Looking at the C-130 fuselage disappearing into the belly of the C-5
above reminded me of a somewhat similar photo involving a good buddy's newer
GMT800 3/4 ton Chevy pickup (with the tasty 8.1/Allison combo) ...and
in the bed is the decommissioned shell of one of my very favorite street legal
'go kart with a license plate' -- The Mk. 1 ('78-'80 here in the states) Ford Fiesta:

Q: Why is this on-topic for the safety wire thread?

A: Prior to losing the car to rust (ie: air where metal should have been for one
of the front suspension connections) this was an ultralight sleeper. 1600cc crossflow,
upgraded to big valve head, 'fast road cam', 4-1 header, lightened flywheel, engine
lowering kit to improve CG & straighten the halfshaft angles, always tuned to juuust
this side of peppering the spark plug insulators, full suspension upgrade including
adding a 19mm rear sway bar from BAT (British American Transfer) all sitting on a
set of Ford of Europe 13"x6" steelie rally wheels shod with sticky 185/60-13 Yokohamas
in the summer, and Hakkapelitta directional snow tires on the original 12" wheels in the
winter. (The paint was worn off of the handbrake between the seats in the winter...and
yes, I kept the e-brake cables adjusted to perfection. Of course these memories fade
with time, but on the snowier days I think I spent almost as much time looking out the side
windows as the windshield itself? It was ridonkulus. :0)

it was an 1800lb ultralight that punched way above it's weight. This was back in the day when
the old VW Rabbit GTIs were comfortably sitting at the top of the hot hatch pecking order,
especially when compared to a bone stock US-spec Fiesta. (Think Mustang vs. Camaro kind
of natural rivalry back then.)

All the time spent putting go-faster bits on in the driveway was worth it...when the
GTI guys would start it while wearing their best smug mugs...only to have the expressions melt
as I finished it by wailing away into the distance, revving that motor to infinity & beyond... :0)

Mechanically, the drivetrain was all but unbreakable -- the harder you drove them,
the sharper they ran. Only cars I ever owned that I never bothered to install a radio.
(And I love music.) That motor wailed like the powerplant in your favorite motorcycle.
Thinnest sheet metal I'd ever seen up to that point. One of my discerning buddies
remarked after slamming the door & hearing the tinny Whaaaaang' that it was a
Tuna Can on a Skateboard. The whole interior was stimulated by the engine when
it was running, so Engine operetta through the twisty mountain roads all the way
to work. Same-same on the way home. So much dirt-cheap fun!

...but I digress. Remember Erik the Awful's story about the BMWs that they were
racing were loosening the bolts on their CV axles? Well, on the mountain roads of
VT I managed to stimulate the same exact failure in my warmed-over Fiesta.

I thought the first time was an assembly error on my part, so this
time I just put everything back together (always using a torque wrench)
but this time with loctite & went on my merry way.

On the 2nd failure (on I-89N IIRC) fortunately I had a baggie in the back with
some 'just in case' spare bolts and barely managed to get it running before
the snow storm hit. (mea culpa: Schurkey, I am 99% sure that I did not use
the Loctite activator/primer, my bad. :0)

My permanent fix? Safety wire. (I was happy that the fasteners were metric Allen bolts,
(aka: Socket Head Cap Screws) which made drilling the holes for safety wire
at least 10x easier than a conventional bolt head.) Problem solved, lasted
all the way to the decomissioning ceremony seen above.

So, between the safety wire story plus the Chevy truck doing a pretty decent
C-5 imitation, I think that this really is the best place for my tale of Go.

Ok, the cart that was powered by a turbine, would out put electrical or bleed air for starting was dash 32, -32 ?

In some areas or attachments there are special washers can be used for a " secure positive mechanical locking feature ". A few out of my hardware drawer. Tabs to lock on flats, with opposite tab in a hole, notch or edge. The other, tabs on flats as the arrow point is against perpendicular surface or hardware.

Re: Stealth safety wire.

Here's one of the favorite photos I took while visiting the USAF museum
at Wright-Patterson AFB. (Dayton, OH) No doubt plenty o' safety wire
to be found under the stealth covers:

NOTE: It was pretty dark inside overall, with strategic spot lighting that made for dramatic displays.
Fortunately I had purchased a sturdy tripod on the way in that day, for I really wanted to
close down the aperture in order to get the largest depth of field of possible.
Camera on stand, Aperture Priority, focus, set the flash on timer...step back,
and wait...and wait...and wait.

