Hi All
I have seen a lot of lathe centre height setting gauges. (which I might add are nicely made) I usually set my tools against the revolving centre or dead centre from the tailstock. If I need to set a tool half way in to a job which is supported by the tailstock I use the following quick fix. I use a steel rule and simply set this between the work piece and the tool to be set. If the rule leans forward the tool is to high and if the rule leans back to low. So, when the rule is upright the tool is on centre height and therefore, the cutting edge must be at a 90-degree tangent to the centre line/height of the machine. Simply and very quick.
