My Dad and his brother built the house that I grew up in (1948). I always thought my Dad was sort of a perfectionist, and he considered his brother a perfectionist, so I guess his brother was a super perfectionist. He told me that all the corners in that house were square. They were not professional carpenters but grew up poor, in a large family during the great depression, so they learned a lot of mechanical skills. They could build houses, pour concrete, and were good auto mechanics. If it was mechanical they could probably fix it.

Awesome instructions! I cant tell you how much time Ive wasted just staring at an angle cut, scratching my head, and trying to remember my highschool geometry. I now have the formula memorized. Every woodworker needs to memorize this useful tip!

Best explanation I’ve heard for cutting angles, I’m not as intimidated anymore, thanks!!!!

I learned more in less than 15 minutes than I did all of high school for math. Thanks so much!

Exceptionally clear and informative lesson. I was able to complete my baseboards like a pro! Thank you for sharing this!

Great job guys! One of the best, easiest videos out there! The trick is remembering that miter saws are set @ 90 degrees already. You have to deal with that 90 degrees when figuring an obtuse angle. These guys did a great job.

Need to pass along a quick story. 2 weeks ago I was replacing some counter top trip. I could not get the angle. Kept trial cutting and trial cutting. Finally, I got the angle. I hadn’t even looked at my miter saw to see what it was. I was so frustrated that I installed the trim and shut down for the day. I just remeasured the angle then used your formula for Obtuse angles and came up with a figure. Went to my miter saw and it was still set to the last angle I cut. It was set after trial and error at exactly what your formula calculated. Wish I’d see this earlier. This is a great tutorial. Thanks much!

Love your style of teaching brother, thank you for breaking it down 👍🏾

Great explanaition! I struggled with getting the right degrees and then how to take that to the saw and get it right. I'm very bad at math but this couldn't be more clear! Thanks a lot! I've been searching for a good video for a while now and this is the one i needed!

Nothing obtuse about this video, it is just great, absolutely exactly what I needed, plus the best accent on the web! Thanks!

Very well done Sir! It had been a long time since I did any trim/finish work and I completely forgot the formulas and your video was spot on. I appreciate you for taking the time to share this with us. Thank you!

I appreciate the shit outta this. Helped me trim out a obtuse bathroom with angles I’ve never had to deal with before. Great job explaining too.

Great video. Love the math lessons. We tend to eyeball everything in life, but leave out the fundamentals. Thanks for your lesson.

man awesome explanation! I've struggled with angles my whole life with my home projects. Thanks for the easy explanation. My wife is going to think I'm a genius for our upcoming projects. Thanks so much!

Beyond helpful to wrap up my bathroom project, house from 1890 it's literally different measurements every 6-8 inches everything is so settled and shifted over the years. Appreciate it 🙏🏻💯

For most of my life I've struggled with these cuts, not any more. Great job, easy to follow, thanks mate.

You did an excellent job explaining this.!

Chris - A great video and clearly explained tutorial. Great job. I have the same Husky Digital Angle Finder and wanted to point out a feature on this angle finder that simplifies your math calculations for obtuse angles. On your Husky angle finder, please note the two red buttons next to the digital readout. 0/On and REV. 0/On = zero calibration/turn unit on REV = show the reverse angle from 180 deg. After you take your first obtuse angle measurement (reference 4:40 in your vid) of 110.0 degrees, rather than do the math one of the two different ways you show, there is a third way. With the Husky Digital Angle Finder display reading 110 deg as in your video, press the REV button. This gives you the reverse angle which will read 70.0 on the digital read out. Simply divide 70.0 (the reverse angle) by 2 and you have the correct angle, 35 degrees, for your miter cut. Math simplified! FYI, I'm not affiliated with Husky of Home Depot in any way. I'm just an interested retired handyman around the house. I really enjoy your videos.

For once, youtube suggestion got it right, lol. I've watched countless baseboards how to videos. Your description on cutting inside corners is by far is the best. Thank you👌

I’ve always found cutting angles intimidating. You explained it so well! Going out to get the tool right now. Thanks!

This helped me SO MUCH! Thanks for the great explanation and examples.

Exceptional video. Finally , someone explains the how and why. Great Job! Thank you

Thanks for solving my miter issue mr. "sawdust" guy. Bought an old house. It is well made with lots of non-square angles. Watched you do stuff...now i can do it. Thanks.

The simplest explanation video I’ve ever seen for cutting angles on a miter saw.

Super-helpful video. I'd spent ages trying to work out a couple of obtuse angles for a picture rail and was pulling my hair out!, After using your calculations, I got it first hit. Thank you so much.

Thank you so much, this was very helpful for someone starting out with woodworking!

THANK YOU FOR THIS VIDEO! It saved me from an incredibly frustrating Saturday. If you ever come to Nashville, TN the drinks are on me.

I just watched your video explaining the speed square and now this one. I really enjoyed them. You made it quick and easy to learn how to use them properly. Determining angels and cutting them with my Miter Saw is no longer intimidating!

This was so helpful. Thank you for being so clear and demonstrating several times!!!!!!

