Mortise and Tenon Joinery – Using Only a Hand Drill!
Mortise and tenon joints
are the gold standard for
strength. Usually, mortises
are cut by hand or made
on a mortising machine.
Two jigs by beadLOCK
make this much simpler
and less expensive: all that’s required is a hand drill.
Here’s how beadLOCK works. First, you use a beadLOCK jig
to drill a series of overlapping holes in both sides of a joint.
Second, you cut beadLOCK’s tenon stock to fit the mortises.
The whole process is easy and accurate. The unique shape of
the tenon stock adds up to 10% more gluing surface.
The basic kit includes a 3/8 in. drill bit, stop collar, and a 3/8
in. guide block, allowing you to center a mortise 3/8 in. from
an edge. Using shims, you can center the mortise up to 7/8 in.
from an edge.
The Pro Kit is based on a newly designed drilling jig and
includes everything needed to make 3/8 in. joints. It handles
stock up to 3-1/2 in. thick and makes mortises up to 3-1/2 in.
wide. The drilling block slides on guide bars, allowing much
more flexiblity than the basic kit in positioning a mortise. The
new jig also enables you to make square mortises. You drill the
holes as usual, replace the drilling guide with a straight-sided paring
guide, and use a chisel to square the mortise. Kits for making
1/4 in. and 1/2 in. mortises are available for both models.
