Hey what's up everyone this is JDMPlaya (from HS of course)

I want to do crown moulding starting in my living room.. This will be my first time messing with moulding. Is this difficult? My understanding I will put the corner mouldings up first then measure between them. Then follow with a 90 degree cut.. Is this a lot harder then it looks?

Let me know if you know of any good DIY guides on the net!

Crown moulding can be a pain. What do you want to do in the corner? Squares? Corner pieces? Or is it going to be a straight 90 in? That is the hardest to do, as you have to actually cope the moulding (Something I SUCK at doing)...

most people do 45's on each piece.

its a pain, because you need to factor the thickness of the adjacent piece in your cut, so that the inside of your cut is the short part, and the outside of the cut is the thick part on the 45 plus the width of the adjacent piece.

huge pain.

and frankly, from what i've seen, crown molding is entirely played out now, and only REAL molding from like the 1800's actually increases a home's value

Yeah my house had cheap crown moulding.. I like a clean ceiling crease better... Thats what I am converting my house to...

Crown Moulding or more specifically coping in general is not that difficult in and of itself. All it takes is practice. If you want a little trick try back cutting the piece you are trying to cope in order to gett rid of excess material then go back with coping say. The hardest part about CM is the fact that your corners, walls and ceiling all dictate what the final project will look like. I absolutely hate CM for the simple fact that nothing is rarely straight. If it were me I would look into a chair rail around the room as opposed to CM.

Cutting crown molding @ a 45 degree angle is not correct, it will leave a gapping hole (over an inch) on the top (where it meets the ceiling).

The link above is a pretty good starting how-to. Each installation is different due to corners not being a true 90 degree angle.

My question to you is what is your proficiency level with trim work - is this your first trim work project? If so, I highly suggest holding off, or go the easy route with corner blocks.

Well thats new to me ?? Coming from someone who has ran thousands of feet of Crown molding. If your ending up with an inch gap, I dont think your holding the molding right in the saw. Or you have a 22 1/2 degree wall. One inch is alot!

I think its very easy, cutting the crown molding is just in reverse of installation. Just picture the crown molding on the ceiling the way it is installed. Then take it to the saw and flip it upside down , sitting it in the saw the way you would in the ceiling, flushing the 2 flats sides on the gates of the saw. Remember that when your cutting crown, it is the opposite of installation. If you need a 45 degree angle on the left side of the piece of crown. Flip it upside down in the saw and cut the right side. If I am making 2 pieces of crown or more , I nail them together before I put them up on the wall. Making the miter completely tight and no gaps. I say buy a piece of white pine cheap mill crown and practice cutting.

cutting at a 45 assumes that the wall was perfect in relation to the intersecting wall and the ceiling. Anyone in construction knows how impossible that is. Each corner is different and should be coped to make sure the joint is as tight as possible. Start at the corner and cut a 22.5 ovelap (nerf joint here) where ever possible where whole pieces intersect.