The shutter must have been open for 10+ seconds? I was stoked when the
photo came out as I'd hoped it would.

****

Anyway, if you find yourself anywhere near Dayton in your travels, and
you find airplanes interesting, then the (free) USAF museum is well worth
adding to your bucket list.

It was the -60. They could provide the three-phase AC or the bleed air. The later -95s could only provide bleed air. I believe you're thinking of the whole model number. A/M32-60.

RE: My previous entry #61 --

Rereading that today my first thought is that I need to impose some sort
of late-night posting curfew on myself. In my excitement of seeing my old
partner in crime stuffed into the back of my friend's truck I'm afraid that
I may have painted myself as some sort of crazed hoonigan while at the same time
stretching the limits of credulity.

In today's environment where anyone can buy (or steal) a 700+ hp Hellcat &
be a genuine threat to those around them, my fevered description sounds
like pure antisocialism. (!)

****

Now for some proper context. The VW Rabbit GTI in my story boasted a full
74hp & 94ft-lbs powering a 2200-lb subcompact. (~30 lbs/hp)

Meanwhile, the Fiesta weighed in at 1835-lb, with a 66hp/82 ft-lbs under the
hood. (~28 lbs/hp) Here's a link to a test article from the period.

And when I described how I modded the engine with the good bits from
europe, I got that 98ci motor hot-rodded all the way up, to, maybe 90hp.
So that was good enuf to improve the power/weight ratio down to ~20 lbs/hp.

The resulting Fiesta wasn't fast. But it was quick. I used to refer to these
as a very poor man's Lotus Europa. :0) And this managed to move the
car from the 'gotta drive' to 'get to drive' category. Which was a good thing,
for after the twins arrived the 5.0/5-speed Mustang was sold (in order to
buy my 1st house) ...and it looked like it was going to be a couple of decades
of driving the cheapest bottom of the barrel rides until the girls were off on
their own.
So, after discovering the go-cart called Fiesta during a business trip to Galway
Ireland, I came home & found one that had developed electrical gremlins that
the local Ford dealership couldn't sort out. The price of admission per the
seller? $450 with the new radio. $250 without.

"Sold for $250!" I replied. And after a few feverish evenings with the BAT
catalog I managed to brew up a Decompression Chamber for a New Dad
of Twins.

Hope that clears things up a bit. Today? I drive like an old dude. My goal
is that I drive in such a way that nobody even notices that I'm on the road.

I proactively deconflict with those preoccupied with texting while driving.

...but participating in the Silver State Classic is still on my bucket list.
Just gotta figure out which project will get me there before it's time to
check out. :0)

Cheers --

PS: I first read this article a long time ago, but it still gets the
juices flowing today: Big Red runs the Silver State Classic.
(no mods required 'Touring Class' -- I think that 90 miles
just over the ton would put on a good show & a fun video
to be remembered by. :0)

I learned a long time ago that no matter how fast you are...there
is always someone faster. But if I could prove that this old
work truck drove out there, brought some speed-rated tires along
in the bed, swap them on & then run the ton for 90 straight miles...and
then propelled itself back across country to Salt City...I'd be happy with that.

Underpromise & Overdeliver. Give that flowbench a reason for being.
Force myself to figure out all kinds of stuff, including Cd, driveshaft
critical speed > tire diameter & gearing to stay underneath that, MPG
at WOT etc., etc.

Unless I win the lottery, there's a slim-to-none chance that this will happen
in the real world. But it's a lot more fun to think about this as
opposed to, say, how am I going to get more underbody area
covered in POR-15.

Same as it ever was. Burt Munro is my hero.

Snap-On appears to sell the same unit, as WTSTC323, although they don't specify nose length.

The snapon tool is what we use in the army. In fact all of our tools are snapon or bluepoint (same thing). Guess we get a little spoiled on tools.

I can buy a lot of 020, 032, 040 stainless wire, safety wire pliers, for the price of that tool. The replacement wire ends are pricey also.
I believe in an Overhaul facility whereas safety wired and sealed , hydraulic pumps, generator's, csd, fuel controls, and company buys owns them. Sure.
The case was made for a tool that would tension and cut zip ties also. I'm sure it was $200 plus also. But did not last, wear issues , tension slip, leaving a sharp point instead of flush cut. Whereas in a facility that builds wire harness that tool could be standard issue. That didn't mean all ideas bad, some just don't survive certain environments.
