Lathe Tool Height Gage

[mklotz]

On my magnetic pickup tools I use aluminum foil or Saran wrap (transparent) on the one that has a built-in light. Simply unwrap in such a way as to include the gathered swarf then discard. My guess is that the thickness of aluminum foil is very uniform so it should work well shielding the base of a height gauge.

I tend to not use the magnetic base indicator holders. Long ago I made a DI-holding block for the QCTP and that handles most of the work requiring indicators.
