Making Joggles
Welcome back fellow aircraft builders and aviation enthusiasts! In this video, I show how to make joggles in the firewall steering rod covers, which are made from 28-gauge (.018") galvanized steel.
I learned how to make a simple joggle tool by watching EAA's Hints for Homebuilders Series (Joggle Video here: www.eaavideo.org/video.aspx?v=... ). In today's video, I expand on how to correctly size your homemade joggle tool for a specific part, and make the part according to the blueprints. This method works any place you need to put joggles in thin sheet metal. So far, the only other place I have found the need for joggles is in the landing light mounting bracket, but there may be more.
If you have not already checked it out, EAA's Hints for Homebuilders series is an excellent resource for all sorts of aviation-related tips and tricks, covering everything from electrical to sheet metal to composites. Check them all out here:

Never seen a joggled or step made like this before. Very clever technique. I was looking at how to put a shallow stepped edge into a car panel without using specific tools and your video showed up. 👍
EXCELLENT!!! Where were you 40 years ago when I started to work for Pan Am.
Super helpful video!!! Thank You So Much for taking the time to make this!!! Excellent editing too, video was straight to the point with no extra useless conversation. Great Job!
Thanks for a great joggle video. Able to make parts now for WW2 Grumman Wildcat under restoration in N.Ireland

You're very welcome, and thanks for watching. A Wildcat restoration is quite a project!
Great Video, Brilliantly Simple and will definitely help me - Many Thanks
Very good job. The best of the best video on KZread. 🤞
That's a good idea if you don't have a joggle tool, but watching the vid gave me an idea, you could make special shaped bolt on jaws for your vice and put the metal straight in and press.
Great video… thanks for posting
Thanks good explanation
I was about to say, gotta be a USAF Aircraft structural mechanic with all those clecos, combo square, and proper metal orientation when you bend your metals.
Nice 👍
How did you determine the 55mm length between bends? Was it some developed length magic? Thanks for your videos...totally great and explained well.

wgh15330 I made a couple guesses and then test pieces. But after you've bent enough metal, you get an idea of how to estimate dimensions like this. But test pieces...lots of test pieces.
Nice❤🎉
Gonna give this a try with 20 Gauge automotive steel for car repair, thanks for the principle

what kind of material are you using for the piece and the tool?.

Juan Leiva The steering rod cover plates are made from 26-gauge (.018") galvanized steel. The joggle tool is made from some spare 1/8" (3.2mm) 6061-T6 aluminum I had.
how did you joggle the elevator trim tab chanel?

My elevator trim tab channel doesn't have joggles in the plans. However, I used a set of crimping pliers to put a very slight crimp in the ends of mine and then manually bent the flange slightly lower, creating a slight joggle. Worked great.

@@wb6anp I had the same thing happen and my trim tab is now recessed about 2mm from the trailing edge. I'll be pointing out the problem in my update video on the elevator. The slightly-crimp-and-bend method worked really well for me.

WHAT are joggles used for exactly??

A joggle is a very slight offset in sheet metal. In my case, they are used in the firewall of my airplane to allow "covers" for the rudder control rods to move freely, while sealing the engine compartment from the cockpit. They are used in all sorts of sheet metal applications.

They are used when the edge of one part needs to overlap the edge of another part.
That's really informative. Thank you. Also, as a word of friendly advice, show a bit more enthusiasm in your introductory greeting. My personal experience is that the deadpan delivery doesn't generate as good a response as an enthusiastic one, even if the enthusiasm is faked. :)

How good are cleko’s

I'm not sure I understand the question. Clecos are the aviation and racing industry standard for use as temporary rivets during fabrication and assembly. I buy all mine from aviation supply shops but I've never had any issues with them. They work great.
