How do you cut wood for corners and get it to fit together?

Question

We have crown molding to put up, but can't get the inside corners to come out right.

Answer 1

To expand on maintenancemark's good answer.  

On one end cut the crown square and long enough to go to the wall, and then the other one will be just like a regular inside corner.  Then, get a pencil and mark a line right on the front leading edge so that you can see where you need to cut. Then with a coping saw cut at an angle back in the opposite direction of your original cut and follow the line with the coping saw.  The good thing is that if your walls are out of square the crown the cope is going to help compensate and make it look better.

Answer 2

JBG IS RIGHT.  HAVING THE RIGHT TOOLS MAKES ALL THE DIFFERENCE IN THE WORLD.

Answer 3

for inside corners... first put up one length 1'st without any cuts' (just square ends  and the correct length to fit) ... Then ,for the next run/leg.. using a miter box cut a 45' angle (then the cool and neat  trick is to use a coping saw to back/cut the miter) this is old school and nobody takes the time and effort to do this...the kids today just match up a couple of 45's (and there're never tight) then they just fill the gap with caulk.......go online  to Handyman or This Old House and search the perfect miter...or using a coping saw...

Answer 4

You need a miter saw, they make angle cuts, you can get a manual one at most hardware stores for about $10.00-$13.00.

Answer 5

You will mitre both pieces, but not necessarily vertically.  It depends on outside or inside mitre, etc.  I've attached this webpage for you.
