Cutting oil is my blood.
 
Beautiful stuff! What is the POP for? I am unclear on how/if you calibrate this device?

If it is like a normal Starrett 98, the vial is held in the brass tube with plaster-of-paris. When you restore one, you use water to 'melt' the Plaster, then have to re-apply it after.

The POP is used to hold the vial in the tube securely. As it is just a slip fit right now. That is how Starrett levels are done. So if it is good for them it is good for me.

As for calibration it will be done on my surface plate. Per the attached video.

Keith has a great video on both of these questions. Well worth the 30 minutes.

I was too slow responding

Did you use a ball end for the entire cut?
Looks great

Yes I did. I setup in a vise and did the first cut. It was on center and to depth. I then setup on the 45 and side milled the angles to finish. Being careful to keep centered.

I did an inspection of the groove and it is within.0004 parallel to sides and about .0002 to base.
