|Here we have (from the bottom clockwise) the seat-tube locator, the bottom bracket shell mount, the headtube mount and the drop-out mount.|
|Close up view of the drop-out mount.|
|Close up view of the headtube tooling.|
I set the centre of the bottom bracket and this formed the datum for the location of all of the other aspects of the frame.
Next was to set the sliding drop-outs to horiontal and the rest was easy!
