#I think a turpentine cut SHOULD be a cut made in a [pine, etc.] tree for
#collection of turpentine. I speculate that the above sense is metaphoric,
#referring to a ragged slot or so. I can't find an example of this usage
#immediately.

I am no carpenter, even as an amateur, so the following may not be
reasonable. I thought on reading Gerald's question that perhaps a sloppy
joining would, under some circumstances, "bleed" resin from what should
be a tight junction.
