Wood Joinery: Biscuit and Pocket-Hole Technology

As craftsmen build furniture and cabinets the issue of joinery methods hangs within the heads of numerous professionals - every one of them striving to get the perfect joint. For strength, durability, and speed, there are numerous techniques of wood joinery to choose from. The most popular ways of biscuit, or plate joinery, and pocket-hole joinery provide powerfully strong joints in simple and reliable processes. Each technique provides their own group of features to create your joints better.

Biscuit or plate joinery involves the insertion of your biscuit into an oval, or crescent shaped slot that's reduce opposite edges of two items of wood. Biscuits are pre-cut, oval-shaped bits of compressed wood that range in proportions from 1/2in to 2-1/4in in length. There's also biscuits available in plastic, aluminum, and steel for special applications, generally however, wood biscuits would be the most prominently used. Biscuits (dabbed with glue) are inserted into specially cut slots within the wood that are shaped identically to the biscuit, the two bits of wood are clamped together setting, and thus form a solid, durable joint. The biscuits also often soak up the glue placed on them before insertion which in turn causes them to swell making the joint tighter, and stronger. Porter Cable, DEWALT, and Makita each offer top quality plate joiners with unique, and individual features to help meet your needs, and create your joints better.

Porter Cable provides a Deluxe Plate Joiner Kit with a powerful 7.5 amps and 10,000 rpm. This joiner has many features that simplify the joining process, including: a definative micro height-adjustment knob to help keep biscuits exactly centered, and a 1in O.D. (outer diameter) dust port that works with standard bags or can simply hook up with a vacuum cleaner. The DW682K includes a fence tilt of 0 to135 degrees using a positive adjustable stop at 90 degrees; and, for increased cutting control and stability, the bale handle is connected to the fence as opposed to the motor. The joiner even offers a lock-on trigger for continual use plus a supremely accurate (at any angle) hight scale to precisely measure positions. Porter Cable's plate joiner has seven-position rotating depth stop Pocketpussytoy and accommodate many different biscuit sizes and depths, plus a spindle lock mechanism for straightforward blade changes. For normal and face-frame biscuits, Porter Cable's Deluxe Plate Joiner Kit includes both 2in and 4in diameter blades. The kit includes a centering plate, dust bag, a chip deflector, allen wrench, along with a carry bag for portability and convenience.

DEWALT provides a similar Heavy-Duty Plate Joiner with 6.5 amps no load speed of 10,000 rpm; tough enough to exercise even the hardest wood. The DW682K offers a dual rack and pinion system that ensures the blade and fence will almost always be parallel for the most accurate joints - every time. Usually the one piece fence is also adjustable with a 0-90 degree tilt, and, at zero degrees, a flush cut can be made without removing the fence. Additionally, the fence has a locating notch at 45 degrees that enables indexing from the outside surface of a mitered joint: put simply, the fence has a positive lock at 45 degrees to maintain your joints always accurate. The joiner, having a no mar, heavy-duty aluminum shoe, may be clamped as a result of worktops for stationary work - and has retractable, anti-slip pins to assist hold your work in place, and preset depth stops for those common biscuit sizes. DEWALT's joiner kit comes with a carbide blade, dust bag, vacuum pressure adapter, Torx key, wrench, and a heavy-duty kit box for security. The DW682K includes DEWALT's 12 months free service contract, and a three year limited warranty.

Makita also provides an excellent option in biscuit joinery. Their 3901 plate joiner runs on 5.6 amps, with a no load speed of 10,000 rpm. Although with slightly less amps, the tool is powerful enough to make the tight, and lasting joints craftsmen expect from biscuit joinery. Makita's joiner includes a one-touch 6 depth setting that enables for immediate depth change when working, and accommodates most common biscuit sizes. Makita's 3901 also includes a shaft lock for fast, simple blade changes, and easy to use cam locks for added security. Using a cast aluminum pivot fence with positive stops at 0, 45, and 90 degrees the joiner is always accurate and precise, and is also built to quickly and simply make strong and durable plate joints. The tool includes a maximum cut depth of 25/32in, a big top grip handle, no mar rubber strip insert, and is double insulated for more security/safety practical. Makita's 3901 plate joiner carries a carbide tipped blade (4in across), an angle guide, dust bag, lock nut wrench, set plate, inner flange, lock nut, along with a plastic tool case for convenience and portability. The tool is just over a foot long and weighs 6.2 lbs.

Pocket-hole technology involves drilling an angled hole into one workpiece and joining it to a different using a self-tapping screw. This process eliminates tedious drilling applications, and offers a fast, strong joint when the screw acts as a permanent internal clamp pulling and holding two workpieces together. Kreg supplies a Jig Master System created specifically for pocket-hole joinery. The K3MS is effectively two tools in a having interchangeable drill guide blocks that will shift between benchtop and portable bases. The tool has an quick access, spring-loaded, front-side clamp that eliminates reaching around big panels to access your toggle clamps; it keeps everything within arms reach so you can maintain speed and greater ease on the job.

Kreg provides a three-hole drill guide using a hardened steel core that assists you perfectly place pocket holes even in a variety of widths and thicknesses. This steel core also protects bits by continuing to keep them completely covered, and supports work pieces throughout the entire drilling process. This technology reduces bit deflection and tear-out, and supplies a clean, smooth, and pluggable pocket-hole. Kreg's jig also has a fabric support stop that can be set at any distance in the jig helping you to repeat exactly the same pocket-hole numerous times. This stop can also swing or flip dealt with to behave also as a height support for large panels. Additionally, Kreg utilizes an optimized drilling angle specifically configured to improve driving efficiency minimizing the pocket-hole's overall size to lower than 1-1/2in. A wood-chip relief system -which includes one wood-chip relief hole per every drill guide hole - keeps messy debris from your drill bits and reduces drill torque output, thus increasing the life of your drill bits. With this particular system you may create an smooth pocket-hole in a plunge. Kreg jigs are made having an unique composite material that is flexible, resilient as well as strong and durable; each jig can also be built in-part with heavy-duty glass-reinforced nylon that maintains its strength and longevity.

Each one of these joinery options is different and offers professional results and professional strength to your joints. Both biscuit joinery, and pocket-hole joinery offer easy and strong solutions to experienceing this perfect woodworking joint.
