I made some test finger joints out of cedar and glued them last night. I ha nd-planed the joint today to see how it looked and it failed! The temps wen t to 45 last night. The glue is relatively new. I didn't clamp it but you h ad to wriggle in the piece because the joint was fairly tight. I've rarely worked with cedar. Is it resistant to yellow wood glue?

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 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 e projects.
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.

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 ke system 3 T-88 epoxy. No pressure required per-se.

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.
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.
