In this build series, I am working with Cliff Hall, a toolmaker from New Zealand. Cliff has invented a thread milling attachment for a knee mill that allows for cutting both internal and external threads of both metric and imperial pitches. It can be mounted on the rear edge of the XY table of a Bridgeport style mill and it is entirely manually operated. In this episode:
* How the headstock sliding parts work.
* Machining the main slide plate rebates and flycutting the stock.
* Machining the matching stepped guides.
* Machining the base plate and a trial assembly
