Miters on Crown Molding, Etc...


Hey all:
New to the group, So I introduce myself.
Have a pretty old Late 1800's house. I want to install some crown molding in the den, but the walls are very uneven and ceiling is not very plumb as well.
Should I break up the crown with opp 45 degree cuts, every few feet so I can get it to fit better, or just force a whole length of crown in (about 12'). Also does anyone have a nitre index table for 45 degree crowns.
Need about 80 to 98 degrees as far as I can tell. Every corner is different, and as I could fudge things a bit I would like it to come out as close as possible.
Before I get shunned, I know I could google this, but thought I would ask the experts first.
TIA & best,
Freddie

would do it in solid lengths. Get three or so pieces of wood from the floor to the bottom of the crown to wedge it in . small gaps at the ceiling will not show if worst comes to worst .
Cope all inside corners that will solve the angle problem there and on the outside corners cut them a degee or so over 45 and caulk the inside of the corners if required..............

Hi Freddie,
I am working on some crown in our family room with cathederal ceiling & wierd angles. I found Wayne Drake's book at:
http://www.compoundmiter.com /
very useful.
It might be worth a glance for your situation.

it's a good thing you ceiling isn't plumb... : )
I'd probably hold the crown down from the ceiling a bit and run the pieces as long as possible, fairing out the wall as necessary to make the junction look right

One way to go, is to use full-length mouldings which, when used together, build up to a crown. The smaller cross-sections conform easier to irregular walls. Some of the smaller composite mouldings like the coves are very flexible. Most of the crown mouldings for sale are copies of the old-style built-up stuff from yesteryear.
YMMV

Thanks for the quick answers. I reckon I will go with long pieces, as has been so thoughtfully suggested. Found a good miter table on the De Walt site:

And also a nifty crown miter calculator here:

Ahh the power of the net...
Thanks for the help gang!
