Can anyone give me tips on measuring and cutting 45-degree angles for installing quarter round?

Answer 1

any type of miter box will work, the larger ones make it easier but the cheaper ones work too......when measuring, if turning a corner, measure the wall length, one is an inside corner the other end is the outside corner...

but the base on the inside corner and measure to the longest part of the outside corner.....cut a 45 deg with the long point on the inside of the qt round for the inside corner......cut a 45 deg on the the outside for the outside corner, but the measurement is to the short point not the long point......

its hard to explain but if i were u i would take 2- 6" pieces and practice with them......once u get it right once u will have it down pat

Answer 2

I use a cutoff saw. A cheap one costs about $100. My angles are a little sloppy, but they're acceptable for my purpose. Quarter rounds are small--if you have a big gap (because of an imprecise 45-degree cut), you can fill it in with wood putty; after painting, no one will notice. I have not had to do that (I also cut door/window trim, and the imprecision showed worse, but generally it's within the acceptable range).

If you don't want to buy (rent, borrow) a cutoff saw, get a mitre box. They're cheap and will probably do the trick. They have guides for a hand saw, to keep it sawing at the proper angle.

Check and double-check before you cut. Hold up the piece to the window and make sure the angle is measured from the correct flat side of the q.r. After messing up a couple of pieces, I always marked which flat side would have the straight cut. (I'm sorry, I don't know how to word this properly. If you mess one up, it'll probably make a lot more sense! Just cut the long pieces first so you can still use the scrap!)

Also, cut your long pieces first--that way, if you mess it up, you can use that piece for a shorter piece. Mess up a short piece and you throw it away. Thank goodness q.r.'s are cheap! Cut the long pieces [for each window, not for the whole jog--do one window at a time], then install them. Then cut the short pieces and at least lay them on the windowsill the same day, so you won't forget where you are. Make sure you stop at points that won't confuse you if you don't get back to it for a week. Don't assume you'll remember. Of course, you may not be a dense as I am, so that may not be a problem for you!

As for measuring, measure from inside corner to inside corner. Cut the q.r. Go fit it to the window. If it's a little long, will it fit perfectly on the other side of the window? If not, cut off a tiny bit until it fits. Do the same to the other side. Then do the top and bottom.

On an outside corner, mark the backside of the cut as the point where the cut starts. Do the same for the other side. If it is a 45% corner, then each side is cut at 22 1/2% from that mark. If it is a 90% angle, each side is cut at 45% angle from that mark.

Answer 4

You're in luck. A simple miter box is the answer. You can probably pick a basic plastic one up, with a wood saw at Home Depot for $10-$15. They're cheap, easy to use and work very well.

Answer 5

Use a miter box. You can get one at any hardware store relatively cheaply.
