The most popular saw is a 12 inch compound miter saw like the Makita LS1221 (about $350 or so). If the molding is not terribly large, a 10 inch dual sliding compound miter saw will do the job well (example Makita LS1016L, about $550 - 600). The dual sliding saws are really designed for cutting crown molding.
you could build a miter box that holds the moulding at the same angle as it is mounted between the wall and ceiling. Lay the moulding against the front and back of the box and cut across the face at a 45 degree when viewed above straight down. If the moulding is setting as it would be installed it should fit
You can use anything you want, but, crown moulding has 45deg flats on the back so they sit even between the ceiling and wall. If you use anything but crown, you would have to make marks on the wall or ceiling so it runs level around the room. With crown moulding, it is better to cope the pieces instead of the 45 deg cut on ends.
A compound mitre saw can cut angles in both directions and ALSO tilt the blade to cut compound angles, This is important in cutting things like crown moulding.
To properly install crown molding, you should cut the angles at 45 degrees.
First of all, pull up different crown moulding profiles, baseboard as well as dental moulding profiles from a trim molding supplier online. Most websites provide PDF files of their moulding profiles that are to scale. Sketch a straight line across the top of a piece of graph paper. Sketch a line 90 degrees to the last line in order to represent the wall of the graph paper. Cut out your moulding profiles that you downloaded from the internet. Position the various moulding profiles on the graph paper with the aim to make customized crown moulding profiles, which will give you an idea of how the built-up crown moulding profiles will appear once it has been installed on the wall. Pick up a sample of each one of the moulding profiles that you chose to use from the trim supplier. Secure them firmly together with the help of glue and nails in a way that you would want to assemble them onto the wall. Once it has dried thoroughly, place it up against the wall to confirm whether or not you like the moulding profiles. Install the built-up crown moulding profile one piece at a time. Make use of the sample mock up of the moulding profile as a reference to demarcate a line where it will start on the wall. From the ceiling, measure the distance all the way to the bottom of the built-up crown moulding profiles. Transfer this distance to each end of one wall and mark the location there with the help of a pencil or marker. Use a chalk line to draw a straight chalk line along the wall, which will serve as a reference line to place the first piece of crown moulding profiles. Repeat the process for the remaining walls.
When cutting crown molding, two angles are typically used: the miter angle and the bevel angle. The miter angle is the angle at which the molding is cut horizontally, while the bevel angle is the angle at which the molding is cut vertically. These angles will vary depending on the type of crown molding and the corners being joined. It is important to measure and cut accurately to ensure a proper fit.
If you are doing a 90 degree corner, the miter angles with each be 45 degrees at the cut. If you are doing a corner that is not square - you are going to need a protractor or another device to measure the angle. Square corner or not, the sum of the miter angles will equal the total angle of the corner.
To add moulding to cabinets for a decorative look, measure and cut the moulding to fit the cabinet doors and sides. Sand the edges for a smooth finish. Attach the moulding using wood glue and finish with nails or screws for extra support. Paint or stain the moulding to match the cabinets for a cohesive look.
To create picture frame moulding for your project, you will need to measure and cut wood to the desired dimensions, then use a router to create the decorative profile on the edges. Sand the moulding smooth and finish with paint or stain as desired. Install the moulding around the edges of your picture frame using nails or adhesive.
According to the site, below:"Crown - the portion of the diamond between its girdle and its table - the Crown angle in the well-cut diamond should be 33 to 35 degrees."There, you can read more about diamond cuts.
I'll assume you mean literally, as opposed to some metaphorical phrase like "glass ceiling", and that furthermore you know what a ceiling is and are just curious about the "gilded." Gilded means "covered with gold". In the case of a ceiling, it would be very thin gold foil applied to the ceiling. To add to your answer, you are correct but the term was mostly used with regard to ornate plaster moulding in the crown area and around central disks where gas lines passed through for lighting. The wooden crown moulding would be cut to lengths easy to handle. Each piece is then covered with mesh hemp or linen fabric that is very loose to prevent cracking and to allow easy removal from the mould. It is then covered in plaster of Paris and placed into the mould ( hence the term moulding) Afterward it would harden or "set up". Once set up, the moulding would be removed from the mould and then guilded with gold leaf.
To create picture frame moulding, you will need to measure and cut wood to the desired dimensions, miter the corners for a seamless fit, and attach the pieces together using glue and nails. Sand the moulding to smooth out any rough edges, and then paint or stain it to your preferred finish. Finally, attach the moulding to the edges of your picture frame using adhesive or nails.
