Made 10 end grain cutting boards in two batches. In the second batch, three out of five severely warped. The above photo is a mini one I made out of the scraps that shows the worst of it. The full size ones are not as bad but within the unacceptable mistake range.
Two inquiries:
1. How to prevent this from happening again. My first thought is that one or more of the species were not dry enough. To this end, I think I know what I did wrong. When I bought the rough sawn. Most of it was wrapped in plastic because it was raining real hard, but the two smallest pieces, wenge and Paduak, I put in the cab of my truck. On the way home we picked up the kids and I threw those two boards in the truck bed, in the rain. It was a 5 to 10 minutes drive home, in the rain. It dried of the boards when I got home and left them in the garage, the ones in the plastic were dry. I live in Hawaii and I really don’t worry too much about wood movement due to the weather.
It sat sat for a day, then I jointed and planned the boards. The remaining steps of making end grain cutting boards were done over the course of about 10 days after I came home from work.
They warped in a single day. I did the sanding with a belt sander first, next day ROS 120, next day ROS 220, and next day ROS 320. I know they were not warped at this point, but the next day when I came home from worked they just got crazy. They are cupped, and rather uniformly.
Its eastern maple, walnut, Purple Heart, zebrawood, wenge, and paduak.
2. How do I fix this? I have only a six inch jointer. Not gonna help. Make a planer sled? I have a dewalt 735. Toss the three?
The ones that turned ok, I am happy with. They are all Christmas present and it seems I will need more than 10..
