Working with Veneer - A Step by Step Guide, from Start to Finish
Working with Veneer was originally released in 1995 and while the video quality is dated, the information remains as true now as it did almost 30 years ago. This video focuses on the basic skills of veneering and goes through the entire veneering process, step by step - from raw veneer to a completed 4-way matched walnut burl table top. Topics covered include: appropriate tools and jigs, flattening buckled veneer, matching and sequencing veneer, and studying different types of glues - as well as jointing, taping, and gluing techniques. Every subject is carefully examined and demonstrated. If you’ve wanted to try your hand at veneering, but lack the technical knowledge to work it, this video will give you the confidence to try this exciting medium.

Vacuum Pressing - Outside Technique

In this video, Darryl demonstrates the "outside technique". With this method, only the laminations are placed inside the bag. The form stays outside. This technique is commonly used when the form is too large to go inside the bag without difficulty. Instead, the craftsman brings the laminations to the shape of the form. The VacuPress clamps all the laminations to each other, eliminating all but...

What would be a proper glue for veneering without a vacuum press? Because UnivondOne is not available in Mexico.
Extremely useful and great explanation. Thank you sir.
Weldwood Plastic Resin Glue is no longer available. I found a similar glue but only available in 10lb buckets or more. As the presenter says it’s not a good idea to keep this powdered glue around for too long. Any advice on where to buy smaller amounts would be appreciated.
We are unsure where to buy small quantities of the powdered resin glue.
My woodworkers got glue stained on the veneer where it joined two lge pieces on bench. After staining it showed up big time. Probs is veneer is very thin. Any ideas how to get it to dissappear?
At almost an hour and a half, I was thinking "Oh lord." A lot of good information well presented. This video flowed in a logical order taking the time you need to explain, but never wasting any time. The video production was as impressive as the information and the instructor was. This is time well spent with the last couple of minutes might be the best. Thanks!
Outstanding presentation. Thank you.
Fantastic video.
Thanks,very informative.
Thanks for that softening recipe! Wow, gold.
I like this guy!
I wasn’t ready for such an exhaustive explanation. Very clear, either the dos and don’t. I’d recommend playing at x1.25 speed if you can follow, as the speaker speaks clearly and slowly.
What a great vid with all the tests. I love wood, and my favorite, living on a boat is PU glue (in Europe we have the Dutch company Bison as top glue brand). Thinking about to build a wooden rowing boat (single skulling Skiff) with glueing 4x veneers to get a 3 mm thickness hull wall via Diagonal strip planking method. Still have to think about if I take paper backed veneer to have some more stability during the curving over a hull form. Racing rowing boats have extreme curved hulls. - Tks for uploading the vid. Appreciate your efforts a lot.
Great video! Thank you!
What gauge was the vinyl and poly you used?
The demo pieces are 15mil, our bags are 30mil.
Can resin glue be used to bond veneer to hardwood? I know pva can't
Urea resin and PVA glues can be used to bond veneer to hardwood.
@@VacuumPressingSystemsInc do you mean your specific pva glue? I've always heard that pva should only be used to bond veneer to PLYWOOD never hardwood
@@abeannis I am not sure where you received that information, but PVA glues in general can be used for veneering to hardwood. There are reasons why you might want to avoid PVA glues for veneering, regardless of the substrate, but that is a much larger topic.
You should make the distinction between interior and exterior applications. For exterior you definitely want a flexible glue so it can contract and expand with temperature.
Logically you would think that to be the case, but most exterior glues are quite rigid, like epoxy and resorcinol. Exterior glues are thermosetting, mix part A with part B, making them very hard. Interior glues, in general, are the softer ones, which is why you get “cold creep” with interior glues, but not exterior ones.
Such a great video this shout be on page one of every veneering Manuel
I am sort of wondering why a platen is un needed on the top. I’m not doubting this but am guessing that the principle of the grooves and or the netting must be on the underside of the project (over the nipple) as that’s where the bag could seal against the project without all the air escaping entirely? So if the platen is on the same side as the nipple, then the air escape issue is resolved, correct? Thx much.
Yes, that is correct.
