Oh, one other quick note... The angle measuring strip on the round part of the swivel adjustment is not to be used as a reference point for determining angles. As is the case for any markings of this type (be it a lathe compound or mill swivel) it's only there as a rough guideline for angle positioning. This applies to both engraved and surface label markings.
If you need to set a "good enough" angle, use a sine plate or other precision tool and adjust the tooling to match the angle.
If you need "dead on" angles, use two travel indicators (or DRO as the case may be) in the X, Y or Z direction and calculate angles by taking "Rise over Run" type measurements, combined with the appropriate math (Sine, Cosine, Tangent) to verify dead-on precision.
The engravings or labels are the last thing in the world you use to set an angle.
