Burnt Shellac?

Hi, Lance.

Burnt shellac is just that, burnt shellac. You take regular, already
mixed shellac, and burn off the excess alcohol. It's a somewhat tricky
proceedure because alcohol burns with an almost clear, hard-to-see flame.
Since you probably wouldn't want to risk burning down your shop, it's
a job best done outdoors in a clear area, on a windless day. Fortunately,
there is a modern alternative that works quite well--PVC-E glue. Just
apply a small amount with a small artists brush to where the damper
wire enters the flange, or damperhead and let dry. Carpenter's glue
won't hold a wood to metal bond and will eventually let go; CA glue
will wick so deep that you most likely won't be able to unscrew the
wire from the flange again, without risking breaking something. PVC-E
glue is probably the way to go.
