Morticing Guide
Paul
Sellers created a set of saw guides with different offsets for the
beauty shoulder. My version is similar, with a few exceptions:
(1)
The fixture adjusts for any offset (it is not a fixed distance from
the edge), replacing several fixtures with one.
(2) It is held in
a face vise, but the chopping takes place on the bench (in my case,
over a leg). Paul chops his in the vise (not so good for the life of
the vise?).
(3) The fence also acts as a hold down, preventing
the work piece to be lifted by the mortice chisel.
The front
..
The
rear …
The
fixture is simply a long fence with a fine sandpaper as non-slip,
against which the stretcher is clamped, and a short sliding fence,
which will act as the depth control.
The marked mortice ..
Place
the stretcher on the bench and drop the fixture on top of it. Clamp
the fixture in the bench …
Now
adjust the sliding fence alongside the registration side of the
mortice …
Clamp
the stretcher against the long fence and begin chopping with the
chisel against the sliding fence ..
The
aim here is to achieve perpendicular sidewalls.
Another
way to use this fixture is to drill out the waste, and use the
sliding fence to pare the remaining waste ..
