INSTRUCTION FOR USE OF
DOWEL CENTERS
These dowel centers help to make it easy to precisely align the
holes of two pieces of stock to be joined by a doweled joint—
for example, a shelf and each of its supports. They can be used
in conjunction with a dowel jig to show where the joining holes
need to be drilled.
Drill one set of holes with a diameter of 1/4'', 5/16'', 3/8''
or 1/2'' in one piece of stock (see photo). Slip the dowel centers
of corresponding diameter into the holes, with the sharp points
facing out. Then align the two pieces of stock by hand and press
them together. The sharp points will leave marks on the second
piece of stock indicating exactly where to drill the second set of
holes.
To remove the dowel centers, hit the other side of the stock
with a rubber mallet.
