Using Compound Miter Saw
 
Just bought a new compound miter saw. I am having a tough time cutting the correct angles.

Can anyone help me? I do much better with good instructional video.

Anybody out there?

What kind of angles are you trying to cut?

Are you having a problem setting saw to the correct angle or are you trying to figure out what angles to use for whatever project you're doing?

I am having both issues. I can not seem to get the corner cuts both inside right and left to fit.

There is always the possibility that the saw's settings could be off. Check them with a speed quare and test cuts...

Are you cutting it flat, or are you cutting it in position (upside down and backwards). Cutting in position is easiest for me. The fence is like the wall, the base is like the ceiling. You lay the crown upside down against the fence (thin edge up, with the profile facing you) There will be a void behind the crown as it sits on your miter saw. Crown stops are a nice accessory that help hold the crown in a consistant position. For a 90 degree corner, just cut a 45 on it while holding it in postion.

Practice with small scraps until you figure out what you're doing. Cutting crown is a little puzzling at first. Do an internet search if you don't have a how-to book on it. There's plenty of web sites that explain it in pictures if that's what it takes.

Going from memory...which isn't always correct, the numbers you need for cutting crown laying it flat on the miter saw are 31.6 on the table and 35.3 on the arm. This works for 45 degree crown moldings. If your corners are out you will need to adjust the angles accordingly. Crown can be a slow process, but that's okay, take your time and it can look great in any part of the house.

I usually make a set of inside and a set of outside corners, go fit them in every corner to start and make a light pencil mark on the wall and ceiling as to it's best fitted position. Now you can measure everything up and cut away.

Look in the instruction manuel, the proper angles for typical 52 degree crown will be referenced on the saw some how, either with a built in detent or an arrow or tick mark on the scales. Many manuels also have a chart showing proper settings for other spring angles. the most common being 45 degrees. If not search on the internet, several sites have charts available that you can print.

Your angles are most likely incorrect and/or you're not positioning the crown correctly on the wall. This is where learning to use a coping saw will make inside corners easier and look better. The angles for cutting crown flat on the saw are 33.9 for the bevel and set the miter angle at 31.6. Many miter saws have presets or markings for these angles. If you don't have them, set as close as possible. Also, on many saws you can only set the bevel angle by tilting the head to one side, so depending on which angle you're cutting you may be setting the top or bottom edge against the fence.

Check these out and the other links on this site. Good luck.
