SPECIFICATIONS
●
Both of the cutters, 45° and 90°, can easily be adjusted to cut approximately 1” diameter up
to about 3” diameter tenons at the ends of logs and branches.
●
Both the 45° and 90° cutters fit onto the same shaft. The shaft has a flat side on the drill-end
to prevent slippage during use.
●
The maximum log diameter that the cutters will accept is about 4-1/2”. If you have a slightly
larger diameter log, you can shave it down at the edges by using a draw knife, shave,
manual or electric hand planer, or a saw so that it will fit into the cutter.
●
The maximum tenon length is about 2”, which is usually more than adequate. Take a look
at the
section to learn how to measure and cut log lengths for curves.
●
The E-Z 45° Log Tenon Cutter uses one blade to cut a tenon, which is mounted on the
cutting arm and ready to use. There is also a spare blade which is stored on the non-
cutting arm. The E-Z 45° cuts a 45° shoulder on the sides of the tenon.
●
The 90° E-Z Log Tenon Cutter uses two blades to cut a tenon, one on each arm. The 90°
E-Z Log Tenon Cutter will produce a flat 90° shoulder on the sides of the tenon.
●
The cutting blades are made from hardened steel, and have a cutting edge on both sides.
Each blade is like having two blades. When one side gets dull, use the included Allen
wrench to remove it and flip it over to use the other side.
●
The blades for the 45° and 90° cutters are not interchangeable. The blades for the 45°
cutter are slightly longer than the blades for the E-Z 90° Log Tenon Cutter. If you need to
order replacement blades please be sure to order the correct size, and remember that the
90° uses two blades to cut a tenon, while the 45° only uses one blade.
●
A pilot hole must be drilled into the end of the log prior to cutting a tenon. A 3/8” Drill Bit is
included to drill the pilot holes.
●
The E-Z Log Tenon Cutters will fit into any 1/2” drill. We recommend using the highest
powered drill you have with a side handle extra support.
●
The drill guide inserts into the pilot hole to guide the cutter. This will help hold your drill
steady to create a perfect tenon.
●
One 3/32” Hex Key is included to adjust tenon diameter, switch cutting arms, and to switch
bushings on the E-Z Log Sink (Countersink) bit.
●
One 3/16” Hex Key is included to install or replace cutting blades.
●
Two of the most popular sized bushings are included with the E-Z Log Sink. One is used to
countersink a 1.5” mortise, and the other to countersink a 2” mortise. Both bushings can be
attached to the Sink during use by tightening the set screws. The E-Z Log Sink is not a drill
bit. You must first drill the mortise.
●
A 3/8” drill bit is included to drill the pilot holes at the ends of logs and branches.
●
A printed copy of this Product Manual is included with your order. Save your printer ink!
●
Two free woodworking plans are also included with your order. One is to build your own
strap clamp from scraps of wood. The other is to build a Center Finder so that you can
easily find the center of the log when drilling pilot holes.
