I've had some luck using the following method

1. sand panels to 220 if necessary

2. apply thincoat of glue to plywood and let dry(may need to prep
panel with dluted glue wash coat since ply can be v absorbent).

3. using a clothes iron on hottest setting and damp cloth, 'iron' on
the veneer starting from center out taking care to not burn veneer but
applying sufficient pressure to assure good bond

4. For best resluts grain of veneer should run crosswise to the top
ply of plywood and both sides need to be veneered

This essentially what you have with iron on veneer banding you buy.

As always - make sure to experiment on same veneer and size of panel
as fianl project.

I use regular titebond glue.

Have not tried this where veneer pieces need to be seamed together but
dont see why wouldn't work as long as you work the seam first.

Hi,

We were using white PVA glue during my veneering classes and it was
doing the job well. You gotta hurry up for large surfaces thought but
it's ok. As for the clamping, depending on the surface you have, you
may get away with a lot of deep F clamps. If you're lucky you may be
able to find those large presses made especially for veneering. The
problem is they're expensive if you have to buy them new (about 400$
each).

As for the veneering vaccum press, I know a company which makes an
more affordable kit but it still too expensive for casual use.

If you work on a large surface, your only choice will remain contact
glue.

If you want to know the in and out of veneering, do yourself a favor
and order the following book:
http://www.amazon.com/exec/obidos/tg/detail/-/0806928557/qid=1086662963/sr=1-1/ref=sr_1_1/104-2132505-9254322?v=glance&s=books

You'll learn all you need to know and much more.

Hope this helps and good luck,

Wally
