Hello.
Iīm trying to improve my skills and bought H.Hallīs book:Lathework-a complete course.
For my first project,Iīm building the little surface gauge.
Now that it comes to the cut that has to be sawn in the base as a part of the adjustment fixture,Iīm wondering if itīs meant to be circular or just at one side.The drawing and the text is not that clear to me.
Did anyone build that gauge too and can give me a clue?
Iīve found to pictures of a finished gauge:

The V-groove, that is meant to camouflage the unsightly handsawn cut,is going all around;but I canīt see the sawn cut in itself.
Anyway,here are some pictures of my current progress:

The base is turned already.Trying to level the base for flycutting the flat and drilling the holes.


Holes drilled,than deburred.

Turning the necessary thin piece collet.
