Carbon Fiber Stiffened Warpless Walnut Tray??

I wanted a solid, not glued up, walnut tray, but of course it warped like crazy. I’ve been playing just a bit with carbon fibre, so I decided to flatten the tray it back out with clamps and laid unidirectional carbon fiber in epoxy in 3/8” deep 1/4” groves.

Any one tried this? Think it will hold up to Boston’s fluctuating humidity??

Interesting experiment. Carbon fibre masts are very strong but are meant to flex a little…..
Keep us posted.

Another way to remove the warp or cupping is to rip the wide board into three pieces, joint the edges and re glue them making sure that the grain goes back the same. The result is an invisible joint and a flat board.
Like Paul said, keep us posted on your results.

Carbon fiber tubes and bars are common in guitar bass necks with five or more strings, used in conjunction with truss rods. I use CF alone to build double bass necks. (no truss rod) The tube is epoxied in the groove and caped with a timber filet to avoid sanding CF and inhaling very toxic dust.

my guess is cross grain, no. A glued up board won’t cup?

-- if it is to be it is up to me
