CRAFTSMANSHIP


String and nail clamp
If the parts of a glue-up are too awkwardly shaped to hold in
place using the regular clamps you have to hand, then you
might like to consider tapping in a nail either side of the glue
line and pulling the parts together by winding string around
them. This improvised clamping method is not only adaptable
and quick to set up, but is also easily adjustable.
In this example a simple butt joint repair to a strut is
clamped under gentle pressure and in perfect alignment
using string wound between pairs of small nails until the
glue sets. Small holes left by the nails are easily filled
and painted over.

Paring to the line
A sharp bevel-edge chisel is a highly versatile tool, tough enough to
chop out a mortice yet fine enough to clean the corners of a dovetail
joint or, as here, the perfect tool for paring down to the line in a
situation where even a bull-nose plane cannot finish the job. The
technique is to push with one hand while the other holds the blade
flat to the surface and also applies the brake, enabling you to sneak
right into a corner taking very fine shavings with excellent control
and visibility. Raise the pushing hand slightly to take a coarser
shaving, and skew the chisel to make a cleaner cut. Used in this way
it’s also handy for paring away glue squeezed from joints and cutting
wooden plugs flush with their surroundings.

STORY AND PHOTOGRAPHS


ROBIN GATES


When you need to cross-cut a piece of timber
squarely but you don’t have a try square to
hand, lay the back of the saw across the
face of the timber and adjust its position
until the edges of the timber are in line
with their reflections in the saw plate. At
this point the saw will be at right angles
to the edge of the timber and you can
mark your line. Working by eye in this
way is surprisingly accurate – the saw need
be only a degree or two out of square for
the timber and its reflection to be clearly out
of alignment. The shinier the saw, the better this
works, so give it an occasional wipe with an oily rag
to keep the rust at bay.
