agraffe stub misery

[David Nereson]

Will a drill bit extender work?  One kind is essentially a sleeve with set screws.  The other is a shank with a one-ended sleeve (cylinder) with set screw(s).

  Sure, sometimes it's EZ, but other times it's hell. The customer has a big (7 ft or so) old (ca. 1889) H F Miller grand, and there's a popped off agraffe at the note just above the top treble section strut. A couple weeks ago I was at the customer's home, at which time I tuned & voiced their Yamaha G3. After finishing that, I took a look at this big ol' relic. I tried the "tap a snaggle toothed screwdriver into the stub remnant & back it out" routine. Also the "see if you can tap it counterclickwise to back it out" scenario. No go.
  Well, I knew my left hand bits were back at home, so I packed it in for the day. Made a follow-up appointment for earlier this morning. Set my high torque drill and left hand bits down, opened the piano up & took another look at that agraffe stub. OOK, it's RIGHT NEXT TO a massive (3" or so tall) strut! The chuck on my drill is way too fat to center the bit into the stub. So my plans to drill a hole into the stub & spin it out were thwarted.
  So what's my best option? I don't think I'm going to find a set of superlong left handed bits. A very skinny flex shaft? Anyone have a preferred brand? A while back my local hardware had a very lame looking (no name China made) version -- I would prefer to get something others have had success with.
  Thanks in advance,
