Hi,
I have glued together 3 walnut slabs together to get a 40" x 8ft table top. When I glued it together, there wasn't a cup. Now I have a huge cup. (like 1/2" down from the center on both sides).
I have no idea how this happened or why.
It is changing seasons here, so Relative Humidity is bouncing around some. I had the table outside with a heavy moving blanket on top and draped over the sides for one night. It had a slight freeze that night. The bottom of the table is concave, the top is convex.
I live in Northern Utah. It's dry here year round. I think I'm going o get a MC tool to see if I can find a MC difference in the top of the table vs bottom.
Should I just wait this out? Let it re-balance itself? The table top is 2.25" thick.
thanks and cheers,
