recently I’ve build a cabinet in which a fairly large backwall had to be installed. the cabinet back is 54 inches wide and 88 inches high. it is build in a frame of solid wood. the interior dimensions of the backwall are 47,5 wide by 52 high. the idea is to have a solid backwall with about 4 inch wide boards 1/2 inch thick. since there are no fixed shelves in which I could nail the boards I’m afraid that the width and height are that large that the boards wouldn’t be stable enough. could you give me a hand in:
1. how to make the connections between the individual boards and
2. how to install the boards in the back of the cabinet?
thanks a lot for a detailed answer.
