I make a lot of things using large slabs of wood. Tables and such. I just got two pieces of bookmatched walnut that are 96” long and 18”wide, about 3” thick. I usually dont have much trouble with those, but here lately I’ve been getting lots of requests for Pecan cutting boards. I made a few on request, then a few more, and now I have 22 pending orders.
I have a source to get these big pecan slabs, live edge of both sides, 8ft long, 12-16” wide, and 2” thick. WEll the Pecan really likes to cup and check and get bumpy as it cures, these slabs were cut green and sticker stacked. They were cut back in February, and it rained almost every day until June, but has bene dry since. They are kept outside, but under a tarp.
This last slab I got, I took to a guy who has a huge 24” planer, looks like a Zamboni, and he planed them out flat for me. took them down to about 1.5” thick, then I took them home and cut out a dozen cutting board blanks or so. Ive had them stacked up in my garage and have been working though these orders since June 29th.
I noticed yesterday that most of what I have remaining have cupped really bad, to the point that I probably cant use them. a few probably have a 1 inch cup on a board 12” wide. If I planed it out, theyd be less than a half inch thick. I dont mind a little cup, I just put that side down, these are raw cutting boards so they don’t have to be perfect.
So what can I do to prevent this cupping? Do I need to start keeping the blanks inside, out of the heat? I figured since they are mostly dry, the heat wouldnt be an issue, they’ve been outside since it was cut.
