Using steel rule and 90-degree tangent for centre height tool setting Quick and easy

Congratulations
Finally, Someone has remembered the simplest and possibly best method of locating a lathe tool on center.
I have quite enjoyed all the clamor of building "Hight Gages" to do the job when the absolute simplest and best method of locating was using a thin flat piece of metal against the work or something on the lathe that is always on the vertical center.

I might point out that it may be OK for setting tools used on the exterior of the workpiece but it isn't very useful for setting boring bars.
