Arcs and Circles

Large circular and arc-shaped stock can be shaped as described in Contour Edge Shaping on page 24. However, smaller sized stock requires the use of special shaping jigs similar to those shown in Figure 47.

With the entire fence assembly removed, carefully position the jig for desired depth-of-cut and securely clamp to the table.

It is important with the arc and circle shapes that the workpiece, prior to being shaped, must be roughly cut to the desired size and curve of the finished piece. Make sure that the jig curve matches exactly the workpiece curve. At all times keep the workpiece firmly in contact with the jig while the cutter is cutting the stock.

Never perform this type operation without a ring guard, safety collar or similar safety device over the cutterhead.

Enclosed Edge Shaping

An enclosed workpiece edge is shaped in the same manner as an outside contoured edge except that a starting pin is not required as shown in Figure 48.

Note: If the whole edge is to be shaped, the operator must use a pattern.

Position the workpiece on the table before starting the motor. The operator must do the entire shaping cut by pushing (feeding) the workpiece into the cutter(s).

Enclosed edge shaping is extremely dangerous. The operator must be aware at all times of the direction of feed. Never perform this type operation without a ring guard, safety collar or similar safety device over the cutterhead.

With a firm grip, ease the edge into the cutter(s) until stopped by the collar as shown in Figure 48.

Continue to push straight in while feeding and turning the workpiece at the same time until the cut is finished. Turn off the motor and do not remove workpiece until the cutters have completely stopped.

Never perform enclosed edge shaping if there is less than two inches of workpiece material all around the opening. Never perform enclosed edge shaping if the workpiece opening is smaller, in any direction, than twice the diameter of the cutter(s).

PM2700 specifications

The Powermatic PM2700 is a powerful and versatile bandsaw designed to meet the needs of both professional woodworkers and enthusiastic hobbyists. This robust machine is known for its exceptional cutting performance, advanced features, and user-friendly design.

One of the standout characteristics of the PM2700 is its impressive motor. Equipped with a 3 HP, 230-volt motor, the bandsaw delivers ample power, ensuring that users can tackle even the most challenging materials with ease. The motor operates smoothly and quietly, which enhances the overall working experience.

The PM2700 features a precision-engineered cast iron frame, which provides stability and reduces vibration during operation. The cast iron table is a generous 21 inches by 27 inches, supporting large workpieces while maintaining accuracy in cuts. Additionally, the table incorporates a high-quality, tilting feature that allows for bevel cuts, expanding the functionality of the bandsaw.

An essential aspect of any bandsaw is its cutting capacity, and the PM2700 excels in this area. It offers a resaw capacity of 12 inches, allowing woodworkers to easily slice through thick material. The machine also features an adjustable blade tensioning system that enables quick and precise adjustments to achieve optimal blade performance.

The PM2700 is equipped with an advanced blade tracking system, which helps in maintaining correct blade alignment during operations. This feature significantly reduces the risk of blade wandering, resulting in cleaner cuts and enhanced accuracy. The easy-to-use blade change system further simplifies maintenance, allowing users to switch blades with minimal effort.

Another notable technology integrated into the PM2700 is the built-in digital readout that provides real-time feedback on blade height adjustments. This digital feature ensures that woodworkers can make precise and repeatable cuts with confidence.

For safety, the bandsaw comes with several important features, including a blade guard and quick-release mechanism. Additionally, its robust construction minimizes the risk of injuries associated with vibrations and instability.

Overall, the Powermatic PM2700 is a top-of-the-line bandsaw that combines power, precision, and safety features, making it an excellent choice for anyone serious about woodworking. With its heavy-duty construction and user-friendly design, it promises to deliver outstanding results and durability for years to come.
