As another poster here suggested, dye the surface (that will be glued
later in making up your woodblock) and when the project is turned, a
very thin colored line will show up. The glued (and dyed) surface is
wood-to-wood, and so will be as strong as any other glued part of your
project.

Actually, I'd question the "as strong" part. The adsorption of the dye
reduces the adsorption of the glue. Maybe a very minor amount, maybe
more.

If any reader has done some sort of testing on this, or knows of some
tests, I'm sure we'd all be interested in the results. I mean testing
with measuring equipment, not just "it worked (or didn't) for me."
