I'm using a Iscar threading shank with a three sided cutter. And a threading gauge or two are available.
Consider a 1/2" bar with a square end. It's in a lathe collet. Line up the tool shank to be 90 degrees to the bar. No gauge used, just straight edges.
The contact area at the edge of the bar against the shank is long and easy to adjust on.
Is this a good practice - leaving the threading gauge in the tool box.
I hate trying to keep a gauge steady on cylindrical work while sighting down through a magnifying lens.
The contact edges are so short that the bit position looks correct in a small arc of adjustment.
For 32 tpi and above the level of error has to be low. So I ask because it bugs me.
