Do wedged tenons need glue?

The logical method would be to glue the shoulders as usual, place the long grain edge of the wedge to the tenon, but do not glue (it may in fact be slightly greased), but gluing the remaining parts of the wedge into the mortise of the stile, making a parallel path for the tenon, but under compression.

What is the purpose of using wedges in tenons?

Driving in the wedges forces the tenon to flare into a fan or dovetail shape. The mortise is tapered to match the angle of each wedge. Like a dovetail, this joint can’t pull apart after the wedges go home.

How do you make a pinned mortise and tenon?

How to make pinned mortise-and-tenon joints.

  1. Cut the mortises and tenons.
  2. Punch a small starter hole at the centerpoint of each pin hole.
  3. Cut the pins from hardwood dowels, normally of the same species Islas the workplaces.
  4. Trim the dowels flush with the leg surface—here we use a flexible, fine-tooth Japanese-style saw.

How do you wedge a dowel?

Leave about at least 3/8″ (or 1/2″) of the dowel sticking above the surface, then split it with a chisel. The extra length of the dowel protruding makes starting the wedge much easier and less likely to break on you.

How wide should tenon be?

Tenon thickness: A tenon’s thickness should be one-third the thickness of the stock being mortised. So, if you are joining two pieces of 3/4″material, the tenon should be ¼” thick (1/3 of ¾). If you are joining a 7/8″-thick apron to a 1-1/2″-thick table leg, the tenon should be 1/2″ thick (1/3 of 1-1/2).

How do you cut a wood wedge?

To cut wedges, adjust the screws to form the desired wedge shape and size. Place the stock into the notch, replace the cover and run the jig against the fence to cut a wedge. To cut the next wedge, flip the stock before inserting it into the notch and running the jig again.

What is pegged mortise and tenon?

Pegged (or pinned) tenon: the joint is strengthened by driving a peg or dowel pin (treenail) through one or more holes drilled through mortise side wall and tenon; this is common in timber framing joints.
