I do a lot of veneering and hide glue is all I use. (Yes Bill, I'm old )
There are many reasons for using it over "modern" glues but reversibility and lack of creep are high on the list along with the ability to use the "hammer" veneering technique.
Really almost any glue will work but only hide glues and urea formaldehydes will dry hard. IMHO that is important for veneering.
I have read that hide glue is the old tried and true glue.
At this point, I want to try something easy for small panels. I do not have a vacuum press and will use clamps. I have watched videos and read and it seems like a lot of different glues have been used with reasonable results. I have seen even yellow woodworking glues used and also Titebond 2. These glues may not be as God as hide glue but w h at do you think about them?
If you don't want to use hide glue, titebond makes a cold press glue. Be advised that you want to put as many clamps on it as you can with thick cauls to evenly distribute the force. Clamp the center of the panel first and work your way out. Otherwise the glue will make the veneer bubble.
If you use hot hide glue you can veneer without a press or any clamps. Hammer veneering uses atmospheric pressure just like a vacuum bag does but without the equipment. You can also veneer after assembly of the piece of furniture.
Check out this blog. You don't need to buy a real vener hammer right away. Many make shift "hammers" will work fine like this one for instance.
That particular segment is about hammer veneering but the series is an intro to hide glue in general.
Tightbond hide glue is real hide glue but it is liquid hide glue, not the same as the hot version. You need hot hide glue to hammer veneer.
The glue has to be on both sides to insure no dry spots and make the whole process work. As the HHG begins to cool and gel, the edges seal and then as you work the air out, no more can get in and the veneer is "vacuum sealed" down.
Speaking of Titebond, I find it interesting when reviewing their specs. Lots of guys seem to use TB all the time for their vacuum bag veneer work. (Others avoid it) But the TB specs recommend pressures ranging from 100 psi to 175 psi. A vacuum press applies (in the range of) 10-12 psi. I've used TB (Original, TB II and TB III) in vacuum veneering with no problems. (no commercial veneer, all shop made/extra thick) - but if you just go by their specs it would seem logical to assume it's not the glue to use. Puzzling huh?
