How to unglue something without wrecking the wood
 

This post is sort of related to the one about carpenters glue solvent. I
made a mistake gluing two pieces of cherry with yellow glue. My first
instinct is to use water to soften the glue but I wonder if I will wreck the
wood doing that.

What is your advice?

TIA.

I should have mentioned that a 3/4" piece of cherry is glued to a second
piece of cherry so I have to loosen the glue in a 3/4" by 26" joint.

If possible, for instance if this is a panel glue-up, just rip along the glue
line and compensate for the loss of kerf thickness somewhere. In my own
experience, trying to separate 2 pieces glued with yellow glue is a crap
shoot. Whether you try softening the glue with water or some other solvent,
there is still a good possibility that wood on either side will crack
before the glueline separates. If you can just rip or saw the glueline,
you will be in controll of what happens, with other methods there's
no way to be certain what will happen.

I don't think it would ruin the wood.
You'd probably have to let it air dry for quite a while.
If you can submerge it steam, that may work.

I have a piece of cherry 26" long edge glued at a 90 degree angle (actually
it is 85 degrees which is the problem!). I can't really rip the joint
without ruining both pieces of wood. I will glue up a test sample and try a
heat gun per Lew's suggestion to see what happens to the cherry.

I vote for the heat gun, also. Just don't burn your wood, which can
eassilly happen if you don't watch carefully.

I'll Jump in with Larry on this. If you have extra width to work
with, rip through the glue joint and re-do it. I recently restored
an antique elm claw -foot table that had several cracks in the glue
joints (likely animal glue) in the top. After some careful measuring
and head scratching I ended up ripping through the joints and re-glued
them. In this case, I had to compensate for width with the edge trim
but it worked quite well. If width is an issue, you might be able to
use a thin-kerf blade.

Which brand/formulation? Titebond I will loosen with heat. And vinegar
will loosen it as well.

But not Titebond II.

Not sure about other kinds of PVA glue. If they are general purpose,
heat or vinegar should do the trick.

All the Titebond glues are PVA types, and PVA softens at about
boiling-water heat (or maybe less). I've used hot water with
vinegar and it worked, but maybe it was mainly the heat.

You have to be very careful and not let the knife get too hot or it can
burn the wood.

Again, PATIENCE is a virtue.

Totally agree.

The glue needs to get hot all over and all through all at the same time.
That takes (here it comes again) PATIENCE ! ! !

A low heat applied for a long time.

That depends upon the glue. In some/many cases you don't...you cut them
apart and glue back together later. But why do you have to take it apart
to refinish??

Well,
Since it is just two boards, if your kitchen oven is wide enough, you could set it at 210º-215º F and leave there until the glue softens.

How about a Steamer Box?

Yep, I know the thread is older than my cat. Just looked interesting.

It would probably work if the piece would fit. Most steamer boxes I have seen are long and narrow. My other concern would be whether the steam would warp the piece.

That would likely depend on the glue used.

Steam for Hide glue.


Vinegar for modern water based glues.

Whatever works best for the particular situation.

I've been working on a related case for the past 2 weeks.
Background: 2016 flood affected a slat-back oak chair dining set. Dr. owner had a patient do the repairs, refinishing. The patient, I think, didn't know what all to do, what to do properly and/or should be done. Seems the chair seats had warped and started coming apart... several boards per seat.. Chair frames had come apart to some extent, also. Since flood damaged, don't have to worry about messing up a finish.... heat gun use.

The guy tried to glue the boards back together without cleaning the edges or jointing them square, to mate properly. Lots of mold and mildew still on the board's edges. He ended up with gaps between the boards, then tried a white-ish filler to fill the gaps (on brown boards). *Subsequent stain on the chairs is Old Masters Provincial stain.

Beyond that, he seemed to not clean the stretchers for re-gluing into the legs. He shot wire nails in some, for further securing. He shot wire nails in some of the backrest slats, as well. I haven't/won't attempt to remove these nails.

I separated the seat boards using a heat gun. I worked the heat along the whole length and the boards slowly separated. Took about a hour each seat. On all 4 seats there were some glue lines that I sawed through, rather than using the heat gun. I flattened any major warping, then jointed the edges clean and square before gluing. Also added a strip of white oak to make up for removed seat width, from jointing and sawing.

Yesterday evening I put the first coat of finish on. 9 pics, scroll right.
