Abrasive Paper Installation

Disconnect machine from power source.

Proper attachment of the abrasive strips to the drums is important for achieving top performance from the sander.

See page 38 for a list of available abrasive strips with their respective grits and some tips on choosing the proper strip for a particular job. If using different size grits simultaneously, always place the coarser grit on the front drum.

Attach the abrasive paper as follows:

1.Open the hood by removing the handwheel and turning the two locking handles at the front counterclockwise.

2.Remove the socket head cap screw and locking wedge (Fig. 3) from both ends of the drum.

Note: If the wedge sticks, use a flat head screwdriver as leverage to free it.

3.Cut a length of the Ready-To-Cutabrasive strip (12' for the DDS-225, 16' 5" for the DDS-237). This will be enough to cover one drum.

Note: The taper on the remaining roll can later be used for the starting edge of your next strip.

4.Mark and cut a taper at the right end of the abrasive strip (Fig. 4). Because the tapered end should use all of the recess at the right side of the drum, its end must be trimmed back leaving an edge of about 1/2 inch, as shown. Now trim the left side of the abrasive paper in a similar manner (Fig. 5).

Note: An alternate method of tapering the ends of the abrasive strip is to place the removed sandpaper strip on top of the new strip and to use this as a template.

5.Begin at the right end of the drum and tuck the tapered right end of the abrasive roll into the recess (Fig. 3). Place the locking wedge into the recess and tighten firmly with the socket head cap screw.

6.Begin wrapping the strip around the drum, keeping it taut as you go. The tapered cut of the strip should follow the right edge of the drum. Continue to wrap the abrasive in a clockwise spiral fashion by rotating the drum with your left hand and guiding the strip with your right hand (Fig. 6). Successive windings of the strip should be flush with previous windings without any overlap.

DDS-225, DDS-237 specifications

The Powermatic DDS-237 and DDS-225 are two advanced drill presses that have been engineered for woodworkers who demand precision and versatility in their projects. These machines are part of Powermatic’s commitment to providing high-quality tools that cater to both professional and hobbyist woodworkers.

One of the main features of the DDS-237 is its robust construction. With a heavy-duty cast iron base and column, this drill press offers exceptional stability, reducing vibrations during operation which leads to accurate drilling. The DDS-225 follows suit, providing a durable design that ensures reliability even in the most challenging work environments.

The DDS-237 comes equipped with a powerful 1 HP motor, offering variable speed control ranging from 250 to 3000 RPM, allowing users to select the perfect speed for various materials. This feature is particularly advantageous for woodworkers who work with different species of wood or even metal and plastic. The DDS-225, on the other hand, features a slightly less powerful motor but maintains the same level of versatility with multiple speed settings.

Another significant aspect of these drill presses is their user-friendly interface and adjustments. Both models boast an easy-to-read digital depth gauge, enabling precise depth adjustments. This feature is crucial for applications requiring repetitive drilling depths, such as doweling or creating mortises.

Both models also incorporate innovative technologies aimed at enhancing user safety and convenience. The patented Quick-Release chuck system allows for rapid and easy tool changes without the need for additional tools, saving valuable time during setup and operation. Furthermore, the built-in work light illuminates the workspace, improving visibility during intricate drilling tasks.

Dust collection is also a fundamental aspect of both models, with integrated ports designed to minimize debris in the workspace, creating a healthier and cleaner working environment.

The Powermatic DDS-237 and DDS-225 are not just machines but essential tools that combine power, precision, and safety. Whether for professional use or serious woodworking enthusiasts, these drill presses are designed to meet the demands of any project with reliability and efficiency.
