Seat drilling and mount

I drilled the holes in the carbon seat.  There is lots of different advice about how to do this on the web.  The risk is 'tearout' of the carbon fibre at the bottom of the hole.  To avoid this I used a step drill, usually used for drilling sheet metal.  This worked well and I got fairly neat holes.

The front seat mount rotates to adjust the seat angle but ther is not bacwards / forwards adjustability.  I may add this later if needed.  I used weld nuts, which provide a stop for easy location of the seat.

The rear mount will adjust using holes in the mount piece and swivels at the top to allow for angle adjustment.  The mount is offset as there is only a frame on one side.
