Crown molding
 

So I am about to start my first crown molding project. Any suggestions appreciated.

Thanks

The bigger the molding the bigger the nightmare. So how big is the molding and what saw do you have to cut it with?

I haven't decided yet but I think I will go with something small. Probably like 2 - 3". I have a compound mitre saw that I am fairly comfortable with. I tried reading about molding but there is a lot of conflicting info out there.

The table of the saw is the ceiling and build a jig that will hold the molding on the correct angle against the fence. Just build a box like the old handsaw jig, but to fit the molding. Bosch makes a neet angle finder. Drywalled corners are never square.

Once you have that you just have to remmember that everything is upside down and backwards.
If you go with a molding to big to stand up like that you have to set both angles on the saw and that gets really tough.

Great thanks Neal.

One question Neal. Say I use the angle finder and it shows the wall to be at 87 degrees instead of 90. How would I then cut the molding to fit? Also should I cope or not?

I never cope crown but could on the inside corners. for 87 degrees, you cut both sides to 43.5. Just divide in half. The bosch square will give you the answer. It would would read 43.5.
Learning how to cut the stuff is just the start, accurate measurement are just as important. And then placement on the wall is critical, any little bit up or down really screws the angle up.

One last question (maybe)
 

Great info thanks Neal. Is coping the inside corners easier for someone like me?

I never found it easier to cope, but I don't do alot of this stuff. Just try a few samples and see what your comfortable with.

I used a thermal label maker and put a label on my miter saw reminding me of inside and outside corner "good" side so I have 1 less thing to remember in my head. Helps me out a lot.
