I’m working on a table top and wanted to get some advice on whether any horizontal bracing would be necessary to prevent future warping.
The table top will be about 78″ x 40″ and made from walnut boards, which range 6″ to 8″ wide and have been planed to 1.75″ thick. I’ll plan to glue them up, with biscuits used for alignment.
I don’t think breadboard ends would work for the style of table I’m going for, but I was thinking about routing a space underneath to insert a steel C-channel, which would be screwed into the table at different points (only fully tightened in the middle to allow for movement).
The question – is the added brace needed to keep the table flat or is that overkill that I could avoid?