Thank you for this explanation! This was exactly what I needed. You made this seem so easy...I don't feel so overwhelmed now. I went out and bought an angle finder. Now to put this into practice. Cheers!

I moved to small town where no one wants to work during the pandemic. I need all the baseboards and trim replaced. I now feel very comfortable to try it myself. Great video, thank you very much. And thank you for showing me how to practice before I start.

Excellent video! This is beyond helpful, I was cutting every degree until my pieces matched up it was a nightmare. All of the people who disliked the video must have a learning disability because this was both easy and informative.

you mean 180-110.....great video!

I’ve learned from this video. I’m glad I tuned in. Thank you.👍🏻

Thanks you for this video! It helped me a great deal after i installed a Engineered floor and needed to hide my expansion gaps with shoe molding.You made it very easy to understand and being from the Northeast the Lewzeanna accent was a bonus! My brother is a priest in Nawleans and I love visiting him! Thanx again I really appreciated it!

Best explanation I’ve seen yet. Straightforward, and to the point! Thank you!

I need to buy an angle finder now. Sure nice having fun with my new miter saw!

Thank you for explaining this soo well! Very helpful!

Thank you so much for this information, it helped me a lot. I've watched other videos but yours is so simple and not confusing at all. I'm doing crown molding in my kitchen tomorrow and you just made my life so much easier. I have quite a few obtuse angles with vaulted ceilings from 12' to 8' and visa-versa. I did my living room and dining room last week, and these angles drove me crazy. Thanks again and God Bless.

You rock! Thank you for the formulas at the beginning! I was thinking of it mathematically like that but didn’t know if what I come up with would work or not but makes complete sense when I see it written down! Thank you so much!

Thanks...I had trouble with this... great explanation

Thanks! Very clear, easy to follow instructions. I was struggling with my fireplace trim - outside corner 135 degree angle. I didn't have an angle finder so I put two rulers together with a wing nut then used an online protractor. Worked perfectly.

Thanks for the great video Chris! I’ve been doing it without the math for ages but your way is gonna save me a ton of time, have a great xmas fella and I’ll look forward to more videos👍

Man I was really struggling trying to cut baseboard trim for my kitchen. Found your video first and nailed it. The way you explain, and the pace, combined with the visual at every step totally made this click for me. Thanks man👍🏻 subbed!

I would really love to hear you say, “I tell you what...”

Excellent Excellent job explaining. Great step x step. One question that I have is that, when measuring for the length of a piece of baseboard or crown molding corner to corner or even from a door way trim to a inside corner... Do I measure just the exact length like I would anything else, or would I measure a little extra bc I’ll be cutting off the ends for the angles? I’m doing my baseboards for my dining room today, so I could really use the advice. Please and thanks. I have to first go and buy a digital angle measure guide. Hope their not too expensive? Thanks again. Merry Christmas and Happy Holidays to you and yours. I’m now a new subscriber after watching this video. 👍🏻

Thanks so much! I just finished wainscoting my winding staircase. I never would have figured out all the angles without your videos!

I had no idea cutting angles was so easy! I have a project I have been avoiding because of the angle cuts. Thanks for your help!

Does this guy do the voice for Cleveland from Family Guy?

Thank you so much for taking the time to make this video it was very helpful, great job!

Thank you for making this so simple to understand! The real pros and knowledgeable people always make anything they teach look easy!

Very helpful. I was going crazy trying to figure it out on my own. Thank you!

Great video and explanation! 🙌🏼 It saved me so much time and kept me from wasting a bunch of materials. Otherwise I'd would of used my typical cut and test method.

very helpful and easy!! thanks

Thanks for the help. In regards to the video itself, nice job on the math reveal - hiding the written math until we needed to see it.

Thank you so much for the prompt reply! Will be searching, keep on "teachin"!!!

Thanks so much for this video. Just came across it. I just ordered that angle finder on amazon. Gonna do some chair molding.

Wish I would of watched this before I did my cuts on my project today!!! This seems so easy and yet I was so confused and frustrated with the angles I just glued it together and called it good 😕

Thank you so much for your precious video showing how to find inside and outside angles and cut. Yes, it did help a lot.

By far the best explanation on cutting angles I’ve found on KZfaq!!! I’ve watched soo many different videos and you give the best explanation, with many different examples. I’m currently building a console style subwoofer box that has a bunch of angles and I’m struggling to figure out how to join the angles. Thank you for this video. You saved me a bunch of headaches!!!!!!!

Excellent video buddy thanks a lot for sharing your knowledge very well explained the best I've seen on KZfaq God bless you and yours brother

Thank you!! This is so easy to understand. I was really struggling with obtuse cuts.

Thanks man. I got that same angle finder and was still having trouble. Now I know I can just press the REV button on the tool and divide by two. So easy! Thank you.

Didn't view all comments sorry if someone else mentioned this. 5:40 into video it's not 180 divided by 110 equals 70 instead it's 180 minus 110 equals 70. Thank you for the video, it's very helpful and well done.

