OPERATION

CUTTING CROWN MOLDING

Your compound miter saw does an excellent job of cutting crown molding. In general, compound miter saws do a better job of cutting crown molding than any other tool made.

In order to fit properly, crown molding must be compound mitered with extreme accuracy.

The two contact surfaces on a piece of crown molding that fit flat against the ceiling and the wall of a room are at angles that, when added together, equal exactly 90°. Most crown molding has a top rear angle (the section that fits flat against the ceiling) of 52° and a bottom rear angle (the section that fits flat against the wall) of 38°.

LAYING MOLDING FLAT ON THE MITER TABLE

See Figure 33.

To use this method for accurately cutting crown molding for a 90° inside or outside corner, lay the molding with its broad back surface flat on the miter table and against the fence.

When setting the bevel and miter angles for compound mi- ters, remember that the settings are interdependent; chang- ing one angle changes the other angle as well.

Keep in mind that the angles for crown moldings are very precise and difficult to set. Since it is very easy for these angles to shift, all settings should first be tested on scrap molding. Also most walls do not have angles of exactly 90°, therefore, you will need to fine tune your settings.

When cutting crown molding by this method the bevel angle should be set at 33.85°. The miter angle should be set at 31.6° either right or left, depending on the desired cut for the ap- plication. See the chart below for correct angle settings and correct positioning of crown molding on miter table.

The settings in the chart below can be used for cutting All Standard (U.S.) crown molding with 52° and 38° angles. The crown molding is placed flat on the miter table using the compound features of your miter saw.

MS1250LZ1 specifications

The RIDGID MS1250LZ1 is a state-of-the-art miter saw designed to meet the demands of professionals and DIY enthusiasts alike. With its robust construction and innovative features, this powerful tool is optimally engineered for precision cutting and versatility in various applications.

One of the standout features of the MS1250LZ1 is its 12-inch carbide-tipped blade, which provides outstanding cutting capacity. This generous blade size enables users to cut through larger materials with ease, making it ideal for framing, trimming, and even crosscuts. The saw’s powerful motor drives the blade at an impressive no-load speed, ensuring smooth and efficient cuts through hardwoods, softwoods, and composite materials.

The MS1250LZ1 incorporates advanced miter and bevel cutting capabilities. It offers an easy-to-adjust miter angle ranging from 0 to 52 degrees, allowing for accurate cuts in various directions. Additionally, the bevel capability can be adjusted up to 45 degrees to the left, providing more flexibility in creating complex cuts. This is particularly handy for crown molding, baseboards, and other intricate woodworking projects.

Safety is a significant consideration in the design of the RIDGID MS1250LZ1. It features a blade guard that provides optimal protection while allowing for a clear view of the cutting area. The electric brake ensures the blade stops quickly after use, reducing the risk of accidents. Furthermore, the saw is equipped with a horizontal handle that enhances control, reducing fatigue during prolonged use.

The tool comes with an integrated laser guide that illuminates the cutting line for enhanced accuracy. This technology fine-tunes the cutting process, ensuring precise results even in low-light conditions. The built-in dust collection system helps keep your workspace clean by capturing sawdust and debris, promoting a safer and more efficient working environment.

Constructed with durability in mind, the MS1250LZ1 features a solid, heavy-duty base for improved stability. This stability is key during critical cuts, reducing vibrations that could affect accuracy.

Overall, the RIDGID MS1250LZ1 is a reliable and efficient miter saw that combines power, precision, and user-friendly features. Whether you're tackling professional projects or home improvements, this miter saw stands out as an essential tool for achieving flawless, quality results.
