With a table saw, tilt the blade for the bevel and turn the miter gauge to cut the miter.Family HandymanSetting Angles For Compound MethodBefore setting your saw for cutting compound angles, you need to know two things: the angle of the wall and the spring angle on the crown molding. (The spring is the angle between the molding and the wall or cabinet face.) Common crown molding spring angles are 38, 45 and 52 degrees. (See photo.)Once you’ve determined the wall angle and spring angles, set the bevel and miter angles on your saw.Note: Most compound miter saws have stops or mark settings for cutting standard crown molding.For standard 45-degree crown molding, set the bevel at 30 degrees and the miter at 35.3 degrees.Search online for a crown molding bevel/miter degree chart or calculator. A good resource is blocklayer.comFamily HandymanThe Non-Compound Method (The Easier Way)This refers to cutting the crown molding while resting the bottom against the fence and the top squarely against the table of your miter saw. Also known as the upside-down and backward method.Safe CuttingSince the molding rests on an angle against the table and fence of your miter saw, you’ll need stop blocks on each side of the blade to safely hold the piece from slipping while you’re cutting.One quick and easy option: Adhere stop blocks directly to the miter saw table using a few drops of hot glue or a couple of pieces of double-faced carpet tape.The safest option is to build an auxiliary fence and attach it directly to your miter saw fence. Once you’ve finished cutting all your crown molding, remove the auxiliary fence and convert it into a gluing jig.Another option is to purchase a crown molding cutting jig.Family HandymanSign Up For Our Newsletter Complete DIY projects like a pro!

Figuring the angle for crown molding is a relatively straightforward process once you have the appropriate tools and materials, so that the molding will fit properly. First, you will need a protractor, tape measure and a wide range of crown molding samples in a variety of angles and sizes to obtain the exact angle of the space where the molding will be installed. To accurately determine the angle:1. Measure the wall from corner to corner, creating a line of measurement.2. Place the protractor flat against the wall where the lines meet, with the pivot point on the corner, and record the angle marked on the protractor. 3. Hold the molding in a vertical position against the wall, so that the first groove of the molding is level, and read the angle marked on the molding. 4. If the angle on the wall and molding do not match, select a different piece of molding with a more suitable angle.Once you find the correct angle you can use a miter saw to make clean, accurate cuts in the molding, ensuring that it fits properly.What angle do you cut crown molding inside corners?When cutting crown molding inside corners, the easiest way to get a perfect cut is to use a miter saw set at a 45 degree angle. However, if your corner is slightly off from a true 45 degree angle, then you may need to adjust the angle of the saw accordingly.For example, if the corner is closer to a 47 degree angle, then you should set the miter saw to 47 degrees for the optimal cut. Before making any cuts, it is important to measure the angle of the corner to ensure the miter saw is set to the correct angle.It is also important to make sure the molding is firmly secured in the miter saw to prevent it from shifting as you make each cut. Additionally, some crown molding may require relieving on the back side of the joint in order to fit properly.A scrap piece of molding should be used to test any relieving before you make the actual cut into the piece you plan to use. With the right tools and techniques, cutting crown molding inside corners can be done relatively quickly and easily.What are the miter and bevel angles for crown molding?The miter and bevel angles for crown molding depend on the type of crown molding you are using. Generally, the miter angle is 38 degrees and the bevel angle is 33.5 degrees. If you are using a compound crown molding, the miter angle is 30 degrees and the bevel angle is 22.5 degrees.For bullnose molding, the miter angle is 30 degrees and the bevel angle is.

