OPERATION

MITER JOINTS

See Figures 18 - 21.

There are two types of miter joints that can be made using biscuits: flat miters and edge miters. Flat miters are used when making picture frames. Edge miters are used when making boxes or things where you don’t want to show the end grain of the wood.

MAKING FLAT MITER JOINTS

See Figure 18.

nUnplug the biscuit joiner.

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

nUsing a combination square, draw a line through the cen- ter of each joint perpendicular to the mitered edges.

nSet the fence angle at 90°, set the fence height at the desired dimension on the scale, select the correct depth of cut setting for the biscuit size you plan to use, and clamp the workpiece securely.

nAlign the indicator mark on the fence with the centerline on 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 the 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 as- semble the workpieces.

nClamp the workpieces together until the glue sets up.

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.
