I then came up with the idea of making and OOB to put next to the Whiff - but that effectively doubles the price of my builds. 

Yup to that. Frustrating, but then when you find that one (or two) person(s) who knows what they're looking at, it's a definite boost.

And yeah, a thought, but an expensive way to do it - and double the work, for not much gain.

Quote from: Scotaidh on March 08, 2024, 01:35:49 PMWhen I built my J79 Cutlass I did a ton of research - reading pilots' stories, and so on.  Turns out that not only were the engines - the only ones available at time of build - not powerful enough, but Vought built it with a 3000psi hydraulic system - which operating pressure was more than double what previous &Y in-service Naval aircraft used.  So when an original piping part failed, it was usually replaced with ... something already in stock!  (Tell me you didn't see that coming!)  A half-inch fitting is a half-inch fitting, right?  So now you had sub-spec parts just waiting to fail and spray hi-press. oil all over the insides of the aircraft, including those oh-so-hot internal afterburner nozzles ,,, Can you say Fire!  I knew you could ...

Well that certainly explains a lot.  For a company that built the F4U Corsair, I would have thought Vought engineers would have known better than to pull a shenanigan like that, but I suppose not.  I looked up your J79 Cutlass build on here, and I have to say, that is a fantastic piece of work.  Makes me want to do one myself, once I finish my F-14E, F-15X, and F9E   

That sounds pretty crazy. I spent a lot of my working life using 3000 psi hydraulic systems and the LAST thing you'd do was fit and under-rated part or seal in a system at that pressure!

There's a LARGE circular stain on the wall of the Control Centre at the Railway Technical Centre in Derby which was the result of someone (not me....) doing just that, thinking that 'Oh, this one will do'. It didn't, and the wall mounted phone that used to be there was reduced to dust by the 2" diameter jet of hydraulic fluid that impacted the wall....................

Lucky no Human was in its path, just a phone.

Yeah I read stain and got worried there for a second

That was pure fluke, the queue for the tea trolley was just forming when the fitting let go, and the jet of oil went behind the last guy in the queue!

Apparently I shot down the spiral stairs from  the Control Centre without actually touching the stairs with my feet, leapt over a large pile of ballast weights and punched seven bells out of the E-Stop button to turn the pumps off. I can't remember doing it, but we needed a new E-Stop button and I had to go to hospital with a sprained wrist.

That was good - Someone was watching out!

And yeah, adrenalin can let you do some surprising things... all the bodies' safeties come off and well, Amazing Happens.
