When I repadded a Leblanc paperclip two years ago I shellaced
the pads in and then put the resonator on the spud. It seemed to
work pretty well. I had no trouble floating the pads even with
just a little shellac.
I told you all a few months ago about a Selmer plastic
contra-alto that had broken. We sent the lower joint to Selmer,
and they simply replaced the joint. Five days ago I did the key
transfer and was lucky enough not to have to replace any pads.
VERY LUCKY!!! I floated most of them, tweaked a few of the keys
so the lod seats would match up with the new toneholes. When I
got done I, of course, had to play test it, and I was absolutely
amazed at how easy it was to play. WOW!!! I moved up and down
both registers and back and forth between them more easily than
I can on most sopranos. WOW!!! I gotta get me one of these
things one of these days!
