Exposing Vacuum Press Veneering Myths
It is common for bad information to spread like wild fire over the Internet, TV, and other media sources. Just like topics regarding health and finance, myths have also been spread about vacuum press veneering. Some of the common myths are exposed below.
Myth: Water-based glue will cause ripples in my finished veneer panel.
This is not true. Ripples are caused by using too much glue or not using enough pressure while the glue is curing. The use of water-based glue alone will not result in ripples.
Myth: Thinner veneers are more difficult to work with than thicker veneers.
Thicker veneers may appear to be easier to sand smooth, but in actuality they are difficult to keep flat when in the shop environment. They are also prone to the cold creep phenomenon, so it is essential to use a stronger adhesive than ordinary glue, such as plastic powder resin glue.
Myth: A vacuum press is too difficult to build.
Many people have had success in building a vacuum press. Black Bros.Company can create vacuum presses based on your needs and the nature of your job. It is most important to choose the right version for you to build, and this depends on several factors:
- >Will the projects that you make primarily be curved or flat?
- >What is the largest project size you anticipate that you will need to place into a vacuum bag?
- >Are you interested in a continuously running system or one that cycles on and off automatically?
- >If you want a press to cycle on and off, would you prefer it to be compressed air or electricity powered?
Myth: Special adhesives are needed for oily veneers.
This is not true. Oily woods can be wiped down on the glue-side with naptha, and then the glue can be applied as normal. Many oily woods like teak and rosewood can be treated in this manner and veneered without any problem.
