I am a novice woodworker, and have made most of my projects on inexpensive pine. I recently decided to make a table that I found in Anthony Guidice's book "Tables". I recently bought and dressed about 25 BF of nice curly maple....but I still cant bring myself to use it until I am comfortable with what I am doing.
The project called for cherry, but I am using soft maple I got from a local ("reputable") lumber yard here in New Hampshire (again I went the cheap route). It was kiln dried 6-8%......... I let it sit in my workshop in the basement for a couple of days. I jointed and planed the 4/4 lumber down to 3/4" and glued up my top....making sure to alternate growth rings as I have read. I used (3) 8" wide pieces. The finished top will be about 20" square. I let it sit for about 24hrs clamped, and set it aside to be cut down later. a week later the damn thing has huge cup in it! there is about 3/4" gap between the table top bottom and the bench top. Did I not let it acclimate long enough? Should I have used four or five boards to create the top rather than the (3) I used? Any help would be greatly appreciated!!!
