He, he,
Yup, going to, and did. Job is done, and I first refinished the rails in
shellac, then sized the holes with alcohol/water. Really, it is too easy
(thanks, Ron).
I must admit, I didn't actually give any of the bushings a tug afterwards.
I figure that the adhesion is really only necessary to prevent errant
replacement of a single damper (done it) or some such in the future.
However, since the process was so simple (it is) why not have a little
(easily undone) adhesion to keep the bushings in to prevent headaches at an
inconvenient time.
Maybe I'll give 'em a check when I in the shop again (a couple days).
