The Secret Formula for Making Perfect Miter Cuts When Less Than 90 Degrees

[@Jack37771488]

This is the best KZbin how to ive seen. This lady talks clearly and loudly enough to understand perfectly. No sound effects, no bells or whistles. Straight to the point by a master of her craft. Im your newest and biggest fan .

Truth is, that old chop saw prob works better than any new one.. So long as the blades sharp lol

[@steveiv9250]

Nothing wrong with that saw, Most of if not all brand name saws are great saws no matter the age, the only thing worth changing is the blade, whenever possible up grade your blade and using the correct blade makes a world of difference. ..love the Freud, Freud blades can make cheap no brand mitre saws decent enough for any homeowner who enjoys dabbling in home repairs.

[@IamFormaggio]

There's tear out because the base isnt flat. Could just add a piece of wood under the piece being cut. The base is wood because it doesnt rotate with the blade like newer saws do.

[@john-paulsilke893]

[@grrrl8521]

Leah, you're my hero! This is the second time you solve a problem for me. Those miters on baseboard for a staircase were driving me crazy. I came up with the formula 90 - x/2. "X" being the acute angle you want to divide. It works, but I wasn't really understanding the logic. I like your method and your explanation. Thank you. Solves a lot of second guessing myself.

[@conciencia21]

Leah, I have been in the industry for 20 years, i have worked with all kinds of great carpenters and builders yet none of them ever explained angles and miter cuts so thoroughly lie you have in this video. Many young apprentices tend to have a rough time understanding complementary angles, specially when it comes to exterior obtuse angles and interior acute angles. you have done a great job. Keep it up. It would be awesome if you could produce a compound miter cuts video.

[@rogergroover4971]

That’s great! I never understood why it was so difficult getting a correct cut when doing trim with a compound miter saw and now I do! Leah, your awesome! Thanks!

I've been woodworking for a long time & never knew that! Leah I wish you would've been there when I wasted all that wood going crazy wondering why my cuts were off! You're so awesome!

[@franciskisner920]

For those who do not have a digital angle gauge: Take a sheet of paper and lay it along one side of the wall so the corner of the paper just hits the inside of the corner of the wall. If the angle is acute, less than 90 degrees, there will be some extra paper against the wall on the other side of the angle. Fold that paper down so the paper just fits the angle and crease the fold. Now fold one side of your paper angle against the other side so the new angle starts at the corner and both sides are together. This paper angle shows how you need to mark your wood. You have just bisected an angle. For angles larger than 90, lay one piece of paper into the angle along one side and another piece along the other side so the corners meet at the corner of the room. Tape or glue them together and fold to make your half-angle. This also works for outside corners - Lay one piece against one side so it extends beyond the corner. Add another sheet from the other side and glue together. Fold and you will have the setting for an outside corner. No numbers have been mentioned. When I was replacing molding for a 3-window bay, no two angles were the same either at the base or the crown. Using this method all my trim fit exactly. Not a great carpenter but decent at geometry. Hope this helps.

[@suhailmadani4166]

This is helpful but sometimes the acute side is bigger and when not, the amount to fold usually isn't big so hard to do so but better than having no tools for sure!

[@amorgan5844]

Best explanation ive seen yet, great video!

[@morokeiboethia6749]

I bought that same Husky digital angle finder and after owning it, every construction worker of any form really should have one b/c it can find 2-D angles or 3-D angles where as a speed square can not determine 3D angles (like outside/inside corners of a wall) and a speed square can not get into a lot of places that the angle finder can. So many construction workers do not know how to determine angles and/or determine what angle to set the miter saw on to get that angle. A lot of guys think if you set miter saw at a certain angle, then you will get that angle on either the toe or heel after the cut but that will only happen on 45 degree setting. Its so simple but you cant tell someone who wants to appear like they know everything already even when its clear they dont have the foggiest clue what they're doing. Thank you for making this video b/c its probably the thing more construction workers struggle with is determining angles and determining what miter/bevel angle setting to achieve that angle. The non-digital angle finders don't really work in tandem with a miter saw b/c you gotta know what numerical angle the angle is. Trying to line miter saw blade with the manual angle finders takes too long and/or marking tricks to bisect an angle that you have scribed also takes too long. Having the number of the angle is what you need.

What if u measured the wall at 83 so by ur math I would have to set the miter at 48.5? Ur saw only went to 47.5?

[@rajmehtaphoto]

Using a Miter Saw Protractor (miter protractor) will take all the guess work out. This video definitely helped me understand though. Thanks! ... For anyone having trouble understanding this at first, just remember that in your head, you need to be starting out with the number 180 (straight line), not 90. If you start with 180 then minus the angle measured (85, in this video for example) you will get 95. Then, you take 95 and divide by 2 for your answer of 47.5. So, you cut 2 pieces at 47.5 and you are good to go!

[@Framer_Mike]

Blame the drywall finishers... I frame my walls square everytime.. :)

[@bethmurrow5626]

Yeah but it's something so important to learn what she just showed us. It will help tremendously in the future. You know its pretty rare to find a 90 angle. With settling of houses, lazy dry wall installers ect. Besides it's useful in so many other situations as well. Not just dry wall corners

[@maxfedor1]

Mike DEEZ yes and adding tape and mud in corners then makes it an acute angle. Just like adding corner bead to outside corner affects overall angle. So regardless if you frame it square after drywall taping it’s no longer a 90. And there’s a word for trim guys whose saws are stuck on 45. Hack. If you cope the inside corners you don’t have these problems

[@kevinotoole885]

Im a plasterer and I build my frames square, I board the square frame making the board square as it’s followed the frame. I then use 3mm thin coat angle bead which I then plaster with 3mm coat of plaster making it square. I’m not American so we plaster our walls not mud and tape or whatever you call it so I can’t talk for you guys I’m afraid.

[@tyronekim3506]

Good video. I think your explanation would have been more understandable if you had said "the finished miter cuts need to be 42.5° each (42.5° + 42.5° = 87°) therefore we need to cut way 47.5° each because the miter saw cuts the complementary angle, not the desired angle, except for 45° and 90° cuts." You did say that but at a round about way.

[@natethekid8072]

yes but 42.5 + 42.5 = 85, not 87.5. minor quibble but it may have tripped some up

[@montymont3327]

It is is the first time watching leaving confused

[@roberttill3787]

With a ninety degree angle the cut is fourty-five degrees each side, but as an oddly shaped angle is less than 90 the halving does not work. each piece of wood in a 90 degree mitre is 45 degrees, but you have to halve the actual measurement in an odd angle then take that from ninety, rather than just halving the measurement. If it is 85 degrees as demonstrated it is 90 degrees less forty two and a half degrees, which is forty seven and a half degrees as the cut. If you measure 85 degrees and half it then you get forty two and a half degrees, five degrees short. (eighty five and five = ninety).

[@meandyou917]

180-85= 95 95÷2= 47.5 47.5° is the angle

[@buttersstotch2014]

me andyou so if you were doing an abuse angle at say 94 degrees, how would that work out? 94/2= 47 90-47= 43 So you would set the saw at 43 ? And would you be setting that 43 in reference to numbers Leah wrote on the tape in her mitre saw?

Made it more complicated then it really is. If 85° (Acute angle) subtract from 180 and devide by 2 180- 85°= 95°÷2= 47.5° if 95° (obtuse angle) greater then 90 divide by 2 180° - 95°= 85 ÷ 2 = 42.5° 3rd grade math.

OMG this was so helpful, i was able to make perfect miter cuts for my quarter round for my baseboards after laying down my new luxury vinyl flooring.
