Best way to cut crown molding?


Hi-
I just spent a ton of time installing new quarter round throughout our entire first floor. Thankfully it is painted white so I had a little wiggle room with corner gaps.

I am planning on installing white painted crown molding as well but one of the biggest issues I had with the floor trim is that stuff just isn't square a lot of times--and I had to spend a lot of time carefully filling corner gaps or gently shaving parts to get a nice fit.

I want the molding to fit as best as possible and don't want to be monkeying around filling gaps if I don't need to. If I use a coping saw instead of my mitre saw will this help resolve a lot of those issues?

Thanks, sl

1. Get yourself a nice compound mitre saw
2. Get a coping saw
3. Get some scrap crown and start playing around with it
4. Get a good protractor (digital are easier to read)

Re: Best way to cut crown molding?


This is what I use when installing trim to find out what the angle really is.
It not only tells you the angle but tells you what angle to cut when it's a double cut without having to do the math.

This is what I use when cutting crown since I so seldom do it it made it super simple.

Flat on a good sliding compound saw with proper spring angles figured in. If you have to make adjustments, it isn't too bad.

Re: Best way to cut crown molding?


The best way to cut crown molding is to not cut it at all. And by that I mean, look at using corner blocks. That way, you will only have to do butt joints.

Other than that, take a look at Post #2, #3 and #4, read them thoroughly, practice them multiple times, join a twelve step program, seek a higher powered sliding compound miter saw.

And hope that you have 90* corners in every directions.

Re: Best way to cut crown molding?


@ktownskier , last crown job was spec'd with corner blocks on inside corners. I only had to cut 2 outside corners, and the rest was candy. I had to make the corner blocks, but setting up a production line made it easy.

Re: Best way to cut crown molding?


I have put in crown molding in all my homes. A very simple and easy way to add value and style to my home.

I have done it with corner blocks and the traditional way. I have hid speaker wire behind it, but never 120v.

Wood, foam, fiberglass, all different types of materials and all different types of styles. It is so much fun seeing the results. I have done it in friends houses and they love it as well. Every time I do it, I always learn some thing new, see a new trick, and find a fun way to add value.

Molding may see expensive, but, you don't need much to add major value. Try adding picture frame molding to your walls, paint the molding bright white and the interior a slightly different sheen or shade and you will be amazed at what you have accomplished.

My new home is posing a bit of a problem though. The ceiling is pitched from the center line to the outside walls. (It is a manufactured house. So, I am trying to decide how I want to deal with the side walls. Do I use a corner block or do I attempt a truly compound miter? Hmmm, interesting options, eh?

Can't tell from the pics, but do the arms on that thing rotate the other way to allow measuring outside corners?

@huesmann , it does both inside and outside corners. It looks gosh darn interesting. (Gotta watch my language in case the big guy is watching... )

Re: Best way to cut crown molding?


Thanks everyone. I had a digital protractor but I think I am going to get that Starrett model. I probably should have spent another $100-$200 and purchased a better saw, but I ended up with the Ryobi. I think I can get the job done with it but it has a few quirks that I have noticed after making countless cuts.

I just need to get some molding and practice around the house. It was easy being able to work on the floor for the quarter round but I think this is going to be a completely different game. We have some very long sections and I think my wife is going to have to help me hold stuff this time around!

Do people generally not put molding in the master bathroom? I would love to add it to there but my concerns is wood as it approaches the shower area. I was planning on purchasing real wood instead of MDF for that area but I know they *may* also have some plastic types?

Re: Best way to cut crown molding?


IMO, tall crown molding does not have much of a place in a home with 8' or less ceilings. The last one we did (with the corner blocks) was 9' ceilings and it looked great with the height. E-V-E-R-Y room. Master bedroom, bathrooms, half baths, hallways, kitchen, dining room. The entire house with the exception of non walk in closets.
