I have a little tool that measures the angles for me.

http://www.menards.com/main/tools-hardwa...6019-c-9149.htm

That helps with finding out the primary angle, but then you need to use your miter saw to cut that angle while holding the crown molding upside down and at an angle that holds the inside top and bottom edges flush with the base of the saw and the fence...

YouTube videos are helpful. If they start talking about 30-something % angles, it gets confusing, find a different video.

Don't they have cheater corners so that you don't have to really get the angles right?

Crown molding is a B___ until you get into a routine. There are lots of good tutorials but here is a couple of things that are worth considering.

-Get an angle finder that shows the angle and the angle/2. Yes, it's simple math but anything that reduces the chance of error helps once you are deep into it.

Take the time to build a seperate jig for both the left and right cuts at the table saw. You can buy them but they are easy to make from left over scraps.

My alogies for the big picture.

I guess I'm not seeing why the separate jig is necessary. Can someone tell me how I'm being stupid here?

Loc: It's all about the location.
The jig is for repeatability, Ken. Without the stop, it's difficult to hold the moulding in exactly the same place each time you cut a new piece which throws off your angles. It's also easy to do other corners besides the standard 90 degree using this type of jig. Where Andrew has his stop set at the bottom of the jig, I have mine screwed to the fence and push the moulding up to it(I don't use no stinking clamps on mine). Basically you're removing considerable math using a jig like this because you're only using the swivel on your mitre saw vs the compound angle style...you're actually cutting the trim as if it were already installed on the ceiling/wall.

So, to recap, Adrian and Murph are going to teach Ken how to put crown molding on Nick's subwoofer?
