I'm a cabinetmaker and joiner and deal with veneers almost everyday.
I can say that from my experience it's not worth the hassle in glueing the veneer on yourself when there are companies that will do this for you on whatever substrate you'd like with a proper press.
Every time I have contacted veneer on it sticks very well but as soon as I put a polyurethane clear sealer coat or topcoat on it the thinners in the paint lifts the veneer off due to eating away the contact. This gives you a bubble effect and it is not redeemable after this has happened.
If I have to do it now I use a vacuum press and either pva for small pieces or a 2 pac epoxy for large area stuff or whole sheets.
As I said above it will be better and more worth while in the long run to get it layed up by a board manufacturer in the thicknesses you need.
That's what we do and that's my opinion.
Hope this info helps your decision on how to go about it.
Cheers
Dirk.

almost certainly -- it will allow you a much extended working time
but you may wish to readup on how hammer veneering is done with hide glueregards from Alberta, Canada

Bugger. I appreciate your expert advice - I'm a fair way down the road in this project - perhaps will try a water based varnish (but that will probably swell the veneer??) or maybe another type of topcoat (open to all advice!). The vacuum option is not really available - not ready to invest any more in this equipment at the moment. Will do some small test pieces and keep my fingers crossed!
As said, I really appreciate this expert advice!

Waterbased poly will be fine to use.
I was just reading what I wrote last night in my tired state and I think it came across that you CAN'T contact and poly it at all.
This is not true and sorry if I lead you to thinking this. As I do a lot of veneer work and we always need it asap the contact is a no go for us. If you were to contact it and leave it to dry for a decent amount of time say about a week in the cold weather it will work but when you go to poly it you'd need to spray a really light coat of sealer or topcoat first to seal the veneer so that when you lay on the other coats it won't penetrate through to the contact.
Hope this is more clear.
