Preparing for Assembly
These are the short “stretchers” that go along the sides.
The rabbet on the inside is for the plywood bottom to rest on.
Now, up to this point grain orientation on every piece of the case construction is “correct” in relationship to its self. These stretchers on the bottom of the side pieces are the first members that could potentially CONSTRICT seasonal movement of the side pieces.
If I permanently attach these pieces at both ends, the sides will push apart the legs when they expand, and split or pull apart from the legs when they contract.
So to account for this…
- Glue, dowels and one screw at the front end of the stretcher where it attaches to the front leg
- No glue along the length of the stretcher where it rests along the side piece
- Horizontal dowels attach the rear of the stretcher to the back leg by friction only (no glue)
- There is a small gap between the rear of the stretcher and the back leg to allow for movement
- At the front end of the stretcher there is NO gap
Aligning the dowels:
The gap (remember, this will be at the bottom rear of the cabinet so you will never notice it)
Attaching the front legs and stretcher
More dowels will attach the front legs:
After pressing the legs against the dowel aligners and drilling I drilled the holes into the legs. One of the dowels serves a dual purpose… it pins the tenon of the stretcher. How cool is that?
The “pinned tenon” goin’ in:
And it all goes together:
These 3/4” X 3/4” strips will strengthen the top so it is rigid enough for a heavy TV. They act like I-beams. They are glued and screwed to the underside of the top.
And the case is pretty much finished!
