Thank you for a great answer to a mind bending question! Been frying my brains how I going to space clock numbers out accurately. This looks lovely and simple. 👍
This is really simple and extremely helpful . Thank you so much
You, Sir, are a genius! I recently moved and took my chrome ball wall clock with me. On reinstall in my new place, I was OK with the 4 quadrants (12, 3, 6, & 9), but when it came to the minutes I completely forgot how I did it the first time. I do know it was a lot more complicated than your method, so I gave yours a try. Easy-peazy! Thanks so much!
That was awesome. Thank you.
Very impressive and easy way to do this.
Saved me thank you
Thanku so much..really easy when u know how 😅
Much appreciated 😃
This is the best!! Thank you
Mathematically there is one major problem with this method. You started out with a big step already done - the horizontal and vertical demi-chords. While that will work, it depend on how accurately you draw them. So how did you accurately lay them out?
One answer is to not even bother. Instead, simply use the compass to mark out the even hours, and then bisect one of the angles they create, say the 12 and 2pm angle to create the 1pm position on the diameter. From there, mark out the remaining odd hours.
Doing it this way will ensure there is no error in the way you layed out the initial criss-cross which would make every other hour inherit the error. The key is to use a sharp pencil and accurately place the compass point in the center of the circle line.
That was my immediate question; thanks for that.
OMG compass Is very big!! where can i buy it? I have never seen one so big
@@Wood thank you! 👍🔝
I need one compass plx send me
Let me guess. The people that need to watch this to learn how to divide a circle into 12 equal length arcs funked simple Geometry
As it looks like you have "funked" simple English. 😄
I’m so freaking old, I don’t remember if I flunked Geometry.
It's not as easy as you think. I've tried 4 different times on a sheet of 10" x 10" paper, and can't get them lined up equally. I'm making a clock face, so this is a crucial part. This is spot on... it's the first 2 lines that are the issue - N-S, E-W. That has to be spot on. Take a piece of square paper, fold in half and half again. That should give me the N-S and E-W to get me going.

Take your combination square and find the center point and layout your cardinal points (12, 3, 6 and 9). Use your compass to draw your circle. Then starting at the intersection of the circle and 12 and three draw six arcs of the same radius as your circle. Or draw six Arcs stating at 12 and then bisect three of them drawing a straight line through the center. This isn't rocket science.
