Tapered Tenon Cutters
U.S. Des. Pat. D547,155
The body design of the Veritas? Tapered Tenon Cutters is similar to the Veritas?
Dowel and Tenon Cutters; however, the straight-edged high-carbon steel blade will
put tapered tenons on the tips of turnings, dowel or rustic furniture components to
fit into tapered holes, such as on the legs and spindles of a Windsor chair.
Available in five diameters, 3/8", 7/16", 1/2", 9/16", and 5/8". The sizes are the
minimum diameter of tenon the cutters will taper; the maximum is 1/2" greater,
over a total tenon length of 21/2". A starter set of the 3/8", 1/2" and 5/8" sizes will
cover most tenoning requirements for typical chair making. If you have all five
sizes, you will be able to cut tenons up to 11/8" in diameter and as long as 2".
Works equally well in soft, green or hard woods.

Making Tapered Tenons
The cutter works much like a
hand-held pencil sharpener; you
either rotate the workpiece while
pressing it into the cutter body
or you can rotate the tool on the
In most instances, the tenon
produced should be concentric with
the rest of the workpiece. To help
achieve a properly aligned tenon, x
keep the workpiece centered in the Figure 2: Workpiece aalliiggnnmmeenntt..
infeed, as shown in Figure 2.
Caution: Do not use these cutters with a power feed to make dowelling,
as sustained use will lead to extreme heat build-up and the bodies of the
cutters will become extremely hot.
In some cases, such as with tenons longer than 2", you may need to first cut the
tenon to the required length and major diameter with a larger size cutter, then
make a second pass with a smaller size cutter. (See Figure 3.)

Caution: Be aware that the blade is sharp; careless handling can result
in serious injury.
Since different wood species and conditions yield different results, you may need
to adjust the blade accordingly. Always make a test tenon with a scrap piece of
wood of the same material as your workpiece, then check the diameter of the
tenon by test fitting in a hole of the same size.
The blade is retained with two screws. A 1/8" hex key is provided to loosen or
remove the screws for blade adjustment or removal. (Be aware that the hex nuts
are not captured and will fall out when the screws are removed.) The blade bed has
index lines to help judge the blade's position and relative movement.
If shavings clog the mouth, start with the blade further out. It may be necessary
to skew the blade to achieve the desired taper without clogging.
The high-carbon steel blade is supplied with a 30? bevel. As supplied, the cutting
edge is adequate for rough work in most woods; however, accuracy and surface
finish will be improved with additional sharpening.
Start by lapping the back of the blade and then proceed to honing the bevel. A 1?
to 2? micro-bevel honed on the final edge will strengthen the edge and reduce your
