Put the square on against the circle and draw a right angle with the point right on the circumference, the two other points where the lines meet the circumference will be diametrically opposed, measure half way in between them and you have a centre. Simpler than this method, requires less tools, and is more accurate.
Any two intersecting lines drawn at maximum length must intersect at the center. Just put the circle behind a ruler and roll it past until you hit the highest it will go, draw a line, scoot the circle back and do it again.
At first I wanted to be a debbie downer on this idea, but then i slowly realized that this is very simple and efficient. I love it. Not often i say that about shorts.
Pic a square, any square. Attach - glue, screw, clamp - a board from the intersection, up to somewhere near the center between the two limbs. Lay the New Centerfinder on the circle, both limbs on the circle. Draw a line along the centered board. Turn the Finder about 90°. Draw another line along the board. If it makes an X, you're done. If it makes a triangle, center is in the center of that, and you're still done.
If you only had one square you can draw 3 straight lines across the circle at any point, doesn't have to be the diameter just needs to be straight lines (chords), and then you can take your square, measure each line you drew and make a point at the center, draw a line on that point perpendicular to the original line and where they intersect is the middle. A little convoluted but it you don't have two square like this you can make it work
It even easier to us a measuring tape. The farthest distance on a circle will go straight across the center so just pick any spot and rotate it until you get the longest length. Then just half that measurement and there's your centre. It takes seconds.
Trace it on a piece of paper, and cut ot oit. Fold the paper cutout into quarters. There's your center. Place the paper cutout onto your workpiece amd mark the center.
I had to go another route with a ruler and compass!! I had a circle traced on 1/4 Baltic birch plywood and needed to cut it out exact(find the center) with a router jig🤷♂️!!
You don’t even have to turn it 90degrees anywhere from about 20degrees to 160 degrees will do. You just need enough rotation to differentiate the lines. They always cross on center.
Or you can just draw three lines across it at the furthest possible apex of each side, and you'll have your center. The third line is verifying for mistakes in the apex.
Well that's a pretty good idea But when I need to know where the center is I just pull my little tape e- waypee out and measure the distance across and then divide it by 2. But I like your idea better
Reminds me of your really early vids when you experimented with multiple video cuts filming yourself speaking from different angles. They were hilarious. This was good, like peeking through the window. LOL
I can’t wait to forget this tip when the time comes that I need it!
Me got timers all too ahh all timers 2
It's the internet use the like button...
@@gilbertbrewer269 Interesting.
Can you elaborate?
@@LZRxHWK interesting
🤣🤣🤣
you can turn the circle any amount as long ad the intersection is apparent. great video!
Brilliant😎☝️ Thank you
Thanks 🤗🌹
Love these little tips. Never to old to learn something new 👍
Brilliant. This is what I was looking for, without drawing chords and then bisect it and so on.
Thanks for a very informative share
First short Iv seen that’s worth watching. Unfortunately all the other junk will make me forget this tip pretty quick.
Or with a ruler just rotate from one point until you find the highest distance. You now know the diameter. Half that is the centre.
I am totally making a dedicated jig for this.
Thank you!
Quick tip. Draw any 3 lines across the circle. Now draw a line perpendicular on all three lines. Where the lines intersect is the center
Good advice! 👍

So practical tip as always
Nice old school tip. Thanx.
We need more of this on here.
Real tricks and secretes of the trade. Not just some shitty hack.
Awesome tip.

Old is Gold
Very smart, i was doing in way more steps: perpendiculars to tangents, where they cross it's the middle
No...Thats not more steps as you're not buggering about getting a tool you don't need and clamping it.
Awsome! I'm in my shop preping a round 25lb weight, just needed to find the centre.

Not bad easy and to the point
Great tips :)
Perfect... Thanks
Thanks my friend

Great vid thx for sharing

Genius .can’t wait to try it out !👍
Thanks fir the tip Jepetto
I had to go another route with a ruler and compass!! I had a circle traced on 1/4 Baltic birch plywood and needed to cut it out exact(find the center) with a router jig🤷♂️!!
Thank you for this. I must remember this when I need to find the centre of a circle.
Thank you for your expertise.
You don’t even have to turn it 90degrees anywhere from about 20degrees to 160 degrees will do. You just need enough rotation to differentiate the lines. They always cross on center.
I totally needed this
Thanks for that.
Please never stop showing these type of tips and tricks.
Wow, thanks bud!
Or you can measure from one side to another dived by 2 and do it again
BRILLIANT!!! Thanks very much!
Gotta love Geometry!
Could’ve used this today! Thanks for sharing!
This is the best advice I'll ever forget when I need it
Or you can just draw three lines across it at the furthest possible apex of each side, and you'll have your center. The third line is verifying for mistakes in the apex.
Turn it again to any spot, and mark again. If the three areas intersect, the center is verified
This is brilliant. I’m going to make a jig for this, great for dowels as well
Note: it doesn’t have to be 90 degrees. As long as the two lines cross each other it will be the centre.
Ah yes Thale's Theorm, excellent tool of knowledge to use throughout life.
God bless you, Thales
Ty
Brilliant
Genius!
Actually turn any degree (doesn't have to be 90) and draw a line will get the center
Thank you Mr. wizard
Smart..👍👍
I just bought a lathe last week and this has been stumping me. Best tip I have seen so simple!!!
Hey nice tip
You sir is god sent
You must allow for 1/2 the thickness of the mark
- No annoying background music
- No text to speech
- No annoying voice
- Very informative
A good video.
🔥🔥🔥🔥🔥
Sweet
If you made a jig, great tip! But its just as easy to measure and do simple maths
Or measure the diameter and divide that in half...
Try to find the diameter for a shape with zero sides. Big chance you’ll be off by a degree or more
Thank goodness! I’ve always wanted to know where the center of a circle was!
Well that's a pretty good idea But when I need to know where the center is I just pull my little tape e- waypee out and measure the distance across and then divide it by 2. But I like your idea better
Or use the corner of two walls with the square
this is amazing... how do i save it?
Thumbs up
Awsome
Elegant
... as long the your working circle is small, and portable.
Thanks Colin. Now how do I find the center of a sphere?
Thank you boss man, now will you tell us about your wood watch please.
Reminds me of your really early vids when you experimented with multiple video cuts filming yourself speaking from different angles. They were hilarious. This was good, like peeking through the window. LOL
Wish I had more old guys like this in my life man
Wow
I guess, but doesn't that only work for circles that are a certain size.
mike stewart are a carpenter now!?😁😁😁
Love these one minute wonders
While this is true, you're probably better off by marking at least 4 at 45 degrees for a more accurate centering
Yup
ya and all you need is three right hands and four left hands and some one to make the mark for you
What if the circumference is 100 inches??? Your triangle will not work.
I new about this 40 years ago
Or use a piece of paper trace circle of the same size fold it into four equal pieces then use a pencil to indent the center... just saying 🙂
Why not just use a measuring tape? Measure the circle then cut the number in half and make as many marks as it takes to make you a happy person.
I'm always the center of my circle when I'm around a bunch of squares.. 😂
You don't even need to turn at 90° for that second mark, Just make another line to intersect the first one. Boom, done.
I thought it was the guy from Bark River knives. I’m sure I can learn something from both of them👍🏻
Ok... That’s actually pretty good
Huh, I fking love OGs
If you turn it 3 times, you can see your error (which should be close to zero).
If you have none of that... trace around the circle on a piece of paper, cut out the circle on the paper, then just fold it in half twice...
how do find the center of oval?
😮
you can do it with just a ruller