Your a trim carpenter. I know your traits when cutting these boards. Plus, Chances are very slim the guy who is not a carpenter would know these formulas. I’m a carpenter but chose a little different way to find my angles. I precut my angles in trim pieces and because the angles on a wall would often be a degree or two off because of Sheetrock mud or due to the rock not being nailed off correctly. Great video and refreshed the math for me. Thanks!! Also, you have to be in south Louisiana or at least south of Shreveport. I know the slight accent. Are you Cajun? I’m from northeast Texas about 10-15 minutes from Louisiana. Thanks again, friend!!

Understood, but correction should be 180 minus 110 =70

Great stuff! A clear and simple explanation that clarifies the entire process. This goes to show that the BEST teachers aren't the ones with all the fancy academic degrees and certifications, but people who actually practice what they're trying to teach. As the saying goes: "Those who can DO, Do. Those who can't DO, Teach.

Had no idea this was how you do it...can't wait to have at it with my crown molding in my newly constructed recessed kitchen light box...

this is a good video but I think the information for an acute angle is a little misleading. Please forgive me if I missed it in your video, but it seems that your information is stating that any acute angle is simply divided by 2 and that is the cut you make but that is not correct. if you have an 85 degree inside corner, and you divide 85 by 2, you would get 42.5 and two 42.5 cuts would not make that corner. you need the complimentary angle to make that cut. so you need to use your same math, 180-85=95 and 95/2=47.5. so you need to make the cut at 47.5 to get the 85 degree corner. Did I miss that point in your video? if so my apologies

Great video! Way too many ads lol

Awesome video! Thank you for this tutorial! Makes since now! Thank you so much!

Thank you! I've put off finishing the trim on one of our walls because I couldn't find good directions on cutting inside obtuse angle trim. Yours were clear and detailed! Now I can finish our wainscoting and baseboards!

Great job! Love the digital angel finder, i will have to get one

Thanks! I needed this for framing in a 140 degree alcove in my basement!

Thank you. This was clear and very helpful. Practice was a good thing. I needed to lock down odd degrees on the saw so they don't move. I hope you do more videos.

I almost NEVER comment on videos. This explanation was fantastic! Straight to the point. Loved it!

Почему это мне никто не обьяснил намного раньше?????Браво Автору!!!!

Thanks Bud. I ordered the digital bevel gauge for $26.00 with free delivery. My old bevel gauge served me well and deserves retirement.

Thanks a ton!!! I'm new at DIY things and this will help me tremendously with finishing our staircase project.

Thank you so much ! I have stumbled through those corners a few times, I get the obtuse math now

Jesus you’re the only guy explaining this the right way

Great explanation of how to figure out the formula of how to cut obtuse and acute angles. I can’t wait to try this out. Subbed!

Thank you for correcting one of the many daddy issues I currently struggle with

Man you explained this perfectly now I'm knocking my baseboards out like a pro

The waterboy just educated me on miter cutting crown molding...o.O

This video was so helpful. You really simplified it, thank you!

This has to be one of the best ways to get a strong cut. Thx

The best explanation I've seen yet. Thanks Man!!

Hey great 👍 video explanations man. Yours are the 1st examples I've seen where you've already cut & put together examples before you begin. That helps in anyone's explanation of what point they're trying to get across. I'll def be sharing your vids too 😀

It’s starting to make sense Thanks so much from a beginner woodworker in Jamaica

I HAVE AN OCTOGON ENTRYWAY AND I JUST FIGURED OUT A regular octagon, each inside angle is 135°. After watching your video Thanks for the easy lesson

The last part of my patio fence has an angled handrail cut like this. Exactly the video i needed to see. Super clear and easy to understand. Thanks mate.

Yea man I tell ya I know a crawfish eating, head twisting and sucking creole when I hear em. 100% Cajun! Damn good video man! May the next beer cooler of crawfish be on me if we ever meet! You helped me align in on the miters. I thought it was me the whole time and according to your tutorial, it's the damn angles that's making my cuts "off" . I want to add in too... Be sure you are using a good blade and not the cheap ones. The cheap ones tend to have a bevel that can take about a 16th off the cut and you end up loose and instead of a 45 you have a 44. So what I do is calc the angle and subtract literally 1/16th off and it tightens the joint. You just make it look easy as pie but as usual, I have to over-complicate it because I always end up with the crap end of the stick of sorcery and always have to account for differnt stuff even when it's not supposed to be LOL. great video sir!

awesome job. thanks for the tip.

Hey Chris. Thanks for the very clear video. I have a more complex problem though. How do I go about measuring/cutting where THREE moulding pieces need to meet up? (I need to put trim where the walls meet as well to hide the raw edge of wood panelling. I'm stumped.

Hi Sawdust and Wood, Presumably if I don't have the height clearance on my mitre saw to stand the moulding upright, I have to adjust the bevel angle for an angled bevel cut laying the moulding flat, right?

Thank you very much for a very informative, clearly explained tutorial on determining correct mitre angles...We'll all save a fortune on two pack :)

Great job explaining everything thank you

This video is the best explained and demonstrated on the issue of cutting angles! I am so grateful to have found this, it has helped tremendously! Thank you!!!

GREAT Video. Best of the best on explaining the angles and how to cut them. Thank YOU.