I’ve read the most common vacuum is around 21” mercury but my pump (and I assume most) can go higher. Would you recommend setting it to a higher number for most projects? Thank you for another really exceptional teaching session. Best.
A vacuum pump designed for pressing and laminating generally pulls around 25-27inHg at sea level. 21inHg is plenty of pressure for most work. We set our vacuum pumps to maintain a range of about 20-26inHg.
@@VacuumPressingSystemsInc thanks so much 👍
Quite a few high end furniture makers I’m aware of do use pva glue in veneering but maybe it’s better for some situations than others. But definitely used and quite successfully. That being said the info here is very helpful and important esp if a piece has a risk of heat or moisture. Thanks for the great channel. Just getting started in the world of veneering.
PVA glues definitely have their uses in the world of veneering. It's all about knowing what glue to use for the application.
happy to see new videos coming out!
Big help more information than the previous ten videos I watched. Thanks
Thank you for putting these videos out, they are a wealth of information. Great Video.
You're welcome! We are happy to hear that they are appreciated.
Do you ever offer discounts to your products? I’m in Canada and find your system fascinating.
Thank you for the question. We do not run sales or offer discounts.
@@VacuumPressingSystemsInc Thanks and no problem. Do you have any distributors in Canada?
@@measuretwicewoodworks We can ship directly to Canada and our Canadian distributor is Veneer Systems, Inc
Thank you for showing the “outside” technique! That explains how large curves can be obtained! Also, the tip on the”light vacuum “ to get everything dialed in will aid in a good result the first time. Thank you for the continuing education!
You're welcome. Glad you enjoyed it.
Thank you for the detailed info in the video! I have a question: I experimented with some oak veneer, with no vacuum press, and I found out that PVA glue tends to work very well but after a couple of days, the veneer develops some dark spots of blueish black colour. Should I use a bleed - through blocker? If yes, does a thin shellac coat work as a blocker?
apparently they no longer make the Weldwood plastic resin powder.
Very well presented and useful information. It was exactly what I needed. I'm flattening some complex grain warped pieces which can't be replaced. I need the really stiff urea-urethane versuion.
Excluding surfaces expected to get wet, hot hide glue is still your best all around veneer glue. No vacuum press, no clamps, just a veneer hammer (a simple squeegee) If you screw-up, just wet it, remove it and try again. Be sure to buy the heater element and the granulated glue.
Without a doubt hide glue is a great veneer glue. It's been used for a long time before modern glues became popular. The fact that it is reversible has its benefits, especially in antique restoration work. There are a few reasons why it has fallen out of favor and why I only gave it a mention in the video. First, it's a fussy glue to work with and takes an extra skill level to master well. Second, you don't have the open work time that you do with other glues, making it somewhat limited. Better for smaller panels, and like I said, great for antique restoration work.
@VacuumPressingSystemsInc I've seen veneers applied to curved, vertical surfaces while standing on a ladder using hot hide glue. The little heater element was perched on the ladder paint platform. It was about as complicated as hanging wallpaper. I don't know any other glue that would have worked. Veneers that were misaligned were simply wetted down, pealed off, and reapplied. Today, hot hide glue is notoriously overlooked.
Is it possible to veneer a guitar with the neck still attached (set neck)?
Yes, though it is not something we have experience with.
as a refinisher, i gladly like the adhesives that are softer and thusly easier to reflatten veneer. the adhesives you suggest are a one and done with little to get under and repair the substrate. what are the solutions to resoften you adhesives to reglue your buckles . if you are applying those hard glues to core the backer then veneer, then there is a bubble , how do you settle it. im asking to finishers about where their art will be in 30 or 50 years who fixes it or can it be recovered. thanks again great info.
We recommend a hypodermic needle and super glue for fixing a bubble.
Your video is very helpful, thanks. Ray from Germany
D'oh! I just vereer'd some panels with TB III (longer open time). I wish I knew about Urea glue. Oh wait @13:40 Whew! I was using a woodbacked veneer so I guess I'm in the clear. Great information.
👍👍👍
What a lesson!
Hello sir. Kindly guide me how to use urea formaldehyde resin in chipboard making and material formulation.thanks.
We are not in the business of chipboard making. You will have to look for answers elsewhere.
