The same rules apply, nevertheless: Once you veneer one facet of a piece of wood, you have to veneer the other side too, or else the piece might be pulled concave towards the veneered side as the glue dries. When veneering plywood, always cross the grain path of the face veneer and of the bottom layer. You should use some angle other than 90°, as long because the grain of the veneer and the grain of the highest layer of plywood don’t run parallel. When the tree is damaged, many of these dormant buds are referred to as to action and they create a chaotic grain pattern that successfully patches the damage. A burl is often just nature's approach of creating a band-aid. If you have ever tried to break up a burl with a wedge, you understand how strong the interlocking grain will be. Some burls such a madrone, redwood, maple, and buckeye develop under floor stage or at the root crown (right at the bottom floor).
The unorganized grain in burl wood is beautiful but horribly susceptible to warping and splitting. By slicing a burl into veneer, wooden movement is saved below control by the adhesive and substrate. Even probably the most unruly woods can be sliced into veneer and used to make a gorgeous, yet stable panel. Economy & Availability - Many wooden species are so uncommon and valuable that in lumber form, are simply unaffordable. There's a marked scarcity of nice logs accessible world-large. Couple this with the thought that there is an ever-rising demand for nice wood and you've got a formulation for a log that's price ten occasions what it was 5 years ago.
On this case, you'll be able to press each sides at the identical time. Merely apply the glue to the again facet of the substrate and lay the backer veneer onto that surface. Then rapidly transfer on to applying veneer glue to the face side of the panel. Put the face veneer in place and get it below clamping pressure as quickly as possible. Press the panel for 60 minutes or as described on the veneer glue instruction label. A vacuum press is the ideal instrument for шпонирование clamping veneer to a substrate as a result of it applies a major amount of even stress distributed across your entire floor. For those who should not have a vacuum press, you'll be able to normally get a very good completed panel with clamps and weights. The bottom line is to verify the strain is evenly distributed.
Then, insert the challenge into the vacuum bag. Seal the bag and use the hand pump or electric pump to remove the air. It's Ok to glue up multiple venture at a time if they'll all match into the bag. Once the glue is dry, release the vacuum inside the bag and remove the venture. (Image: https://restavraciy.ru/mk/shpon/008.JPG)
