Pictorial views of marking out 15

of joinery- items – unless designers want to highlight
non- standard or complex detail – but they serve their
purpose here to explain the setting out views shown at
(b) and (c) above.


PICTORIAL VIEWS OF MARKING

OUT

Figures 2.11(a)(b)(c)(d): There are a few variations in
marking out handmade joinery items – apart from
those that naturally exist between handmade and
machine- made products. In the latter case, if using a
tenoning machine, only the end grain of one of the
rails needs to be marked with the mortise gauge, so
that the tenoning- block cutters can be adjusted and
set to the tenon- thickness and the tenons’ vertical
position. My reference is to variations in marking out
for handmade items. To highlight this, the pictorial
views below reflect textbook marking out for hand-
made joinery – which could be followed. But where
I have shown dotted lines (depicting the tenon’s
haunch- reduction and haunch projection), I main-
tain that this marking out and these cuts would best
be made on the actual tenons, after they have been
deeped (rip- sawn), the shoulders cut and the cheeks
exposed. Note that the underside of the tenons,
denoted by the dotted lines on the face- side edges,
will be automatically formed by the panel- grooves
(before the tenons’ cheeks are exposed).

giving door- height, position of middle rail and positions of
the five mortises required for the three rails.


Figure 2.10 (d) Outline views of sections A- A and B- B
(detailed at 10(b) and (c) above), as they would be set-
out on a ‘door rod’ of thin plywood or hardboard, etc;
note that the top rail is lined- up with the left- hand stile (or
vice versa); this is usually done to create speedier squar-
ing/setting out of components with identical detail.

Figure 2.11 (a) Marking out of mortise, tenons, haunches
and panel- grooves on face- side and face- edge of top
rail; and (b) marking out on back- side and back- edge
of the same rail. Note that this marked- out rail is usually
G- cramped to the other unmarked rails and used as a
‘rod’ or ‘pattern’ for squaring and transferring the estab-
lished marks across the face- edges. The rails are then
separated to complete the marking out.
