I know that none of you make mistakes but I have made one and I would like
suggestions about how I might correct it. I have face glued a 3" by 22"
piece of plywood to a fairly wide piece of birch plywood. At this point in
the project, I can not easily disassemble my project so I am faced with
trying to somehow pry off the 3"x 22" piece. If I can do it I am quite sure
this will mess up the faces of both pieces of plywood but this is internal
to my project so there are no points for looks but lots of points for
functionality. Any clever ideas for me?

That's the £300 SuperCut. The Multimaster is £150, which starts to
look affordable for some jobs. I'd love to know just how much
difference there is between these.

The glue is Elmer's Carpenter's Glue (yellow interior glue). Unfortunately I
only have 5" to work in so I can't get a router in there. :-(

Mix some vinegar with water, warm a bit and drip the mix along the glue line.
Give it time to soak in, pry a little, drip some more, etc. Plain yellow glue
should let it come off that way.

But it would have saved $12 worth of plywood! ;-)
Glue is degraded by heat. Try using a hot air gun on a lowish setting or
perhaps a steam wallpaper stripper and work slowly along the strip, gently
levering with a sharp paint scraper or somesuch as you go.

may give you food for thought.
Cleaning up the glue afterwards could be a problem.

I don't think you're going to pry it off.
Can you destroy the glue (what sort is it ?) without hurting the
timber? Otherwise I'd try to machine _through_ the excess part
(probably with a router on skates) and work down to the original
surface.
You can't often dismantle things. So it's best to accept you're going
to break _something_, pick which one to lose and then really trash it,
without hurting the other.

set up a router with a straight bit at the depth of the thickness of
the 3x22. make cuts that leave behind just enough to ride the router
on, more or less a checkerboard pattern. bust off the remainder with a
chisel and clean up with a belt sander.

Well you screwed up there ! - That was the perfect excuse to buy
yourself a Fein Multimaster. Shiny new toy, fits into your 5" space

Thanks for the help from all of you. I got it off with a heat gun and a LOT
of chisel work. No room to use any power tools in that space.
