In this video we are talking about the times in woodworking and furniture making that we are able to take math and measurements out of the equation. Math and precise measurements can often be a difficult hurdle for new woodworkers, so we wanted to show how we often are able to complete certain tasks with very little math by using alternative techniques. Some of the topics we cover are order of operations, building trapezoidal boxes, router inlays, accurate dados, and incorporating angles into furniture.

as a mathematics teacher that has changed profession to woodworker/cabinet maker, this video hurts haha

I love this message. It fits right in line with how my brain works.

Were you two siamese twins at one point

Made me smile, and educated me in the same time. Thank you guys.

That woodpeckers flex though.

Why am I watching this? I have a math degree.

Haha, great advice!

To much math for a non math video lol.

How did you made that 3d demonstration to show different pieces š¤š¤

The only thing I get from this video is where not to order some woodcraft if I want something precise and cut clean š

There must have been two guys around the ice-age just like you, even their cousins didn’t know about them! What a time to be alive!

Love that drillbit technique… I’ll definitely be using it soon.

With some training in engineering, I used to strongly believe in the old adage, "measure twice, cut once"… Then I did some work with a carpenter with 30+ years experience, and so often he’d mark from actual pieces rather than measurements and sneak up on certain fits, measuring once and cutting 3-5 times… It really helped me bridge the gap between design and manufacture. We once built a deck together and I was getting all worked up about the length of the posts we were burying, the depth of the holes, setting things plumb. He taught me to throw all that out the window and just set string lines to get the posts well aligned and establish level with the the next set of beams, then move towards square with the next layer of joists, align the floorboards as well as possible, but only really worry about square when trimming the excess off the floorboards. It’s fine to aim to get every cut and joint as perfect as possible, but having the skill to make it work despite slight discrepancies in the measurements, that’s what really sets the craftsman apart.

According to my math changing 1 degree in a 90 cm leg would yield a difference of aprox 2,42 cm of the total width of the legs. It is not much but it is around a 3% change. If the legs were longer than that the difference would amplify much more! Thanks for the video.

I AM a Mathematician :'(

I definitely find the math intimidating. Aside from being a smidge afraid of fast-moving blades, I’m always worried I’ll measure or compute incorrectly.

exelent tricks guys, congratulations!!! i always learn newest thinks with your tutorials, keep teaching please

0:02 oh badass guys. I’m from Michigan and Utah. Digging the Jazz and Tiger’s hats.

Holy shit this is so freaking smart

Obviously a bit late, but just stumbled upon one of the best (informatively and comedic) videos Iāve seen from you guys yet. Haha! Great post and thank you for taking your time to do these videos! šš»

I’m a mathematician, or was, don’t work in maths anymore, so I don’t know if it counts. But a mathematician will agree that a relation between two objects is way more important than just a number. Only economists or engineers/statisticians who need to cater for economists will want absolute numbers.

Love you guys! Shaun, look at the camera when Chris talking, not all over the room like a bored dog. š

This is one of the best videos on your Channel! The editing is so creative and you guys are a lot of fun to watch!! Immensely inspiring š

As Pythagoras probably said "You can take the math out but not the geometry"

Fantastic video gentlemen! Seriously. š š š

Content. Visuals. Audio. Commentary. Humor.

you guys got me hooked

Trigonometry is a branch of geometry.

Physicist here with some defenses from the haters:

1) You are using math, you’re just minimizing the use of a ruler.

2) One of the first things I was taught in physics lab is "when you are using a ruler, you are actually taking two measurements, one lining up the zero, and one lining up the end" this does double the error. As you explained, a set table fence is 1 measurement, not two.

3) Trigonometry is a branch of geometry. I would say "relative dimensioning" is another branch of geometry – or just a subset of "euclidean geometry" – which is basically all the math you can do with a straight edge, and a compass – but each without markings. Relative dimensioning is a very old form math, because for a ruler to work, you need absolute dimensions, which needs a concept of zero, which was only invented once in human history in ~900CE – all carpentry and architecture before 900 – requires relative dimensioning.

4) Whenever I was doing numeric trigonometry – it is important that the sin/cos/tan be reported to 4 significant digits (e.g. sin(45) = .7071, not 0.71) (for length measurements of 2 significant digits). That’s why it wont work for wood working. Hobbyists work in 2 significant digits, and professionals work in 3. 4 significant digits is just not possible when working in wood, so the 4 sig fig that you need to do trig properly, is just physically impossible.

My personal hobby is to tell youtubers who say "it’s not math"/"this isn’t scientific", "yes it is". Keep up the good work.

but i like math………. like d(x^2)/dx = 2x im mean come on how could you not like that. Or if thats not your thing how about e^iĻ = -1. Damn that Euler knows whats up.

you guys rock

Loved the ending still laughing

EhKay, so… lol

Love y’all

LOVE the mid-century trapezoidal piece! Beautiful.

Great inlay setup. Thanks for all the info.

Thank you. I was just learning this on my own, particularly, moving the fence as little as possible. Everything that has to be cut X inches should be cut with one setup. It helps a lot. Thanks for all the other situations. You also explained how to use a kerf maker tool. Many thanks.

Not doing meth? Okay…

You guys rock. The editing is off the charts as well. Super channel!

Me: Literally the best way to start a video.

Also me: Literally the best way to end a video.

You guys crack me up š Very jealous of that square collection.

Don’t you like complicated maths?… use metric system. Good tips!

Reference measuring. Helpful animations. Thanks!

You guys are as funny as you are talented. And that darts analogy? I take it at least one of you is a shooter. Cooler yet.

That stop motion shot was slick š

As I always say, try and start out prefect worst-case scenario one will just be average

YouTube’s top recommendation after this video is Katz Moses "Measuring and Accuracy in Woodworking" š¤£

Great video

I just found this channel, as crazy as that might seem, but has quickly become my favorite woodworking channel…and not just by a little. Totally different "useful and needed" information then what others are pumping out. Excellent content.

Math: not even once.

My school teacher said that Iām not supposed to do woodworking Iām supposed to do math and it made me feel a bit sad that I miss out all the fun doing woodworking with my friends it made me feel left out š

I did it with Woodglut.

Maybe I’ve been working indoors too much since the unicorn virus…but that was awfully entertaining in my humble opinion. Thanks

the end of this video cracks me up. Also, thx for the tips!
