Bow problem in a conference table
I delivered a conference table to a client a couple of weeks ago. It is a 4 1/2' by 10' table. It is 3/4 pecan with an underlayment of 3/4 mdf, and a 3" wide 8/4 boarder of pecan. They left the table in a hot room stored horizontally (the grain also runs horizontally).
It sits on 2 large pedestal bases.
The problem is that the table has bowed across the 4 1/2' section from end to end. That is to say that the bow goes from short edge to short edge the whole length of the table. It bowed so badly that it actually popped the end borders off, and they were epoxied on.
We picked up the table and brought it back to the shop put it up on saw horses. I took a piece of 2x2 pecan and placed it across the top with a c clamp on each end and was only able to pull about 1/2 of the bow out. So I tried a peice of 1" wide 8/4 going across the 4 1/2' section and there was still about 1/4 - 3/8 gap under each end of the straight edge.
Question is does anyone have any suggestions on how to solve the bow in this table. Right now I am putting the table in the back storage area with clamps and cauls on it till I find a better idea.
