Well... you really shouldn't run a glue up through a planer. The
glue will play hell with your blades. No glue, no poaint, just wood
ro the blades die. Also, if you have any spring or cup in your glue
up theplaner might crack the glue joint.

Get a drum sander or wide belt sander if you want to flatten glue ups.

Disagree on both counts. As long as it is huge globs of a very hard
glue, the glue isn't as hard as most woods and won't do any significant
damage to a planer (or jointer) knife.

And, as has been demonstrated in many tests, a good glueline joint is
stronger than the surrounding wood; if there's that severe a cup and
there's a failure, odds are very high it will be the wood that fails,
not the glueline.

Not that having a wide belt sander isn't a good thing but certainly it's
not a verboten to plane down a glue up.
