Marking out & assembling the body
The first task is to glue and clamp the adjustable
jaws, handle support and moveable jaw pieces
together. Mark out the body piece as shown in
Fig.3. Cut out the hatched section using a circular
saw/bandsaw and use a coping saw to cut the
small 30mm section. You can now glue the 50
× 30mm body insert in place (Fig.5). While this
is drying, mark out the positions for the 10mm
holes in one of the 180 × 30mm body part ‘B’s’
as per Fig.4. When the body insert is dry, turn to
the underside of the body, and mark out and drill
the nail holes as in Fig.5.
You can now nail and glue the 180 × 30mm
body part ‘B’s’ to the body. You will note that
the nails have been positioned so as not to
foul up the holes, which will be drilled later.
You are now ready to drill the 10mm holes.
Centre punch the positions you marked out
previously. If you have a drill bit specifically
sharpened for use on wood, you can go ahead
and drill the holes as it will have a sharp centre
point to locate in the punched holes. If you don’t
have this type of drill bit, you’ll have to drill a
couple of pilot holes. I suggest a 3mm and
a 7mm, then the 10mm.
I made myself a jig to mark out the holes
on the other side of the body. Photo 5 shows
the completed jig. Its dimensions are 90 × x 30
× 27mm. The 10mm metal rod is approximately
40mm long and is placed 15mm (centre) from one
end. The position of the nail is 60mm from the
centre of the rod. Drill a hole for the nail to ensure
accuracy. This jig is used to mark out the position
of the second hole on the moveable jaw so that
it will fit into the body. The aim of this is to ensure
that all holes are exactly the same distance apart,
otherwise the vice/clamp won’t work as desired
and will require some of the holes to be drilled
larger. Next, place the jig into the pre-drilled
hole, use a tri-square to position the jig and then
give it a light tap with a small hammer or your
hand. This will leave an indent from the nail in
the other side. Drill the 10mm holes now. Photo 7
shows the jig being used. Photos 4 and 6 show
the results of the marking out using this method.
If you don’t wish to use the jig you can mark both
sides out as in photo 2 and drill all holes at the
same time. This requires precision in your marking
out as all the holes must be exactly 60mm apart.
