The Project: V4™ vacuum press uses your air compressor to create vacuum for veneering and clamping. This system automatically shuts off air flow to the vacuum generator (also known as a venturi) when the desired vacuum level is reached so your compressor does not run continuously. No modifications are done to your air compressor. The flow of compressed air stops when adequate vacuum is created within the V4 system. Your compressor will only turn on as pressure is needed to refill its air tank.

What is so great about the Project: V4 vacuum press kit?
The Project: V4 system is designed for quick and easy asssembly. The most significant change is the very sturdy carrier assembly. The kit now includes this vital part. In fact, everything you see in the pictures is included with the kit including the PVC reservoirs. I've also simplified the wiring (now 12v DC) and the vacuum assembly. The system now also includes a vacuum filter and our new quick-connect vacuum fittings.

Project: V4™ Features
The Project: V4 system will create vacuum slightly faster than previous versions of our venturi system due to an improved pneumatic design.

Venturi WarrantySimplicity: The entire system can be built in less than 2 hours. You will find the process of building your own vacuum press very rewarding. No soldering or advanced electrical skilll is required to assemble the system. The electrical wires have the connectors already attached!

Strength: This system is designed around a very powerful venturi which is capable of creating up to 25.5" of Hg at sea level. The venturi comes with a lifetime warranty.

Vacuum Storage: The vacuum valve allows the system to be pre-charged with vacuum to increase the initial pull down speed.

Adjustability: The vacuum controller has an adjustment screw that allows you to dial in your desired level of vacuum. You'll find that 21" of Hg is ideal for most veneering projects. The system is adjustable from 10.5" to 25.5" of Hg. An alternate vacuum controller for low vacuum applications is available here.

Air Efficiency: Our venturi units are precision-milled in the USA using specifications exclusively for this system. This means even smaller compressors can pull down average size vacuum bags. If you are concerned that your air compressor is not strong enough for a V4 system, you may find this link helpful.

Electrical Efficiency: The Project: V4 system runs on 12v DC and uses less than 6.5 watts at 12v DC when the system is recharging vacuum. There is no electrical consumption at all when the V4 system cycles off. Keep in mind that the electrical consumption of your air compressor will vary.

Quality: The Project: V4 system uses nearly all brass components. No flimsy plastics or cheap stamped metal parts are used.

Non-Proprietary Parts: Most of the parts used on this system can be readily found on the Internet or at your local hardware store.

Why does the V4 kit cost more than the V2 kit?
The V2 kit requires approximately $60 worth of additional items from the hardware store to complete the system. The V4 kit includes these items (PVC pipe, PVC caps, power plug and more) as well as a vacuum filter and our quick-disconnect hose assembly. The V4 kit also includes the carrier assembly.

Kit Version Project: V2™ Project: V4™ V4 Difference
$245.50 $255.50 $10.00 More
Basic™ $245.50 $255.50 $10.00 More
Plus™ $255.50 $265.50 $10.00 More
Premium 5™ $328.00 $314.50 $13.50 Less
Premium 9™ $356.00 $349.50 $6.50 Less

What does "beta model" refer to?
These are systems which have already been assembled and tested. These units may not represent the final kit that will be introduced in the coming months.

When will the Project: V4™ kits be available?
We expect to begin shipping V4 kits in early to mid July.

If the other system is called a Project: V2, then why is this not called Project: V3?
We did have a Project: V3™ kit a few years ago but one of the key component suppliers went out of business. It was a short-lived system in which I may have only shipped 20 to 30 units. If you are one of the lucky few that has the V3 system, you've got a great tool in your shop!

Will this system have enough force to bend strips of wood so I can make bent laminations?
This is a difficult question to answer because it depends on many factors such as thickness, species and grain direction. It will also depend on the radius and complexity of the curves that are being used on the project. At sea level, a vacuum press can create up to 1,750 lbs of clamping pressure per square foot. You will need to decide if that is enough for your bending project.

How does my altitude affect the maximum vacuum level of this system?
There is a loss of approximately 1" of Hg for every 1,000 feet above sea level. For example, at 5,000 feet above sea level the most vacuum this system will create is 20.5" of Hg. The generally accepted minimum for vacuum pressing a veneer is 17" of Hg.

What can I do if my air compressor falls short of the requirements for the venturi?
The system will not work if your air compressor can not create the required air flow for the venturi. In this case, the venturi will only achieve partial vacuum.

