Hello everyone,
I apologize if this isn't the correct part of the forum for this post, but I'm desperate.
I'm manufacturing products out of bamboo plywood (http://www.calibamboo.com/bambooplywood.html)
My products are basically flat boards with an assortment of pockets cut out of them. After the boards have been milled, they all warp terribly. The ends of the board cup/bow towards the side the milling was done on.
The warp seriously diminishes the quality of the finished product. Does anyone know of a way to prevent or fix this?
I've tried wetting the opposite side of the board and letting it dry/flatten with no success.
Any help is greatly appreciated!
Nick

Have you checked moisture content prior to cutting?
Here are notes from another bamboo plywood manufacturer (Plyboo):

Here is a link to another forum where someone was encountering similar issues. (->Link) You might contact Steve to see what he found for a resolution.Plyboo panels are manufactured to an average moisture content of 6 to 9%. However, due to
environmental conditions, the product you receive may vary. It is recommended that before
working a panel that a moisture reading be taken. If acclimation is necessary this should be
performed prior to working the material and should take into consideration the environment and
the application at the final installation point.
Plyboo bamboo panels, like wood products, will expand and contract with changes in relative
humidity (RH). The greater the seasonal change, the greater the potential for movement.
For best performance, a temperature range of 45–75 degrees Fahrenheit, and a relative humidity
of 35–65%, should be maintained throughout the year. In areas with a wide seasonal variation in
RH and temperature, every effort should be taken to adhere to the recommend ranges.
Exceeding these ranges can result in unwanted movement and including checking, cracking and
warping in some cases.
