It would help if we could see a picture of the key, but I suspect John =
Ross has the right approach. And John Delmore is correct to suggest =
concern for the repair strength. Chances are that you will not have =
perfectly mated repair surfaces - which are required for most glues. =
This is a perfect application for the West System epoxy two-step bonding =
method, and IMHO, will result in the best, strongest, most accurate =
repair.

> For added strength (you don't want to have it break again!), you could =
consider sawing as you mention, then making two evenly spaced =
longitudinal cuts across both sawn surfaces, and gluing in splines with =
the grain traversing the oringinal cut.  If you're very careful about =
lining everything up perfectly, it should come out okay, maybe a little =
trimming/sanding.  I think carpenter's (yellow) glue would probably be =
appropriate, since, hopefully, no-one will have to re-visit this one!

  I think that when the key was reassembled to glue, it wasn't lined up =
properly. So that, made the key, pulley.
  The veneer on the sides would have been added after it had been glued =
back together.
  Fix is remove veneer, break and reglue to the proper length, and =
reinforce the sides.
  Having said that, I don't know if it can be done, getting it back =
right. Too bad the original repairer, hadn't been more careful.

    Got a call from a lady who said, 'her key was broken'.   Skeptical, =
I asked her about it, and she says that two technicians have tried to =
fix this key and now it's worse than ever.  So, intrigued, I made an =
appointment to go look at it.