Why don't you include the kit instructions with the kit?
It would be too wasteful to print copies of the instructions. Most people have already printed and read the instructions before they order... something I highly recommend.

How much does the system weigh?
The complete system weighs approximately 18 lbs.

What power source is required?
The Project: V4 kit requires standard US 120v AC. The system uses a power adapter to supply the system components with 12v DC.


Product Reviews

  1. Great Press, Excellent Value, Highly Recommended!

    Review by Jeff Kusama-Hinte

    I generally make solid wood furniture but, occasionally, I have the need to apply shop sawn veneers. For years I have used clamps and cauls — which are always cumbersome and rarely deliver perfect results.

    I purchased this press a couple of weeks ago and it has performed flawlessly. The device is well designed, very reasonably priced, has high quality components, and it is a pleasure to use. I am so happy that I chose a venturi pump model as the last thing I need is another motor humming away in the shop (my compressor is in a sound proofed room far from my bench); the only sound it makes it the release of air as it forms a vacuum.

    The customer service has been fantastic — it shipped quickly, for a very reasonable fee, and my questions were answered promptly. I received one of the Pre-Assembled Prototype Kits so I didn’t assemble it myself, but I suspect that it would be a very straightforward process for anybody that was minimally mechanically inclined.

  2. Works Great

    Review by David Giasson

    Vacuum press works great and is easy to use. The delivery was fast and customer service great. I have enjoyed working with Joe and ordering the excellent products he offers.

  3. Very happy with this product

    Review by Alex Parker

    Fantastic tool. Works great, easy to set up and use. The “Basic” level venturi is plenty to operate a 2x4 foot vacuum bag.

  4. Best Tool in My Woodshop

    Review by Dylan Standridge

    I am very new to wood veneer and the process of veneering and buying this unit was the best choice I could have EVER made. This vacuum press kit is so well made and there is nothing to do. Just take it out of the box plug it in and go. This allows me to concentrate on the project and not the equipment!
    This has become my new favorite tool in my woodshop!

  5. Fantastic Kit with Impeccable Customer Service

    Review by Anthony Myers

    I'll start by writing that Joe did ask me to write this review for his website but I don't mind doing it because a) the V4 system is incredible and b) Joe has been exceedingly helpful throughout this learning experiences. I'm actually writing this review while my third project is being pressed.

    I ordered the premium 5 version and had it FedEx shipped to my house. The shipping charges seemed fair to me considering the weight and size of the box. The package arrived three days after I ordered but I know it shipped within 5 hours of putting the order through this website. That is impressive and it just goes to show what kind of business this is. I could not be happier with this kind of service.

    Now on to the V4 review. Since my system is prototype (aka beta) model it was already assembled by Joe before shipping. I suspect the full assembly instructions will be impeccable. If you haven't seen his other vacuum press instructions then you should take a look because they are very well written. The V4 system is fairly compact considering what it does. It weighs less than 20 lbs but the handle grip is comfortable and balanced well on the system carrier. I first tested the unit by keeping the valve closed and letting it charge up vacuum and then cycle off. The system held with no leaks for 14 hours. After that I was just too excited to use it and couldn't wait any longer. My first project was with a 4x4 vinyl vacuum bag and the project was tiger maple veneer on a 3/4" thick piece of cabinet grade plywood. The V4 kit can be pre-charged with vacuum as I mentioned so the initial vacuuming of the bag is quick. The system required compressed air for less than minute to get the bag to 21" hg. My compressor did come on during the time but it ran for no longer than a normal "on" cycle.

    The V4 system is run off of 12VDC which is a departure from the V2 system which was 120VAC. This has no impact on the performance of the vacuum press but I thought it was worth mentioning. Overall the system has a sort of grass roots feel. It kind of looks homemade but definitely better than most people could actually make on their own without knowing the complexities of what is going on with the various parts. The machining of the plastic carrier is outstanding and it appears that the parts of the system all fit perfectly on the carrier. The parts of the setup are good quality. For instance the brass fittings - they look better than hardware store Chinese brass parts. You can tell simply be the surface appearance of the brass. The hose assembly is rugged and the vacuum gauge appears to be stainless steel.

    There is nothing I would suggest for improving this system. If you are thinking about getting into veneering then I highly recommend this system. You won't find better customer support anywhere else!
