This item of tooling shown fitted in photo 1 was made for a number of reasons, quite apart from its obvious usefulness in working to precise lengths and depths, which can be pre-set. It can be used in conjunction with slip gauges, or on its own within the capacity of its own micrometer, which has a 1in. range. One of my reasons for making the stop was simply to machine a relatively long fine pitch thread. Prior to having the bed and saddle reconditioned at 'Myford', I generally found that due to wear and tear on the bed and slides, parts which were intended to end up parallel, always had a slight taper giving rise to problems of fit when these parts were assembled. The threads machined in this little item, fitted perfectly over the entire length without any discernible slack or backlash, which gave me a feeling of satisfaction and a new found confidence in the accuracy of the machine.