30 degrees. For interior or outside corner use, the miter angle is 45 degrees and the bevel angle is 31.7 degrees. If you are installing a cushion molding, the miter angle is 45 degrees and the bevel angle is 34.6 degrees.It is important to double check the manufacturer’s instructions as the miter and bevel angles might vary slightly depending on the size of the molding being used.How do you determine the angle of a cut?To determine the angle of a cut, you will need to first measure the angle you want to make with either a protractor or an angle finder tool. Depending on the type of material you are cutting, you will then need to set your power saw, like a miter saw, jigsaw, or circular saw, to the appropriate angle.If you are using a miter saw, you can use the miter scale on the saw itself to adjust the saw precisely. If you are using a jigsaw or circular saw, you will need to use a miter gauge or miter jig to adjust the cutting guide, which will help you to precisely set the angle you need to cut.Once the saw is set, check to make sure the saw blade is in the correct position and is tight and secure, before beginning to cut.What is the difference between 52 38 and 45 45 crown molding?The main difference between 52 38 and 45 45 crown molding is the angles. The 52 38 crown molding has a 52 degree angle and a 38 degree angle, while the 45 45 crown molding has two 45 degree angles. The profile of the 52 38 crown molding is steeper and more pronounced than the 45 45 crown molding, which has a more gradual and softer profile.The 52 38 crown molding is used to make sharp, bold statements, while the 45 45 crown molding is better for creating subtle curves. In addition, the 52 38 crown molding is typically used in rooms with higher ceilings since its steeper profile helps to create an illusion of a larger space, whereas the 45 45 crown molding is better suited for rooms with lower ceilings.What is Crown slope angle?Crown slope angle is a term used in the golf industry to describe the angle of the crown on a golf club head. Put simply, it is the angle from the base of the club head to the top of the club head, measured at the centre of the club face.Typically, the lower the angle of the crown the more forgiving the club head is to off-centre shots. This is because the club’s centre of gravity is lower and closer to the centre of the club face, meaning that Even slightly off-centre shots will retain some of their distance and accuracy.Crown slope angle is usually given in degrees and is usually around 8-10 degrees. Depending on the preference of the golfer, the degree of the angle will be adjusted accordingly to give the desired effect.Higher sloped angles create more of a draw-bias, low sloped angles create more of a fade-bias, and mid-range angles are suited to those who play without a bias.What is a miter cut vs bevel?A miter cut is when a single cut is made on a board at an angle. Generally, a miter saw is used to make this type of cut. The angle of the cut can be adjusted to accommodate various types of projects.This type of cut is often used to join two boards together at an angle, such as when creating the corners of a picture frame or molding.A bevel cut is similar to a miter cut, but instead of a single cut, two angled cuts are made to create a smooth 45-degree angle. A bevel cut is often used in cabinetry and trim work where an angle other than 90 degrees is desired.A bevel cut creates a smooth and polished line that evenly slopes from one board to the other. This type of cut is often used to join two boards together at an angle, such as when creating beveled edges on cabinets or trim.How do you cut crown molding less than 90 degrees?To cut crown molding less than 90 degrees, you will need to adjust either the saw or the crown itself so that the angel of the cut is less than a right angle. For an angle less than 90 degrees, you will need to miter the crown so that the inside corner formed between the two pieces is less than 90 degrees.To accomplish this, rest the shut off saw blade into one of the pieces of crown molding and then flip the crown over and move it against the fence of the saw in order to create a compound miter angle.Make several test cuts to ensure that you cut the angle correctly. You can then use a mitre saw guide or clamp to lock the two pieces of crown molding together so that when the saw is pulled across you are sure that the two pieces of crown meet together correctly.Once you have the correct cutting angle, make sure to always hold the crown molding firmly against the saw’s fence to reduce slippage and make the cut as accurate as possible.What is the F rule in angles?The “F” rule in angles is a geometric concept that states that the sum of the angles in any F-shaped figure are equal

Off the angle measurement from the protractor.Additionally, some protractors have a small arm that moves along the arc for measuring angles without having to draw any lines.Can you cut crown molding laying flat?Yes, you can cut crown molding laying flat but it is not the most precise method as it can be tricky to make sure the correct angle has been cut. The best approach is to use a miter saw or a coping saw.With the miter saw, you will make the cuts on the crown molding in an upright position so that the saw blade is parallel to the baseboard or wall. The saw should be adjusted to the desired angle and when making the cut, you will use the fence in order to guide the molding.For intricate inside and outside corners, a coping saw is the best tool to use as it will allow you to cut the molding in a variety of angles as well as to follow intricate patterns. The coping saw should be used to carefully cut along the patterns of the molding.When cutting the molding with either of the saws, it is important that you take your time in order to make precise cuts.What is flat crown molding?Flat crown molding is a type of trim used to add decorative detail to a wall or ceiling. This type of molding typically has an upper edge with a flatter, less angled border than other styles of moldings.This idea of a flat edge provides a more modern look that is generally used in contemporary interior design. One of the most common uses of flat crown molding is when joining two different wall surfaces or materials, like a wall and a ceiling, to create a seamless transition.The flatness of the molding also draws attention from the wall or ceiling, making it the focal point in the room. Flat crown molding is more affordable than other types of molding and can have a variety of styles, colors, and textures to choose from to match your aesthetic.Should crown molding be painted flat or semi-gloss?The finish of your crown molding can be a personal preference. You may choose flat paint, semi-gloss, or even high-gloss depending on the look you are trying to achieve. Generally, flat paint is best in low traffic areas, such as bedrooms and dining rooms.This paint finish has almost no shine and does not attract fingerprints when touched. Semi-gloss is best for areas with more traffic and a higher amount of wear and tear, such as hallways or childrens’ bedrooms, since it is easier to clean.Semi-gloss also provides a slight shine, which can help reflect light and make the room look more inviting and open. High-gloss paint is

