Hello,

I've been told that running glue-ups through a planer or jointer is not
a good idea. The dried glue apparently has a damaging effect on the
knives. Any other ideas/opinions?

Certainly large amounts of dried glue are going to do a number on the
knives, particularly non-carbide...that's what (a) avoiding excessive
squeeze out initially, and (b) glue scrapers are for...

If you are talking about edge glued panels, that isn't the only reason
not to do it. Unless the grain is going in all the same direction,
which is very unlikely, tear out is all but guaranteed. Once the panel
is glued up, go to hand planes, scrapers and sanding. I use a ROS if
sanding is called for. Your glue-up should be close to flat and level
after it dries. If it isn't, then something else went wrong.

Some are much worse than others. PVA, the common "carpenters'" glue is
fairly benign. Resorcinol and other tough ones can chip edges.

Back when I had access to a planer large enough for a glued up panel, I ran
quite a few of them. Never had a problem with tear out. Did oak and walnut
and cherry, IIRC.

And after you scrap, sand off what you can of what remains. Your blades
will thank you for it.

My blades don't talk to me -- trees on the other hand... :-)

Depends on the glue. Most of the everyday glues you'd apply yourself are
OK, most of them used for commercial plywood are a bad idea. You can
cerrtainly do this, and you won't destroy anything instantly, but expect
accelerated wear on the knives.

Same thing applies to hand planes.
