Spur Dogs for Clamping Miters
H
ERE IS A METHODthat allows you to clamp up mitered edges.
The method is based on a spur dog, a device that provides a
perch for C-clamps and spreads clamping pressure evenly over the
joint. To make the dogs, cut several pairs of 3-in. sections from a
length of 1-in. angle iron. In each section, hacksaw two^5 ⁄ 16 -in.-deep
slots about^1 ⁄ 2 in. from each end of one side. Bend the two tabs down
about^3 ⁄ 32 in. and file the spurs sharp, as shown in the sketch above.
To use, spread glue on both faces of the miter and press together
for a light tack. Tap the two (or more) dogs into place and clamp. The
spurs enter the wood grain about^1 ⁄ 8 in. and therefore leave small scars
on the wood. These scars can be removed by rounding over the cor-
ner, or they can be closed up some by steaming.You might decide to
simply tolerate them.
