Wood Joinery: Biscuit and Pocket-Hole Technology

As craftsmen build furniture and cabinets the issue of joinery methods hangs over the heads of many professionals - all of them striving to offer the perfect joint. For strength, durability, and speed, there are numerous techniques of wood joinery to select 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 very own group of features to form your joints better.

Biscuit or plate joinery requires the insertion of the biscuit into an oval, or crescent shaped slot that's cut into 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 total. Additionally, there are biscuits for sale in plastic, aluminum, and steel for special applications, generally however, wood biscuits are the most prominently used. Biscuits (dabbed with glue) are inserted into specially cut slots within the wood which are shaped identically for the biscuit, the two bits of wood are clamped together to set, and therefore form a solid, durable joint. The biscuits also tend to absorb the glue applied to them before insertion which causes them to swell to make the joint tighter, and stronger. Porter Cable, DEWALT, and Makita each offer high quality plate joiners with unique, and individual features to help suit your needs, and make your joints better.

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

DEWALT offers a similar Heavy-Duty Plate Joiner with 6.5 amps with no load speed of 10,000 rpm; tough enough to see 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 - each and every time. The main one piece fence can also be adjustable with a 0-90 degree tilt, and, at zero degrees, a flush cut can be made without taking out the fence. Additionally, fences has a locating notch at 45 degrees which allows indexing off the outside the top of a mitered joint: put simply, a fence features a positive lock at 45 degrees to keep your joints always accurate. The joiner, having a no mar, heavy-duty aluminum shoe, may be clamped down to worktops for stationary work - and it has retractable, anti-slip pins to aid hold your projects in place, and preset depth stops for all common biscuit sizes. DEWALT's joiner kit comes with a carbide blade, dust bag, vacuum pressure adapter, Torx key, wrench, along with a heavy-duty kit box for security. The DW682K is sold with DEWALT's one year free service contract, and a three year limited warranty.

Makita offers a great option in biscuit joinery. Their 3901 plate joiner runs using 5.6 amps, and with a no load speed of 10,000 rpm. Although with slightly less amps, the tool is robust enough to make the tight, and lasting joints craftsmen expect from biscuit joinery. Makita's joiner features a one-touch 6 depth setting that enables for fast depth change when working, and accommodates most common biscuit sizes. Makita's 3901 also incorporates a shaft lock for fast, simple blade changes, and easy to function cam locks for additional security. With a cast aluminum pivot fence with positive stops at 0, 45, and 90 degrees the joiner is always accurate and precise, and is also made to quickly and simply make resilient and strong plate joints. The tool includes a maximum cut depth of 25/32in, a large top grip handle, no mar rubber strip insert, and it is double insulated for further security/safety at work. Makita's 3901 plate joiner features a carbide tipped blade (4in in diameter), an angle guide, dust bag, lock nut wrench, set plate, inner flange, lock nut, plus (pocketpussytoy.com) a plastic tool case for convenience and portability. The tool is merely more than a foot long and weighs 6.2 lbs.

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

Kreg supplies a three-hole drill guide using a hardened steel core that assists you perfectly place pocket holes even just in a number of widths and thicknesses. This steel core also protects bits by maintaining them completely covered, and supports work pieces throughout the entire drilling process. Fractional treatments reduces bit deflection and tear-out, and supplies a clear, smooth, and pluggable pocket-hole. Kreg's jig also offers a fabric support stop that can be set at any distance in the jig helping you to repeat the identical pocket-hole numerous times. This stop also can swing or flip dealt with to act also being a height support for large panels. Additionally, Kreg utilizes an optimized drilling angle specifically configured to improve driving efficiency and lower the pocket-hole's overall size to less 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 the drill bits and decreases drill torque output, thus helping the duration of your drill bits. With this particular system you can create an smooth pocket-hole in a plunge. Kreg jigs are built having an unique composite material which is flexible, resilient as well as strong and durable; each jig can be built in-part with heavy-duty glass-reinforced nylon that maintains its strength and longevity.

Each of these joinery options is exclusive and supplies professional results and professional strength in your joints. Both biscuit joinery, and pocket-hole joinery offer simple and strong methods to achieving the perfect woodworking joint.
