OPERATION

MAKING EDGE MITER JOINTS

See Figures 19 - 21.

nUnplug the biscuit joiner.

nPlace the pieces of wood to be joined on a level work- bench.

nMark the centerline of the joint on each board.

nWhen making edge miter joints with workpieces that have different thicknesses, clamp the pieces securely to a workbench with the long sides up. This will assure that the outside surfaces will match.

nLoosen the locking knob and set the fence angle at 135°.

nSet the fence height at the desired dimension on the scale by rotating the height adjustment knob.

nTighten the locking knob securely.

nPlace the biscuit joiner on the workpiece with the adjust- able fence resting on the long side of workpiece. The base or vertical fence should be against the mitered edge of the workpiece.

nRecheck the fence height setting to make sure it will not cut through the workpiece.

nAlign the indicator mark on the fence with the centerline on the workpiece. Make sure the base or vertical fence is pressed flat against the mitered edge of the workpiece.

nPlug the biscuit joiner into the power supply and prepare to cut the slot.

nDepress the switch trigger to turn on the biscuit joiner, then push it forward to extend the blade into the wood.

nWhen the base assembly bottoms out against the depth of cut adjustment knob setting, pull back, releasing pres- sure on the spring. The blade will retract from the biscuit slot.

nRepeat this procedure for cutting the mating slot and all required miter joint slots.

nOnce all slots have been cut, place a biscuit in each joint and dry-assemble the workpieces. Make sure each joint lines up and fits.

nFinally, disassemble workpieces and place a bead of glue in each slot. Also, spread a bead of glue over the entire surface of the joint. Reinsert the biscuits and assemble workpieces.

nClamp workpieces together until the glue sets up.

If the workpieces are of the same thickness, clamp them securely to a workbench with the short sides up. Set the fence angle at 45°. Place the biscuit joiner on the workpiece with the adjustable fence resting on the short side of the workpiece and the base or vertical fence against the mitered edge of the workpiece. Follow steps above to cut required slots.

NOTE: Before cutting slots, make sure the blade will not cut through the workpiece and that both the vertical and horizontal fences are pressed flat against the mitered edge and face of the workpiece.

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.
