how to find the degree of an angle using a speed square

[mechanicalman]

Ok everybody, finish carpenter with decades of experience speaking here. He is right, you set the miter saw at 30, whether for a butt or miter joint. This works on a miter saw and this is good a practical carpentry tip, not a geometry demonstration. The complete angle is 120 [90 + (90-60)]. This is because when pivoted that way it is reading down from 90, not up from 0. But the goal was to make the cut, not know the angle.

Saved me some money on an angle finder. Thanks!

The speed square is one of the most useful tools ever invented.

I generally like to set the thermostat at 70 degrees

I have a couple angle finders but never hurts to learn more! Along the way!

I feel like most YouTube videos show you but don't actually teach you anything. Most older men seem like they dont want to share knowledge either maybe because competition or pride i dont know but thank you. That was a nice quick lesson. Not sure what to do in life but building my own tiny house would be nice to know how to do. Easier said than done.

Thank you
This was so helpful
I had to find the angle on a wall for a job quickly and this really helped

you explained the shit outta that speed square yo

Another use for a speed square. Never knew about that one.

If you cut 30 degrees from 0 on the chop saw, it leaves you with a 60 degree angle on the trim. 30 degrees is the offcut. Do it the other way on the other piece and you will have a 120 degree angle. 30 is the angle of the cut from 90 which is 0 on the saw. Wait, maybe I'll get my son to explain it to me. He's a plumber.

He’s not finding the actual angle of the kick-board, i.e., 120°; he’s actually finding the angle of the two cuts he needs to make on the replacement kick-board... i.e., 2 x 30°

If the EXTERIOR angle is 120°, then the interior angle has to be 60°.... so 60 divided by two [cuts] Anyone?

[lopez]

how about finding inside angles on crown molding?

[paulerickson]

So many things I don't know. The older I get the more things I find I didn't know. But I know now. Trick is not to forget it.

Serious question: isn’t that angle 150°? Wouldn’t each of the cuts for your trim need to be 75°? I can’t seem to figure out what this guy is saying in the video.

[scottmcgrory]

The look on his face at the very end of the video is priceless. You can tell he just figured out "wait a minute, that's more than sixty degrees..."

[rodolfogonzalez]

I agree that this is wrong. The angle you get is 120 degrees so you make two 60 degree cuts. The miter saw is set at 30, which yield a 60 degree cut.

[ahhsk]

On a fresh piece of quarter round, if you make a 30 degree *cut* you are left with a 60 degree *edge* on your quarter round.

Great video! Quick, and to the point. Love it!.

[robjworkshop]

Brilliant! Thank you, but what was that noise??

[mubjcfh]

I actually understand…. to a *degree.*
