A video near and dear to my [machinist and mechanical designer] heart. I designed and made test fixtures for satellites, never a jet engine, but that didn't stop me from ordering a copy of the Aircraft Gas Turbine Powerplants textbook by Otis and Vosbury you frequently refer to. Why? Because you're a bad (good?) influence. And to top it off, a Futurama reference! My weekend is complete...
Spot on explanation for the need/manufacture of “special tools”. I have helped build test stands for aviation platforms, where only the component is available… test stand needs to be built/assembled as per the operating parameters of the component. B1 wing sweep actuator is a very complicated piece to be tested!
Thank You For All The Info. You’ve been an Inspirational & Instrumental Help For FAA Powerplant 147 Students and Instructors. Just wanted to thank you for all your videos over the year’s.
Jay, love this video. You are not far off from what we do with a billion dollar tooling budget 😂. 9:52 i was saying to myself where is the enerpac 😊. Sometimes we get lucky with slide hammers and “repurposed jaws”. Its really fun when a new mech puts the puller grove upside down. “CALL SHEETMETAL” 😂, tell him to bring a cutoff wheel and vacuum.
unrelated: this... this channel made my eyes wet... its beautiful. i should have known about here like a year or two ago. its a treasure. thanks a bunch!
I just searched YT for jet engine, and I'm not on the first page. I tried turbine engine, and I'm the third hit. More importantly, and this was a big reason for starting my channel, I was the first on YT to make vids about full size turbine engines. Summer of 2007 with the Orenda and the GE LM1500. First, and that record will never be broken.
I have a Temco circular punch that uses a very similar hydraulic pump and internal cylinder, and it's rated for 12,000 lbs. Punching a 2" hole into 16-gauge steel is effortless (almost no change in pumping effort). So when I saw you cranking hard on your pump to pop the ring loose from your engine, you get an idea of the incredible amount of force it takes to remove it. Kudos on the 3-piece jaws....very clever.
A Safety Blanket, Jay ! These things do fly ! Or Plexi, Rag,Anything ! Don't ask where my bearing shrapnel came from, or my brothers ! And a Manual is also a Tool , especially if it has pictures !
G'day Jay, Great stuff, Yay Team ! I don't often have to design and make the tools to do the job - but that was one of my father's favourite "party tricks". What I try to be a bit good at is using what's already available to permanently repair something I don't want to have to wait around to then pay a lot of money to replace..., and my most recent headache was also required to look as if it hadn't been broken. Tricky, with 3 Flanges broken off the black anodised cast-aluminium Light Mounting-Bracket, and injection-moulded plastic Blinker-Stalks, from my Electric Motorcycle made entirely of Hong Kong-ium... After the initial anastomoses was done, then I made Composite "Splints" or "Fished" Doublings, by serving around the Joins with 2-ply Nylon Kite-String, and applying Epoxy into the thus tension-wrapped Nylon Fibres... Blinker Stalks were tacked back together with Plastic Bond, drilled, sewn across and then Served with Kite-String, Epoxied over to splint/fish/gusset-reinforce the connection, and then mat black Paint brushed on to blend in with the Anodised stuff. 15 hours over 3 days, Jay, to let the Epoxy properly go off, one Joint & one stage at a time...; because one early-disturbed tacky component, dropped in the dirt, would have wiped out the entire possibility of reconnecting the pieces functionally - without making it look like Shite... In theory, Aluminium can be welded, but, not prettily ; and not delicate Castings, either. I posted some Videos of the process... Such is life, Live a good one... Stay safe. ;-p Ciao !
That conical ring kind of reminds me of separating ball joints, or maybe like axle nuts on older dodge trucks, we were able to use air hammers to vibrate things loose, but with that component I would fear damaging it.😊 The long 7/32” wrench you built maybe could be modified with a reversible ratchet wrench? I think it’s a sign of an advanced tech that can make their own special tools!
I will ask here. Can gas turbines (used in power plants) be run on liquid fuels like diesel/gasoline with slight modifications or no? So, are there examples of same model that run both on natural gas and disel depending on fuel feed system set at the time? What changes need to be done? Other things like combustion chambers can stay the same? Thanks.
Between the various liquid fuels, only adjustments are needed. Many industrial engines are configured to run on natural gas. This requires different fuel nozzle and fuel control. All other internal parts are fine with whatever fuel is used. Many industrial engines are setup as dual fuel, and some are able to switch fuel type while they are running.
A second comment - that pulling fixture for the split cone is very nicely made, my compliments to your machinist.
I always enjoy your videos. That wedge popping loose was startling!

That's gotta be a big rig!

Every afterburning engine test day, I have my coffee in my P&W Afterburner119 mug. It's the details that are important.

This was VERY interesting video!!!
Thank you for sharing the engineering behind the "simple repairs", which are of corse very far from simple :)
Most useful video, JZed

AgentjayZ that was a awsome video.
Awesome as usual, thanks

Working at the Montreal air museum i have to invent all kinds of tools to fix the planes.
at st.hubert ? 🙂

@AgentJayZ Fascinating, thanks for the info!
Removal of 7/32 fastener is free if you sign up for the 7/32 fastener installation package.
The critter you need is an Aye-Aye.
Can't imagine what a tedious job itst must be to fasten that nut using that tool.
Once you have the right tool, it only takes a couple of minutes. Finding the difficulty, designing and making the tool are what eats up your time.
