Triple joined weld

[motolife313]

This needs to be air tight. It’s going on a airplane. Do you Think it will be ok doing it in 1 pass? 16 gauge 304

What is it for, intake, exhaust, just air ventilation? If it is anything related to the engine I would not touch it but I know I am not as good a welder as you. I would not want to risk being blamed for an engine failure in the event of a crash.

That being said, how much tolerance do you have or were you given for any warping?

It’s for the passengers so they can talk to each other with out yelling. A string will get attached to it and they can pass it to the middle of front of the plane and have conversations. I’m making 2 and string will join the 2

[CAVEMANN]

Wouldn't 2 tin cans be cheaper and easier??

[motolife313]

I’d think so myself. There’s a guy around here named sausage450r that does stainless work on helicopters he’s probably done this before

[searcyfarms]

i vote for pork n bean cans, eat beans first then discuss the outcome over string, if you really need to get some mileage then use a folgers can, you do realize you might need left handed cans and female ones with mufflers

A string? Really? Just wear radio headsets. I don't get the reason for the baffle? You're using it for a space that the can strings go inside? Seems like the ultimate Rube Goldberg contraption to make something easy incredibly complicated.

Btw, nice Harbor Freight tape measure, you can never have enough of them.

I think he's joshin' us...………...it's probably an incredibly Top Secret part of the incredibly Top Secret Macerating Toilet used by NSA dooooods that can't even take a 'comfort' break whilst capturing all our information, and tracking our whereabouts. We'll know for sure when he adds the padding around the rim.

Duhh.... one's mouthpiece, the other ear.

I've seen these before, I wouldn't supply the string... make the customer get it because this is where it gets expensive!! to work properly you must use a special graphite/kevlar/CF composite string.

So you're an airplane mechanic? Here, maybe this will help:

Qantas Airlines -

After every flight, pilots fill out a form called a gripe sheet, which
conveys to the mechanics problems encountered with the aircraft during
the flight that need repair or correction. The mechanics read and
correct the problem, and then respond in writing on the lower half of
the form what remedial action was taken, and the pilot reviews the gripe
sheets before the next flight.

Never let it be said that ground crews and engineers lack a sense of
humor. Here are some actual logged maintenance complaints and problems
as submitted by Qantas pilots and the solution recorded by maintenance
engineers. By the way, Qantas is the only major airline that has never
had an accident.

(P = The problem logged by the pilot.)
(S = The solution and action taken by the engineers.)

P: Left inside main tire almost needs replacement.
S: Almost replaced left inside main tire.

P: Test flight OK, except auto-land very rough.
S: Auto-land not installed on this aircraft.

P: Something loose in cockpit.
S: Something tightened in cockpit.

P: Dead bugs on windshield.
S: Live bugs on backorder.

P: Autopilot in altitude-hold mode produces a 200 feet per minute descent.
S: Cannot reproduce problem on ground.

P: Evidence of leak on right main landing gear.
S: Evidence removed.

P: DME volume unbelievably loud.
S: DME volume set to more believable level.

P: Friction locks cause throttle levers to stick.
S: That's what they're there for.

P: IFF inoperative.
S: IFF always inoperative in OFF mode.

P: Suspected crack in windshield.
S: Suspect you're right.

P: Number 3 engine missing.
S: Engine found on right wing after brief search.

P: Aircraft handles funny.
S: Aircraft warned to straighten up, fly right, and be serious.

P: Target radar hums.
S: Reprogrammed target radar with lyrics.

P: Mouse in cockpit.
S: Cat installed.

P: Noise coming from under instrument panel. Sounds like a midget
pounding on something with a hammer.
S: Took hammer away from midget.

Well i welded it out today and the double joint welded just fine. Settled in at 80 amps or so for the outside of the tube. Can’t post anymore pics becuase this will be patented soon and don’t want to give any ideas

Ronsii we are supplying the string

Now that actually did make me laugh!

STFU and we B flyin' !!!

Ooooo you're gonna supply the string.... that's probably a mistake... gonna cost a chunk o' change as most supply houses for that kind of thing only sell it 1,759.79 yd. spools... I don't think any of the suppliers we used to use will split one anymore as they got stuck with too many 'open' spools of different grades in the past.

One more thing to remember is there are at least 20-22 different grades of the comms grade string - depending on your application if it is piston powered or turbine... grade ls43 is only for piston while la43 can be used on either but also if this will be going in a pressurized craft then you don't need the altitude compensating which is usually denoted with a '-AC' suffix on the grade number and costs about 50 percent more. any which way it's going to be a bit costly!!!

My theory is it's for military aircraft. There are experts who believe a certain weapon exploded in the right place will destroy all electronics. These aircraft will switch to analog. Diesel engines with the simplest fuel system need no electronics at all. Tin cans, and string will serve as communication even in nuclear war.
