Now draw a perfect square with a circle

The reasoning for there being a circle is because of a mathematical principle: if you have a circle with a drawn diameter, you draw a point on the circle, and connect the point to both ends of the diameter, the resultant triangle will ALWAYS be a right triangle (provided you don’t get clever and draw the point on the diameter, ‘herp-a-derp it’s not a triangle it’s just a straight line!’)

Love it. Very enterformative

Steve, I love your humor. I am one of those that miss the project videos, but after watching your video on the topic, I get it.

use painters tape. nail one side into the wood, then poke a pencil through the other end

That video was hilarious, keep them coming Steve

that was fun, Steve’s old humor shines through! 😀

Nice video, never thought about using it this way

this is actually very commonly used math theorem called thale’s circle. Did you know that if you connect any point of that circle with those two points they will be in right angle? 🙂

Like the masters, I use a chisel and remove everything that isn’t the circle.

Perfect timing. I recently used that exact riler and was wondering about the purpose of that circular area

Finally. The perfect reason for shorts!

You can use a very similar trick to find the exact center of a circle. 1) Draw any random right angle inside of a circle. 2) Connect the points where the ‘legs’ of the square intersect the circle, giving you the circle’s diameter. 3) Repeat (1) and (2) in a different place on the circle, and you’ll have drawn a 2nd diameter. 4) The place where these two diameters intersect should be very close to the center of your circle.

(You don’t actually have to draw the right angle, just using a framing square to find your points and draw the diameters is faster. But small errors multiply with this and it’s easier to understand what your doing and see if you’re a bit off if you actually draw in the angle to start)

I find this really useful when using hole saws to make cut outs for things to fit into (pipes, lights, etc). Trace the thing you’re cutting the hole for, find the center, and you know exactly where to put your arbor bit without having to eyeball it.

This is funny stuff Steve! Perfect for a Saturday! 🤣🤣

Thanks. Theoretically I always knew this was true but until now I never seen anybody do it. I’m sure I will use it some day. If I need a round hole between two points it’s easier to do it this way than to first find a compass, find the middle and draw a circle. Lets just say I have specialist equipment in my toolbox I probably will use less than this quick and dirty trick.

This short was good enough to finally actually make me like shorts. You are awesome Steve!!!

These are the types of videos that I subscribe to WWMM for.

Thank you, Steve – you always improve my mood; this was a nice one.

Damn I really could have used this last week when I was finding the right bowl to make a wood cut

Fascinating. And all this time I’ve just used a plate. Great short, Steve.

That circle is accurate enough for practical carpentry, for example, if you were going to cut a hole in a piece of drywall using a utility knife.
