For a recent project I had to glue up walnut legs. In my very small
shop the table saw usually ends up the surface of choice for doing
this. I layout a sheet of wax paper to protect the top from the glue
up and minimize the amount of my barrier sticking to my project because
of squeeze out. This has worked very well up until the walnut. I
glued the parts using tite bond III, had a normal amount of squeeze out
and left to dry over night.

In several areas where the squeeze out had set between the walnut and
wax paper it had leeched or eaten through the paper. The glue had
absorbed some of the wax and turned a dark purple/black with the
consistency of melted crayon. Some steel wool cleaned up the table saw
and a quick 1/32" pass through removed any trace of the stained glue
on the surface of the wood. So all ended well but, any ideas what
would have caused this?

go to a fabric store and buy a nice sheet of thick waterproof
upolstery. That's what I use to cover my bench when doing glue ups and
finishing. Get a piece big enough to cover your surface. Fold up when
done. Lasts forever (even though it gets kind of ugly).
In the long run, it saves you from buying all that wax paper.

Is there any chance that there was a residue of somethign like
WD-40 or mineral spritis on the tablesaw top?

If not, the culprit would seem to be the walnut itself. Could you try
glueing some scraps to see if the effect is reproducible on a different
surface?

Have you ralked to TiteBond tech service yet?

I haven't contacted titebond but that's a good idea. The only thing on
the top is a coat of Johnsons paste wax. I've been using that for
years coating it about every six months or so with very good results.
It was about 3 months since the last coat.

Thanks for the ideas. I may indeed beef up the gluing barrier to
something more substantial.
