The side panels should be fitted into grooves in the rails, and before the frame is put together these panels should be squared up and the grooves cut in the rails and posts at the proper places.

Details of Hall Clock
The mullions of the lower side panels, it will be noted, are specified 5/8 and 3/4 in. wide. The 5/8-in. pieces are for the central parts of the frame and the others for the outside. The frame is to be made 1/8 in. larger all around than the distance between the posts and between the rails so that it may be set in grooves cut in the posts and the rails to a similar depth, 1/8 in. This is true, also, of the mullions of the front doors. Square up the shelves so that they may be set into grooves in the adjacent rails. The middle shelf is to have an overhang and will rest upon the rails.
The mullions of the top side panels are all of the same width, and it is not intended or necessary to set their frame into grooves in the posts. The wood panel back of them gives ample strength.
