Acetone simply cleans the surface, I think you should look at the working
temp range on the bottle.

Thanks, Lew. I tried Gorilla glue for the heck of it. But I'll also experiment with acetone and epoxy.

Temp is one issue. Cedar should be fine with yellow glue as long as it is k=
iln or air dried to lumber status. However, yellow glue depends on pressure=
as part of the curing process. Otherwise there is no assurance you get muc=
h bond. Sounds like no pressure in this situation. I would use something li=

I have glued the cedar picket on occasion with good results. I have had
glue failures with oak face to plywood in temps not quite as cool as what
you were working in.

Will acetone help yellow glue set, or is yellow glue just not an option?

Epoxy doesn't like 45F.
Try to maintain at least 65F until the epoxy kicks.
BTW, you also want to clean with acetone first.

Given proper surface prep, properly fitted joints, adequate clamping,
and temps above 60F, about the only real advantage of epoxy over
yellow glue is open pot time.
Yellow glue has about 10 minutes at best while laminating epoxy with
slow hardener has at least 25 min at 77F.
Glad to see you learned your lesson about Gorilla glue.
IMHO, it is garbage.
Have fun.

I have been gluing western red cedar for years with yellow glue and urethane
glue. Never had a problem. But keep it warm for the first 24 hours.

I've not had problems gluing eastern red cedar (juniper)... I cut the trees
down, sawed them, dried the boards for 1-8 years before use, and glued them
with yellow glue.
A question/thought.
Was the dry joint tight enough that it could have essentially wiped the glue
off as the pieces were pressed together during assembly?
I'm thinking that if the dry fit was tight and the wood very dry that
perhaps you needed to apply glue to all glue surfaces of both boards so that
glue was in fact in the joint when it was pressed together. By coating all
surfaces of both boards the glue would have time to soak in to both boards a
bit prior to assembly and not leave you with a glue starved joint.

Thanks. I'm going to make another joint, bring it in the house, and clamp u=
p a little bit. I do not enjoy working with gorilla glue.

Acetone will cleanup the oils so that you get a good bond.
Yellow will work , just wipe with aceton, let it air dry 1 minute or 2
then glue.. either yellow or epoxy. Like Lew said low temps are
generally not good for any glue..

I think this might be a case of really dry cedar. I got several wide boards=
free from someone who was cleaning out his shed and wanted to get rid of t=
hem. They had obviously been there a while. I thought I would make a few bo=
xes out of them, but the gluing issue might make this a series of cumbersom=

Hi John,
That's a great point. I'm going to try acetone, warmer temps, and more and better spread glue. Appreciate the input from everyone.

I just un-clamped some cedar boards that I edged glued into panels for
shelves.
They were very dry boards on which I ripped fresh edges and joined,
three-wide, with regular yellow Elmers carpenter glue, tightly clamped
with good parallel clamps.
First inspection: everything is normal, glue is dried and boards are
staying together, tightly.
I'll report back if anything changes.

FWIW, I took some cut-off sections of the joined shelf boards I made and
bent then until they broke. They broke in the middle of the board and
not at the glue joint, as I've experienced with every other species with
which I've done this same experiment.

Fresh unweathered cedar is "resistant" to most glues. Polyurethanes
like "gorilla glue" work inmany cases - and wiping down with acetone
before gluing can help as it removes the natural oil from the
surface/fibers. The right moisture content (less than about 15%, but
not too dry (like less than 5%) will let normal wood glues cure
properly

I bought a flat bed load of western (mill pond) cedar back in the late
70's and I still have some. I've used both epoxy and titebond and
never had problems. It was all rough lumber so was always jointed and
planed prior to gluing. Never used acetone and always had good luck
cedar will definitely break before the glue joint. More then likely
the low temperature is at fault.