Only one direction; this means that you have to line up either the top or the bottom edge of the molding on the fence to get the cut in the right direction, so you wind up flipping material a lot.Recently, I began using one of the new dual compound-miter saws. I admit I was skeptical at first that such a big lug of a saw would offer much of an advantage—unless I was dicing up huge pieces of lumber. But a dual compound-miter saw tilts in two directions, so you never have to flip the molding around. This is a big plus in a tight workspace. With the dual compound-miter saw, I always keep one edge against the fence and move the saw head to the left or right depending on whether I am cutting an inside or outside miter, left or right.With any compound-miter saw, you still need to find the correct miter and bevel settings. These settings change, depending on the spring angle of the crown molding you’re installing, and there’s no obvious correspondence between all the angles. I always keep handy a chart that lists the angle settings for the most common spring angles. For moldings that aren’t included on the chart, I use the Bosch Miterfinder (www.boschtools.com) to calculate the angle settings, or I simply make a reasoned guess and cut a couple of test pieces until I get the angles right. Then I write those numbers down so that I won’t forget them.Two tips to make the job go smoothlyBacking the crown means you never have to search for a stud. Framing lumber ripped to match the spring angle of the crown provides continuous nailing for the molding.A framing square and a scrap of crown determine the backer dimensions. After ripping the material on a tablesaw, the authoruses 3-in. screws to attach the backer to the framing.Installing crown to avoid double-coping. Starting off with a coped joint (fit to a temporary scrap of crown) ensures that the final piece of crown won’t have to be.This one comes out. Held up with a pair of drywall screws, a scrap of crown serves as a gauge to cope the first piece of crown molding.Coping inside cornersIt’s possible to assemble inside corners with a miter. However, even if the corner is perfectly square, most miter joints open after a few seasons of expansion and contraction. I prefer to cope crown molding. A coped joint is a marriage of opposites. On one side, the molding is cut square and butts tight to the wall. On the other side, the molding is “coped” to match the profile of its neighbor.A coped joint starts with a compound miter, the same as for an inside miter. The contoured edge along the face of this cut defines the profile to be coped. I mark the edge of this profile with the flat of a pencil lead so that it’s easier to see as I cut it with a coping saw. I always back-cut. Polygon Wall Horizontal Plane Angle Crown Molding Calculator. 12 Sided Polygon Crown Molding Angles. 12 Sided Polygon Crown Molding Angles with Rake Crown Molding Angles.

Gluecures. After securing the splint to the scarf joint, I smooth out the joint with sandpaper. Until they’re securely fastened in place, I make sure to handle these scarfed pieces with extra care; they can snap in two easily.Build a jig or buy a new saw?If you have to cut crown on a standard miter box, an auxiliary plywood fence with a stop applied to the front edge ensures that the molding is held at the correct angle in relation to the blade (photo below). Because the saw head on a dual compound saw tilts in two directions, you never have to flip the molding around to set up the correct cutting angle, which is a big advantage when working in tight or crowded quarters.Saggy ceilings and wavy walls demand special attentionIn old houses, where walls and ceilings aren’t smooth, I begin by mapping the planes with a level and string to find the low points on the ceiling. Long lengths of crown are surprisingly flexible and may move with gentle bumps and shallow dips. Most of the time, however, some remedy is required.One way to solve this problem is to scribe the top edge of the molding to the ceiling. When scribing, I don’t want to bite too deeply into the top edge, or the scribe will be easily visible. Generally, I don’t remove more than a third of the top reveal.Another fix is to skimcoat the wall or ceiling surface with plaster or joint compound to conceal gaps after the crown has been installed. In this case, I install the crown in line with the high spots. To float the mud, I make a screed from a short piece of mangled crown molding that has a notch in it that keys with the edge of the installed crown molding. This screed allows me to apply the mud to a depth that precisely covers the gap. I usually make the screed about 18 in. long, something that gives me a long, thin taper of mud that seamlessly feathers into the existing surface.Drawings courtesy of Dan Thornton; Photos by Andrew Kline and Tom O’BrienRELATED LINKSUpside Down and Backward Works Best for Crown MoldingCrown-Molding FundamentalsThe Secret to Coping Crown MoldingFrom Fine Homebuilding #152
