Ok, I haven't a whole lot of experience, but I have had this happen with PVA. It happened when I had insufficient glue (actually, I think it was also too old, that bottle gave a lot of trouble), causing adherence problems. Since I was using PVA, it swelled the glue some an wherever it didn't adhere I got bubbles. In some areas, that made for a wrinkly appearance. Better spreading and more glue solved it. It could also be your pressing technique (what are you using to press? How much force?) or any other number of things that could cause grief.

I do expect a non watery glue like Unibond could certainly help since at least the veneer wouldn't swell so much.

Hat,

Birdseye maple is the single most prone veneer to wrinkling, so its not all you.

A couple of things, make sure you are not putting any glue on the veneer itself, only on the substrate, and if you are using a vacuum press make sure there is a caul between the veneer and the bag, do not press directly against the bag. If cold press glue is what you want to use then the key is to work as fast as possible. Have everything ready so as soon as the veneer touches the glue you are in the bag and the vacuum on as fast as possible.

There has been a lot of discussion around this board lately about glues.

Some people hate PVA's (me), and some people love them.

My two cents - start with Unibond 800, or another urea resin as your primary glue, then experiment with others.

Or in the interest of some of the varied opinions....it sounds like your problem is probably adhesive related. Try different glues overall, and see what works best for you.

But since you are getting lots of wrinkling, I would be willing to bet that you will get better results with a glue that doesn't contain water.

Thanks I'm new to veneering. I have started out with a homemade press. from Joe the woodworker. It works great. So my next purchase will be the unibond 800. I thought it might be the glue. All the wrinkles seemed like it was moist. Like I said I'm just starting out. I'm a decent woodworker, but when it comes to veneer I'm learning. Thanks for all the great feed back. Hat

Hat,

As an experienced woodworker just starting in veneering, I think you will gain a lot of information very quickly by watching Darryl's two videos. One section covers the various glues and when to use them. I found both videos to be extremely helpful.

Having not found a book I thought was well written on vacuum veneering and veneering techniques, I am quick to recommend videos, especially when they are clear and complete. I would definitely second the recommendation to purchase the two by Darryl Keil; I would also strongly suggest the two by Paul Schurch. There is some overlap between the two authors but there is more than enough unique material to the two authors that they all are well worth having.

Are you trying to glue two panels at once back to back? I've gotten wrinkles with Tightbond cold press when trying to do two panels at once. Now I only do one at a time and don't have any problems. But make sure you work very quickly once you put the veneer onto the glued panel.

I also use a JoeWoodworker home built system. Make sure you don't have any leaks and are pulling at least 20" HG pretty quickly.

No leaks in the system. I"m glueing to plywood. And one panel at a time, Just making some drawer fronts. And I will buy the dvd's. Also how about using plastic resin glue? I have seen David Marks use it. Thanks Hat

Someone correct me if I'm wrong, but I think generically "plastic resin" glue is one part powdered urea formaldehyde glue. Pro-Glue is available in both two part and one part versions. DAP Weldwood Plastic Resin is a one-part (powder) urea formaldehyde glue. Unibond is only available as a two-part glue.
