mikesinventions.etsy.com Making Cone shapes can be Frustrating. This video shows you how to lay out your flat pattern so that you can wrap your own frustums. (frustra? Frustrices, Frustri, frustum...) Need to make a traffic cone, cyclonic dust separator, conical nozzle, rocket body part, air duct, horn, siren, lamp shade, and other similarly shaped item? Well then, a frustum is what you need. I'll show you how. A frustrum is a truncated cone that can be flat-wrapped from any flexible material, like paper or sheet metal. They're found everywhere, and knowing how to make your own makes you a better person. Since you've read this far, I'll give you some help. You can download an Excel file that I made and will do all this for you.

After watching you do this math in your head, I just realized I’m too dumb to even make a dunce hat 🤪

@donnachaobrien90 Год назад

"If you look at this for half a second you'll be able to figure it out." This guy is vastly underestimating how dumb I am

Had the impulse today to build an apollo LEM out of cardboard, then realized that high school geometry failed me and I had no idea how to make a pattern for the conical engine bell. Thank you, this was a big help!

Mike good job. One comment though. Once you know the length from the center to the large end the angle can be found by dividing the large circumference by that length. It is called “radians.” Unfortunately this is not taught well in US schools. If you do not like working in radians you can convert the angle in radians to degrees or even gradians. Your choice. One full circle is either 2 pi radians or 360 degrees or 400 gradians. 1 radian = 57.2957° Convert to your hearts content.

@kerrymcinnes1240 4 года назад

Could you possibly elaborate on that please? The large circumference is 6.08*pi*2* equals 38.182. the length from the center is 6. 38.182/6 equals 6.363. 6.363 *57.29 equals 365. Im confused

Great for custom model making

@feathers352 9 месяцев назад

This works but I have an old sheet metal formula that works great. Take the large diameter and multiply it by the height. Now divide the result by the difference between the large and small diameter. The result is the swing point at the top of the cone to swing the arc for the pattern. The only downside is takes a bit of space to swing the arc. I just put marker on a piece of string.

I'd like to make a cone shaped wood table base. Do you have a formula for calculating the cut angles for each piece of wood?

@MikesInventions 2 месяца назад

Oh no I don't sadly. I've never needed to do that. Maybe I will some day. Thanks for watching though.

I am constructing 12 equal concentric circles on CAD. 144 is my outer diameter. I want to put the rings to different angles such as the angle of the great pyramid of Giza at 51.82729237 degrees. Imagine you are looking at the rings from a top view. The rings are actually a cone. What should my diameters of each of the 12 rings be? I want to make other cones from a top view using music harmonic ratios such as 1:2, 2:3, 3:4, etc. I am using a Phi Pyramid where the height equals the square root of Phi and the slope angle equals Phi. On your calculator you can take the Sine of 18 to get Phi, multiply by 2 and add 1. Thanks for your comments.

Hey Jake! I don’t think I understand your question. Sorry for the late response. Did you figure it out?

@spurstrembly9521 3 месяца назад

I if I know th measurements. Do I need to multiply? 18 inch tall. 12 inches at th top. 18 inch bottom. Mine are concrete forms.

@romandybala 2 года назад

I understand the words you are using but not the total equation. I recently made a pattern out of stiff card for a motorcycle exhaust megaphone and I was able to achieve the shape I needed with only a ruler and a large compass.

@4tonylee Год назад

the percentage math dosnt work out i wish i could see you input on a calculator Thanks

@porker5749 4 года назад

Mike: How did you get 59.18 degrees by dividing 6.04 into 38.22?? I did some further research and found that the percentage of 6.04 is of 38.22 = 15.9%. I then found an on-line calculator that gave me the percentage of 15.9 for 360 degrees, which equals 57.24 degrees. Any chance you can walk us through the math as to how you came up with 59.18 degrees?

@kerrymcinnes1240 4 года назад

Im coming up with the same thing. I still dont get how he came up with the 59.18 degrees.

@vrajagrawal4523 4 года назад

Its 6.28 divided by 38.22

@MikesInventions 3 года назад

Hey there. Sorry for the late response. This one slipped past me. 6.04/38.22 is about .164 of a complete circle. Then this *360 gives the 59 degrees needed for the cone arc angle.

@porker5749 3 года назад

@@MikesInventions Thanks for replying Mike, but I'm still confused. If you divide 6.04 by 38.22 the answer is .159079.... x 360 = 57.26°. What am I missing here?

@MikesInventions 3 года назад

Hmmm... I don’t know I did it on excel last night and it worked, and now I check it on my phone and you’re absolutely right. I did something wrong somewhere in video production. Anyway, I used this all as recently as yesterday to make something out of sheet metal and it works. So just ignore my math I guess and focus on the procedure. Oops! Or download the excel file from my website and you can forget doing it all by hand. Thanks for catching the math issue. Still no clue what I did there.

@Diego-tp9ib 4 месяца назад

I think there is one mistake in the video, you divided 6.08/38.22 instead of 6.28/38.22 to find the percentage of the circumference...

Hello I am desperate and i was wondering if you could fix my ipad 6th generation because the home button fell off and now i can't even use it so i was wondering if you could please help me. I'm having a panic attack because all of my info is on it and if i lost everything, it would be bad.

@user-pf5in2km3v 4 года назад

The home button is basically unfixable if it breaks, transfer your data out of your iPad, and take it to a repair store

Well I kind of understood the concept and I'm not that bad at math I'm better at geometry, and I also have synesthesia I'm able to look at things in quite a different way oh, I'm sure you're probably familiar with it, but as I said I got a little confused but you know what I am subscribing because I think I could learn something from you and I like that, and I like the way you presented yourself

@MikesInventions 2 года назад

What a nice comment Carlos! Thank you so much. Glad to have you on board!

@orionmec 2 года назад

Yes this is how... but you do not show the math. Using numbers that you can figure in your head does NOT help anyone do this to dimensions. It is Simple Trigonometry however. Here is where you lost me... When you figured theta! What is the formula for doing this? And r1.... r2... PS... Sorry but I read some of the other comments and it is clear that you were not clear.... show math please!
