At Woodcraft today, I saw some Titebond Veneer glue. It’s a single-part glue so I’m assuming it needs air to “set”. The label basically just says it needs 45 minutes to 2 hours to set at 145-200 psi pressure.
I have a vacuum press and I’m wondering how well this would work. I’m thinking if it needs air to set, it may not work so well in a vacuum. Also wondering how much creep it has? Anybody tried it?

Good article about veneering in this month's FWW. Don't remember which glue the author uses however.

Measure it with a micrometer, mark it with chalk, cut it with an ax.

i have used it and have not had any problems. 2 hours in the vaccuum seems to work. not sure about the need for air to cure - since the vacuum also removes the moisture - which i think is what the air does - allows it to evaporate.

I used the Titebond Cold Press veneer glue with out a veneer press on this Baptismal Font. OPen time is good enough if youy need to fuss around.

I saw in a recent Titebond ad that all their glues have the same range of clamping pressure recommended for them (~145-200 psi).
Which made me wonder about veneering. It's impsossible to get over 15 psi with a vacuum press; 10 psi is more typical. And attaining 150 psi over any type of are area would be very difficult, by any measure.
I guess veneering works OK anyway with these glues due to the fact there is very little loading on the veneered pieces.
You can only get 1 psi for each 2" of hg or 2' of water that your pump can pull. I guess if you were to work under water at a depth of 260' you should be OK.
its probably PVA glue and is quite good in vacuum systems. Aloha, Mike
Maybe from the horse's mouth.....