Great, great knowledgeable video, thanks for every bit of info… but the wall behind you is frankly depressing. Could you pour in colors, shapes and personal memorabilia?
Depressing...I'm crushed!! What about the red in the clamp handles and the orange handle of the scraper. Thats some color?!
@@VacuumPressingSystemsInc Man! So sorry, I didn’t mean to come up that rude! It’s just that I’m 43; so basically I’m way more into content than aesthetics, but I was also raised by the likes of French MTV, cartoons and gaming systems, so my expectations are at medium, medium-rare, when it comes up to a YT decor. In other words, I don’t think that your set reflects the extent of your knowledge. In my opinion, anyone below 30 will pass on your vids within seconds, and that’s a shame. So, sorry for not giving you the key to my comment. And thanks again for a convincing exposé.
@@Jeedehem I appreciate the honest feedback and will take it into consideration. No promises though, likely more "depressing" walls for at least the next couple of videos.
You talked about the value of a long open-work time, but then you said you designed your urea glue to set faster. Somewhat confusing. Without any mention of actual working times, it's hard to compare.
I've seen lots of minor veneer repairs with super glue. Seeps well into tight spots; can be injected with tiny applicators.
Yes, super glue in a needle is a great spot repair solution.
Minimum temperature only while curing? While stored? After cured? Need clearer explanation.
Only while curing is the temperature important. Storing temp doesn't matter but the shelf life will be better if the liquid part is kept cold, like refrigerated.
Very inspiring. Thank you sir
Isn't phenol resin used here instead of urea formaldehyde ? I think UF has transparent color
Unibond 800 is a urea formaldehyde resin. Phenolic resins are generally used with plastics.
where can i buy unibond 1 in Australia? thanks
There are no suppliers of Unibond One outside of North America.
That is very informative, and I am ordering some Unibond 800 from your website today. I have two questions: 1. when to use the bleed blocker, I am using a lot of walnut burl and olive/ash burl - would I need a blocker for these? 2. do you put little bit of Unibond 800 into the seems before putting the veneer down? I do this with Titebond - otherwise I get visible lines on the finish. How do you deal with that with Unibond 800?
1. The bleed-through blocker is often used with burls, crotches, and open-grain veneers. 2. We do not generally glue the seams. For additional information on seaming veneer, please see our video on veneer tape.
How about CA glue?
CA glues are great for spot repairs, but are generally not used for veneering and laminating.
@@VacuumPressingSystemsInc Thank you for a prompt response! I am aware that they are usable for repairs, but what could stop a random diy-er in using it for larger area veneering, as it ticks all tbe properties boxes?
@@VacuumPressingSystemsInc namely, my first veneering project (an 80-90''s dining table) went awfully wrong, as you described in the video, while using contact cement glue, and I actually repaired ALL of it with using humble superglue (in large quantities), and another coat of lacquer. Therefore I wonder could I use that glue at first place in some future projects?
Fantastic information! Thank you for taking the time to clearly explain the differences.
Great videos, keep up the great work. Super helpful with the stuff im getting into right now, thanks
Oh, one other question? What would be the disadvantage of using two or three platun boards that but together to form one large one to make it easier to lug the boards around and store them when not in use? Any problems with that? Obviously I would take care to make sure the grooves stay lined up with each other while the pressing is taking place. Im building full sized doors so that oviously requires a pretty big board. Thoughts?
Dave in Tampa. I really appreciate all the help over the phone the past couple days. Thanks for sharing your knowledge with me and everyone else. I will fly your flag and promte your business to anyone that is interested. I imagine this video was overdue based on your reaction to my questions about mesh that I based on research I did in other videos. Your reaction was of a little frustration as the info I had gathered and asked you about was inaccurate or incomplete and BAM, here you are correcting the record for me and anyone else who may have been confused by all the same conflicting info out there. Thanks for sharing and doing what you do. In the past three days I have taken on dozens of orders for projects I wouldn't have been able to do a week ago. The vaccuum pressing system opens up so many doors as a woodworker and you are the best out there at presenting clear, concise and accurate info and it is a pleasure dealing with you and your business. Thanks again, Dave.
