A: You have encountered a rare situation that is peculiar to white oak. The living tree develops small zones of grayish areas that run across the grain. I believe that they are fungal in origin. They occur at random locations up and down the tree.
In lumber they are confused with sticker stain, except that they are not spaced the right distance apart. In veneer they will run across the face of a veneer sheet. They are typically very faint before the wood is finished. Unfortunately, I do not know of any way to remove this discoloration. Hopefully your veneer supplier will replace the veneers at their cost, but I doubt that they will cover your other losses.
Q: We are having some problems with veneer adhesion to
our MDF substrate. After we have completed the panel and finished
it, we notice delamination (a raised bump) in a few areas in the
center. What should we be looking for?
Q: I'm using some 2-inch-thick lumber to make kitchen
work tops. This wood has some defects, like knots. I cannot
figure out how to use my hand router to cut out these defects in
a curved cut and then end up with two tight fitting pieces. Any
pointers to find which way to do this would be much
The Maiman Co. thought outside the box in developing a line of flush architectural doors.
The companies in this directory are making investments to make sure that you have the tools and products necessary to develop successful products with lightweight panels.
Q: I have read every Wood Doctor column you have written and have gained a lot of practical information. But here is a question I have not seen addressed before. As background, our fairly large company has really gone into JIT, just-in-time, manufacturing, which means in-process materials cannot sit around very long at all. Well, this has recently translated into machining our glued up panels (edge-glued on a clamp carrier) within 24 hours after they are glued, or sometimes less. Of course, you know what the problem is: sunken glue joints that are obvious after finishing. My suggestion of waiting three days after gluing, as we have always done, has not been well-received. I am hoping that you have some help for us.
Avian has reported that its lightweight board meets and exceeds the CARB 2 standards making it one of only a few suppliers of CARB 2 standard boards.
