Thank you! This is the exact info I have been needing for years. No more laying out arcs hit and miss with strings and / or any round object that is close to what I need.
Thank you! That was helpful. Although you explained the formula very well in words, it should be shown as: (((W/2)^2/H)+H))/2 (where ^2 means squared and, the difference being that formula shown had H/2 before being added back in, where that doesn't match the well explained description.)
Thank you. You stepped that out in an orderly manner making the geometry relate to the formula. One thing though...last formula shown should have brackets [(W/2)^2/ H + H]/2 because “the order of operations” would change your intended result.
4:30 Is there ANYWHERE you can just get arch patterns in various sizes or a kit of a range of sizes like shown? I'm looking for a range of sizes to determine the different sizes of trees in my yard & the best fitting arch to fit against them to build off of
All you need is to know the diameter of the tree. Then get your Center mark off of that measurement put a pin in it with a string tied to it and the pencil at the other end use it like a Compass
@@builditorfixit really helped as I've t draw an arch for a garage door tomorrow could have used it two weeks ago for an entrance wall but we done it the old trial and error way 👍😎😎
Thanks I am making a curved railing for my porch. A friend suggested a template made out of card board but still doesn't seem right. So I decided to use math and with your help I'm confident it will turn out nicely! But now I'm having thoughts that this equation will take me to the edge of the porch floor. A1=4.5' AND A2=4.5'. B1 is from center of cord to edge of porch floor. B1=35" I really don't want railing at the edge. I would prefer railing to be back some. So, Im going to revise B1 to 32" and make my template out of plywood.
I’m assuming you already have a curve in your deck. The first step would be to chalk a line between the start and end of the curve, mark the center, measure from center to top of curve and find the radius to draw your arch. If you want to move the railing in a little shorten the arm your using to draw the arch but don’t change the original radius point.
So you couldn't leave a link to the other video? And was it necessary to say ballz? I was going to like And subscribe until you didn't leave a link in the description
@@mikej2029There is a formula to find the tangent angle of the curve but then you still have to mark it and that is easiest done with a level in the opening or laying it out Then you have to cut it which is also done easiest by lining it up with the blade and using a glide fence.
It's suggest fixing the equation when written out for proper order of operation, if you punch that into a calculator that takes full equations you'll get ( (W/2)^2 / H + H) / 2 If I use W = 72, H = 6, the correct result comes out at 111, but without the extra parenthesis it comes out to 219.

Awesome!! Glad it helped!!😁👍🏻

Quickest sub I've ever made. This is EXACTLY what I was looking for.
Thank You!! Glad you liked it!!😁

Whata mad lad thanks mate 😊

Not that I’m aware of, but now you know how to make any size!!

Good information thank you
Thanks. Well done
Sir Really Thanks ,I am going to apply today on a site , Thanks a lot
Thanks, Glad you liked it!!😁👍🏻

Great breakdown, saved me from having to ask my smarty pants engineer wife. Only thing is at 6:30 it should divide everything by 2, not just H.
can you tell me how to divide a circle into equal parts using a formula and explaining it?
Thanks for watching, I’ll but that on the list of videos to make. 😁
Thank you.

VERY NICE!
Thanks!!
Say the arch in your video is a door header. How do I find the angle to cut header and jamb to match?
The simplest way would probably be to lay it out on the floor and mark the angle.
I was hoping you could give me a more exact way with square or angle finder. Your suggestion is what I was taught and only way I’ve seen.

Something practical to go with this waffle makes things easier to learn
Glad to hear it!!😁👍🏻
Beautifully simple thank you my eyebrow Dormer thanks you

Aweso
E thank you
I was lost after 5 seconds lol
Don’t worry about that just keep watching, each time it will start to click and make more sense!!
Your rise sq. + 1/4 span sq. ÷ 2x rise. = radius

Like a 745 over my head.
Did you really say "balls accurate". 🤣🤣🤣
Math is hard
Didn’t we learn all this in second grade?
Then why are you watching it?
I forgot bro chill
Considering you are now in third grade, you probably can still remember it.
😅
Lol this video🤣
