OPERATION

T- JOINTS

See Figure 13.

A T-joint is used when the end of a board is joined to the face of another board as shown in figure 12. Attaching shelves to bookcases and inner support braces to frames are typical applications. Actual cutting of a T-joint is as simple as any other cut. However, it is critical that you mark the centerlines, mark the intersection points for each slot, and cut each slot correctly.

MAKING T- JOINTS

See Figures 14 - 15.

nUnplug the biscuit joiner.

nPlace the two pieces of wood to be joined on a level workbench. The inside face of the vertical board should be facing up.

nDetermine the location of each biscuit joint and mark the centerlines on each board. The centerlines for both boards must line up with each other. Measure carefully; these measurements must be accurate and precise.

NOTE: Measure twice and cut once. In addition to the centerlines lining up, the spacing of the biscuit slots from side-to-side must also match.

nPlug the biscuit joiner into the power supply and cut slots in all boards that require end slots.

Follow the procedures explained in “Edge-To-Edge Joints.”

nSet the fence angle at 90°

nSet the fence height at the desired dimension on the scale.

nSelect the correct depth of cut setting for the biscuit size you plan to use.

nClamp the workpiece securely, then cut each slot at the marked centerline intersection.

Next, you must adjust the fence on the biscuit joiner in order to cut slots into the face of the vertical board.

JM82 specifications

The Ryobi JM82 is a versatile and compact jigsaw, ideal for both DIY enthusiasts and professional woodworkers. Known for its powerful performance, the JM82 combines modern technology with user-friendly features to deliver precision cutting in various materials.

One of the standout characteristics of the JM82 is its 7-amp motor, providing ample power for cutting through wood, plastic, and even metal. The variable speed control allows users to adjust the cutting speed from 0 to 3,000 strokes per minute. This feature is essential for matching the cutting speed to the material being worked on, ensuring smooth and efficient cuts.

The JM82 also boasts a unique orbital action, offering four different setting options. This orbital feature enhances the cutting efficiency by allowing the blade to move in a circular motion as well as up and down, effectively reducing the resistance and enabling faster cuts in thicker materials. This level of customization empowers users to tailor their cutting techniques to specific tasks, ranging from intricate curves to straight cuts.

Another notable feature of the Ryobi JM82 is its tool-free blade change system. This mechanism allows users to quickly and easily swap out blades without needing additional tools. The ability to change blades effortlessly enhances productivity and convenience, especially when working on projects that require different blade types for various applications.

The integrated laser guide is another remarkable technological advancement in the JM82. It projects a clear line on the workpiece, ensuring precise alignment and professional-grade results. This feature is particularly useful for intricate cuts and patterns, maximizing accuracy and reducing the likelihood of mistakes.

Ergonomics is a key focus in the design of the JM82. The handle is designed with a soft grip, providing comfort during extended use and minimizing user fatigue. A built-in dust blower keeps the cutting line clear of debris, improving visibility and ensuring clean cuts.

In terms of build quality, the Ryobi JM82 is constructed with durability in mind. The sturdy design and high-quality materials ensure that the jigsaw can withstand rigorous use while maintaining its performance over time.

In summary, the Ryobi JM82 is a powerful, feature-rich jigsaw that caters to a wide range of cutting needs. With its adjustable speed, orbital action, tool-free blade change, integrated laser guide, and ergonomic design, it stands out as a reliable tool for any woodworking project. Whether you're creating intricate designs or making straight cuts, the JM82 delivers precision and performance, making it an essential addition to any toolbox.
