I am building a table out of some nasty reclaimed wood. The table needs to be 8 ft or longer, but no boards were 8 ft. So I am building in sections. I have two panels with boards running horizontal, with some boards in the center running vertical. To add additional length I am adding vertical or breadboard ends. I understand that the ends need to be constructed to allow wood movement, but would the center not also have to have this feature as well. I ripped all the boards in the horizontal sections down to 4 inch widths and glued them up, but I expect I still need to accommodate for some movement. The wood is 150 year old pine so I am just not sure what to expect.
As always thanks
