How to Calculate Rivet Diameter
มุมมอง 5Kปีที่แล้ว
The First Rule to Select the Proper Rivet. Always Start with Determining Diameters.
Awesome! thank you sir
Thank you, but what about the transverse gauge? how is that calculated?
Transverse pitch is typically calculated at .75 of the pitch for the adjacent rows.
@@jayharbert8481 Got it, thanks so much for your prompt response.
Thank you!
This was an awesome tutorial on these calculations
@@Checkered_Demon00 Thank you. I'm glad it was a help.
What’s the edge distance for all common rivet holes, and common hi lite holes? (Cheat sheet)
@1eltonio29 the general rule for edge distance is. You have a minimum of 2 diameters. Preferred is two and a half diameters, and maximum is considered to be four diameter. I cannot say that the same applies to high locks.As they are considered special fasteners, and may vary from the general rules from solid rivet. Thank you for watching the video.And I hope this is helpful.
This is the easiest tutorial for pitch and edge distance ever, you’ve saved me a lot of time trying to wrap my head around it haha! Thanks!

Will this be on the test tomorrow?
Your mistake was mostly that 2 times pi is 6.28.
Nice video serries! One important correction: .2675 multiplied by 16 is 4.28. So the correct rivet length for this project should be rounded up to -4.5, (not -4, as you miscalculated there). Thanks!
Thank you for the catch. I will make some changes.
Great and very comprehensive video. Question... when you multiplied the 1/16, you used .265 instead of .2675. Is there a general reason for that? Thank you and I enjoy your content
He just messed up. He should have calculated .2675 multiplied by 16. Just a simple error on his part. So the correct rivet length for this project is 4.5
Im confused about the difference between the pitch and the transverse pitch
Purchased space between rivets and the same row and transverse pitch is the distance between rows.
Make more video's please
Amazing teacher!!! I enjoy your education videos sensei it has helped me in life
Thank you for the kindness.
HI JAY WHERE DID THE .0625 COME FROM PLEASE EXPLAIN
The rule is to add 1. And. 1/2 the diameter So he did it as Add 1 dia which is +0.125 And then add 1/2 the dia (1/2 of 0.125) is = 0.0625 Put together you get +0.125 + 0.0625 ....................... You could skip this by saying + (1.5 * Dia) Where multiplying 1.5 takes care of this But I imagine he just wants to make it clear that you add 1 Dia and then 1/2 Dia By breaking it up into two steps
Thank you Mr. Harbert, your videos have been very helpful in tandem with the 43-13
I'm glad it was of use to you.
Hello Sir, Thks so much for you deplicted and comms: (international student?)/If i can allows myself: the Diameter of the Rivet should be equal to three times the thickness. You take one Diameter that's true but add just 1/2 you forget to take one diameter supplementary. If because i m on the review about the sheet metallic. Tchiouz
How do I calculate a 4/32 rivet. What is the shop head and height and width! Thank you can you provides steps
A shop head on a 4/32 rivet is 1 1/2 diameters wide and .65 to 1/2 diameters tall when finished. That is the same rule for all solid rivet shop heads or buck tails, Convert 4/32 seconds from a fraction to a decimal, and it will be .125. Multiply 0.125 × 1.5, and you will end up at 0.1875 wide or 3/16" Multiply 0.5 times your diameter. At point 125 and you will arrive at .0625 or 1/16". Hope this helps, and thank you for the question.
Hey Jay! Thanks for both rules in Rivet calculation... What about the hole size (diameter) on both plates of the stack?
The hole size is based on your rivet size. Each rivet diameter has a corresponding drill bit diameter to drill the hole. The hole sizes are not going to be in fractions. There are a lot of charts available that will give you the exact bit size based on the rivet being used. Typically you would be using number or letter bits.
Hello sir, can u make a video about calculating the number of required rivets? Here's a sample question for your reference: How many MS20426 DD 4-5 rivets will be required to attach a 10"x15" plate, using a singlerow of rivets, minimum edge distance, and 4D spacing? the correct answer is 56
Yes pls make video for this
How would you tell if you need to use MS or AN rivet? Is that found in AMM.
In the more standardized manuals the Hardware's often spelled out. Some of the older manuals did not do as good of a job. Many of the AN numbers have converted to Ms so you would take some of the older data and look at what the current code would be. All of the An numbers have converted to Ms numbers on solid rivets. You can reference many of the current numbers in the current ac43. 131b
This is great to understand the principles, but in reality this is all calculated for you in the SRM
I agree in most cases. For AMT students, they must be able to make the calculation to pass the class. Many older aircraft do not have comprehensive SRMs and the rules would need to be applied to select the correct rivets. Modern aircraft do have much better publications which eases the process. More on this can be found in th AC 43.13-1B.
thanks for the info. im new to this and learning
