What's Yours?

Now't very exciting...
Most prestigious thing would be testing the Secondary Radar Systems for Gatwick Stansted and a few other airports in UK many moons ago.
Most glamorous current product would be Urinal Dosing.

(... most fun hobby thing was my Chinese Repeating Crossbow)

Biggest: a computer controlled lifting-weighing equipment for off shore modules weight up to 4.000 To(metric). Weighing uncertainty 0.1% of weight.

Smallest: a pre-load sensor for M3 bolts

Fastest: a temperature sensor with a time constant of 0.3 ...0.6 ms

Among others.

Most spectacular - control system for a waterjet cutter slicing 200 x 200mm chunks (samples) from the 150mm thick steel reactor vessel on a (decommissioned!) nuclear sub. Click of a mouse (MY mouse!), & it went through like a hot knife through butter.

My biggest item was a drawing for an overhead crane system involving dozens of cranes on about a half dozen tracks. The biggest individual crane I remember was about 80 tons on another project.

My smallest item, and the most significant, is a casing I did for a product for the military. The project is classified, so I can't say more. Well, I could, as the joke goes, but then I'd have to kill you.

Slowest and most current... Laser installation, waiting for building contractor to release the building.

Luckily, I'm doing it in a warm place, South East Asia. The food ain't bad either.

Er, how does one weigh a sewage treatment works?

I suppose my fastest was working on the 'Milan' antitank missile firepost electronics.

Slowest is a project that is on-going and has taken 3 years so far for an Irish company, still waiting for their final specifications.... *z-z-z-z-z--zz*

Smallest would be measuring tiny gas jets and medical needle sets for the correct hole sizes approx. 0.1mm diameter.

Largest would be the design and manufacture of a medical instrument which is used worldwide in hospitals.

Most dramatic would be test firing a 'Milan' antitank missile and after 30 feet the fuse was armed then the wire broke and the missile went nuts as we all dived into a muddy trench!! Luckily the missile only hit an army generator costing about £10,000, made a right mess of it though!!

biggest - a 1,000,000 Watt AM transmitter - you could walk inside it (when it was turned off).

smallest - postage stamp sized phased radar transceiver

fastest - U2 spyplane, unless you count the Orion spacecraft

slowest - extremely low frequency (ELF) comm system for submarines ~ 55 Hz

lightest - current CEV docking system project - in the sense of weight being an important design requirement.

heaviest - I've design several "boat anchors" in my time.

Biggest, reactor vessel installation at a Nuclear power station. Amazingly large crane..

(Second biggest was doing an inspection on a slant axis hydroturbine. Stand on the blade looking for cavitation damage, imagine a ships propeller with an 100 foot diameter..)

Smallest, I am from Texas, we only do big....

Fastest, turbo expander on a air seperation plant at 40,000 rpm.

Slowest, output shaft speed on a gear extruder, at about 2 rpm.

Heaviest, probably the main turbine generator set on a 1000 MW nuclear plant. Or an off shore oil production platform, if you want to call that one piece of kit.

Lightest, I don't mess with light either..

Smallest: Hearing aid.

Most "glamourous": Automatic toilet/urinal flusher.

Most critical: Safety system response time measuring system for a nuclear power plant.

Most deadly: Process control for baking Gen 3 image tubes for night vision goggles (so people can kill people better in the dark, what else?).

Or perhaps it was the coil winder for TWT's in aircraft radar...

Greenest: Energy management systems for the hotel/motel industry.

Quietest: Audiometer for testing hearing.

Most precise: Machine control for cutting high security lock keys to +/- 0.0001" tolerance in a production environment.

I once steered a 260,000 ton oil tanker through the Persian Gulf, a 27,000 ton cargo ship through the Panama Canal, all this just to gain my steering certificate for the MN.

Spencer.

Since we demolished our larger machine (.95 miles long ) I'd have to go with our recent overhaul for this little puppy only about 1500 feet long. This is the drive unit.

that's a big taffy puller.

"taffy puller" - language problem - please explain .

[Sorry - neglected to tick the "off topic" box (again). One of my few big CR4 gripes is "why can't I mark my own post OT after posting it?"]

I have a big wood chipper 110" disc 20 thousand pound flywheel total weight spinning 50,000 pounds will chip a 27" in logs surprisingly it spins at 350 rpm original hp 2000 electric ( converted to diesel ) we nicknamed it the collider a fun machine to watch atomize huge chunks of wood

Replacing the top of a cat cracker complete with cyclones. 2000 Tons.

Steam generator replacements. 200 tons to 400 tons.

Smallest- fusion splicing polarization-maintaining optical fiber.

largest- Engine room, USS Ranger (Forestal Class Aircraft Carrier).

Fastest- Casini Prope

Slowest- My perpetual motion machine invention (mentioned in other posts, which most people mistake for a rock sitting on a park bench).

Most exciting- I haven't gotten there yet, but I'm working on it.

Hi,

The largest I worked on was a Skiaci? spot welder that was about 12 feet long, 6 feet high and 3 to 4 feet wide. It had 2 large mercury rectifier vacuum tubes, and a large thyratron tube, each with metal caps on top. It would throw sparks for at least 5 feet when welding. The slowest was a digital computer with a teletype to load the executive program with a paper tape. That took 35 minutes.

Smallest - high gain mic pre-amps

Largest - 50kA electro-plater supply, the cabling is a bit heavier than for mics!
