installing crown molding

Crown moulding is a bit trickier than you would think. You have to make the 45 degree cut while holding the moulding at the same angle it would be on the wall, as oppose to laying it flat on the saw base or standing it up against the saw fence. So put the "top" ceiling edge of the moulding on the base, and then lean the "bottom" or wall edge against the fence of the saw so that the moulding is at the same angle it would be between the wall and ceiling. If you have a triangle of wood you can put under it to stabilize it, all the better. Then you just make a straight miter cut of 45 degrees(as opposed to compound). Gosh, this would be so much easier if I could just upload a picture with my reply, can't wait to get to 500. Anyway, hope this helps out, if you didn't already get it on your own. Good Luck.

One thing to remember, not every angle is 45 degrees. It is important to measure each angle, then cut it. In order for the angles to be a perfect 45 degree angle, the builder must make everything perfectly square. The sheetrock man must make sure everything is perfectly square. If you are redoing an older home, you can forget a perfectly square angle because of the settling of the home. I would measure every angle, you will see what I mean.
