Inner flap string guide 3

2nd attempt (what we ended up using).
It replicates both the screw and bushing for the inner flap hinge pivots.
Worked well, used JB KWIK Weld to hold in position along with a green tipped clamp.
I made the .0145" diameter hole starting with a mini center drill, then using a light pressure drill-feed attachment holding the small drill, and the larger chuck in the lathe tail-stock holding the light pressure drill-feed attachment:

Light finger pressure applied to the aluminium ring allows for about 1" of travel. The ring has a ball bearing, thus if you were spinning the small drill bit in a milling machine or drill press, finger pressure can be applied without the ring spinning between your fingers.
