- This is part 2 of 2 showing an overview of the full project. You should watch this video before you reach this portion of the lab. This project was specially created to give sheet metal students practice with a variety of skills as well as to meet the FAA requirements for SIU's Aviation Technologies program. Any resemblance to real aircraft, living or dead, is purely coincidental.
What’s the story with the finger?
"People who make damage to their airplane dont want to be reminded of that damage later" 🤣 Thanks for the wonderful video. I've only been working with aluminum at a hobbiest level - this taught me so much and gave me lots more to research.
These tutorials are absolutely brilliant! I attend an EASA part 147 training facility. We watch these videos as a class and the skills are very helpful. Thanks
Thanks. I'm getting ready for my SIUC tenure review, and if you/your class/your teacher would be willing to write me a letter with what you just said, I would help me be sure I get to keep my job!
Where is your video on making the circle patches
verry cool man, i like your videos because I learn something interesting :D good job
would countersinking work better for this repair instead of using a dimple die?
Question...in the SRM, there's the "typical web repair." 1, what's a web, and 2, what defines typical?? Thanks in advance.
Can you please make a video explaining the correct measurements for the same one inch hole. DME's in my are asking this a lot. A 1.75 distance between the outer rivets. A total of eight rivets around and they all have to be exact. Thank you for making this video.
Are you looking for an AC-43.13-1B explanation?
I think the one he covered was letter (k) 1” inch patch plate the distance suppose to be 2x from the edge of the patch but no more then 3x for rivet spacing am I right ?
What is the advantage of dimpeling over countersinking for the flush rivets?
Countersinking is much quicker and easier - particularly for the guy driving the rivet. You dimple if the sheet is too thin for a countersink to fit (the countersink cuts out of the other side of the sheet).
Sneaky beaky bird. Swack!
:D
i just have one question sir? Is it okay to use a squeezer with universal die sets when attaching the filler piece to your doubler?
How did you make the small one inch patch. I assume by getting it close on band saw then filing to a circlular line? PleaSE HELP. THANKS
Sometimes the rivets ar placed in a staggered pattern.
Could yu kindly explain the advantages of the staggered riveting over the chain riveting?
Hello mr can you replaced wind shield 209 Helicopter
Can I ask what are the tools did you used to this video? Thankyouuu☺️
Removed antenna and I have a one inch hole to file
the hank hill of airplanes
And the edge distance
can you do one on the octagonal patch
Bro what
Very good
Does grain direction not matter in a flush patch? Does the grain direction have to be in same direction as original structure?
Grain direction typically is not considered important on sheet metal parts unless bending at near the minimum bend radius, where bending across the grain is preferable. I usually pay attention to it in my projects because when left uncovered, it can be visually jarring if the grain runs different directions. I also try to use rivets from the same batch, because some have slightly different coloration...
@@1donagin thank for for getting back too me! Im taking my airframe Oral and practical at the end of February. So been watching your videos! Trying to relearn bend allowance and sightlines
In an actual aircraft what no. of rivet should be used? Ty
Depends on the aircraft, the thickness of the material, the type of material, and the location. Most small aircraft use AD rivets, approximately three times the thickness of the thickest sheet. Your aircraft manual should spacify.
1donagin thanks for the info
Can you show how you determined the spacing of the rivets for both 1" and 2" circular patch ?
Hi. The 2 inch circular patch rivets are determined by the repair manual. See AC-43.13-1B (downloadable for free), or the Cessna Structural Repair manual. Both specify the spacing. The 1" inner patch is simply a scab to make everything flush, and so the spacing is not critical.
@@1donagin Would that be the 45 degrees indicated in the structural repair manual , for the spacing ?
@@tajaheedwards1516 360 divided by 45 gives you 8...
@@1donagin Thank you and how would you determine the edge distance or calculate for the 1" and 2" patch?
You will see that the manual tells you what diameter circle to put the rivets on. It also tells you the hole diameter and the doubler diameter. Do the math, and the edge distance will come out correctly. If my memory is right, AC 43.13-1B calls for a 2.5 inch doubler on a 1 inch hole, with the rivets on a 1.75 inch circle.
