Agreed that most boring heads have these screws but the gib is normally part of the head and is rigid, in this case the gib is loose and held in place by the threads of the SHCS and the pressure of the set screw. I would think that under pressure this gib would have tendency to lift and cause chatter.
Now if you had two other screws holding the gib down to the head after adjustment that would surely help. I presume you will have the boring tool pointed towards the adjustment dial, that way the cutting pressure will be against the solid dovetail side.
Anxious to the next steps, specially when mounted to work on the radial.
