Colchester lathes have what I consider an awkward design feature, in that the change gears are not a round bore with a key, but an 8 tooth spline. In the factory they would be broached with a purpose made (all at once) broach, but in the home workshop that is tooling that we don't have.
John Stevenson (MBE) showed a technique once and here I have copied it to achieve that special spline.
