TESTER’S TAKE: Though the kit is remarkably
easy to use, the cutter will require sharpening with
extensive use. I found it fun to use contrasting species
such as walnut dowels on maple projects. Two things
to keep in mind when threading dowels are to oil the
threads before screwing the dowel into the hole (or
it will never come out!), and also to thread a long
dowel and then cut it off close to the threadbox, so that you don’t have
reverse the cutter along the part that
you want to keep.

THE TEST: Now, secure the workpiece in a wood
vise or elsewhere, slip the T-handle in the tap, and turn
the tap clockwise into the hole as shown in Photo C. It’s
important that the tap is vertical to begin with. Unlike
the threadbox, reverse the cutting motion constantly to
clear chips. A little oil goes a long way here. Bottoming
taps, sold separately, are available for cutting threads all
the way down to the bottom of a blind hole.
BEST APPLICATIONS: The Wood Threading
Kit proves ideal for making antique planes, handscrews,
bar clamps, vises, and veneer presses. In the world
of home furnishings, you’ll see threaded parts used
in adjustable candle and music stands, novelty boxes (having wooden nuts and
bolts), tabletop nutcrackers,
knockdown furniture, and toys.
