What is the temperature in your shop? I don’t have a glue bottle handy to check, but I believe the working temperature for Titebond II is 55 degrees. My experience has been that if temperature was even close to that, had glue failure. The glue doesn’t cure at lower temperatures. Titebond III supposedly has a working temperature of 45.

Gripbd is spot on with the temperature assessment.

I had to bring in a glued up piece because it was wet after several hours in the shop. Once inside the TBII

cured but there was a pocket of glue that didn’t get the memo:

Anything below 60° is a no-no . . .

I agree with all on the temperature. Also make sure the glue is ready to use. even a new bottle could be a year old when bought. As stated on the bottle, shake it well before using to remix it from any separation in the mixture.

Wow! Low temperature is not something we think about here in Southern California. But, the temps here have been cold here for a few weeks, including frost warnings. Never thought about it effecting the glue. Thank you all.

How Do I Read The Lot Numbers?
Our current lot numbering system is a 10 digit code. The format is: aymmddbat#. The “a” stands for Made in the U.S.A. The “y” is the last digit of the year of manufacture. Digits “mm” represent the month, and “dd” represent the day of the month. The final four digits represent the batch number used for quality control purposes. Therefore, a product with the lot number A104270023 was manufactured on April 27, 2011.

I’m in So Cal also and it has been cold enough for my glue not to cure.
I do like the long open time :)

TB II needs 55 degrees F to cure, but of course it is time dependent as well.

It might cure in 2-4 hours at 75 degrees, but may take 24 hours in sub-50 degree temps.

I really like TBII. Don’t give up on it. Run some heaters in the shop or increase clamp time.

Some tropical woods are oily enough to cause adhesion problems (ebony for instance), but I’m not aware of any such issues with mahogany.

A problem ive encountered with glue bottles is customer purchase several bottles, takes them home & emptys 1/2 glue out into container & refil glue bottle with water, shake well then return for refund saying wrong glue.
next customer gets stuck with watered glue
I keep my glue bottle in an insulated box in winter so it cant chill or freeze.

i vote for tb111 ,which hasn’t much to do with the glue not setting .which is real odd . I am up in north bay area of calif . i do have a propane heater but it just to take the chill off . from what i have read tb111 has better adhesion with oily woods -though you were saying this is real mohagany which doesn’t strike me as oily . it has been my experience that tb111 sticks to more things .
I just put nosing on shelves ,pulled them and started trimming to fit and sanding after not much more then an hour . amazed yours did not set-up
