on a old tractor seat with some lines to help me get the final shape.
I cut out the middle section in the seat because it looks bad. Then I start stretching the front of the seatpan.
Welded the new plate in place while i formed the seat pan to fit it better and also to get a better shape for the ass. The seats that I make are built for loong riding trips. You can se an uncut seatpan on the side.
The shape is comming together
Here the seatpan is ready for mouting on the bike, will post pics of that.
