Can odd parts be bought through Caswell individually

Just build a faraday cage around your electronics. Then, when all others are living in caves, we can run our subs at the lake and be part of the circus. -
We are one significant EMP event away from savagery. Man made or natural, cause matters little in the end.

I cant tell you how many times I have called a vendor for a part and their reply is: "Im sorry, our computers are down, when they come back up we can then tell you how much they are and if we even have one. Call back later.
When I was a kid, I remember being in the USave supermarket when a storm hit and the power went out. If that happened today they would be crippled. Back then the "Bag Boys" went over to the cash register and inserted a crank handle into the side of the machine. The girl would hit the price buttons, the boy would turn the crank, wallah, next item.Leave a comment:

Remember when we ruled the technology? Now, we are enslaved by it. The Caves beckon!
All power to the Hypno-Toad!

Good point. However, on this particular Beast its all or nothing. All the computers must work together or the Transmission wont engage and the brakes stay locked. Each computer is about $3500 and requires programing on site using proprietary software and Hardware. There is only one vendor in Tampa that is an authorized service center and their booked for a week at a time. I dont know Andy how it is in the UK but over here I have yet to see a computer tell on itself as being faulty. The codes that they send to troubleshoot with are usually vague and send you on a wild goose chase. Ive never seen a code for a bad computer.Leave a comment:

There's a fairly long computer chain in these systems too, although a lot of redundancy is factored in, so should one computer start to throw a fit, another can step into its place.
Worth bearing in mind that even in out little model submarines, we tend to have half a dozen computers in the form of micro controllers all doing their thing- one in each servo (unless they're very old analogue models), one in the receiver (again unless it's pretty old) one in a leveller, one in an ESC, and another in the TX. They all work fairly reliably don't they? Infact so reliably it's inevitably a discrete that takes out something else e.g. a transistor or capacitor.
The main problem with these modern systems is when they go down, they tend to go down very hard e.g. when you get a control system failure you tend to lose half or the whole railway, with the older system, you would reduce your service, but you could still keep the wheels turning.Leave a comment:

Why do we need a computer to control the Allison transmission? Its not like it has a thousand functions or something. Next thing ya know theyll say that we need a computer to control the windshield wipers. I mean , do they have stock in Gateway or IBM and they have all these computers taking up space on a shelf somewhere and they are desperate to find somewhere to put them??
I think that all these guys get all these student loans to go to college with to learn how to be STUPID!!!Very AngryLast edited by greenman407; 09-07-2013, 08:11 AM.Leave a comment:

We have a Forklift(Kalmar) that uses four(4) computers. They all have to be in sinc to allow the machine to move. One computer is for the Transmission. I ask you. What kind of an IDIOT would strap not one but FOUR computers on to a vibrating, hot,shaking , bouncing(rough terrain)piece of heavy equipment and expect that its going to work??? Uh...DUH!!!Leave a comment:

We have a few 'switcheroo' standards on our job. Much of the older legacy equipment is in imperial measurement, the later kit is metric. The brand new stuff they are plugging in mean I will now have to cart around an oscilloscope, and hand held computer, because we need them for diagnostics, as the signalling systems are now comms and computer based rather than electro mechanical. Brave new world.Leave a comment:

We have the same problem making Hydraulic hoses for all this Heavy Equipment out here from all manner of manufactures. First of all you have NPTF(national pipe thread fuel), NPSM swivel thread, JIC 37 degree,SAE 45 degree, SAE Oring, Flat Face, Inverted Flare, Compression Thread, Code 61, Code 62, BSPP(British Standard Pipe parallel), BSPT(British Standard Pipe Taper), Japanese Pipe tapered, Air Brake Thread. Then to boot you have the 5 major Metric threads: Witworth, MDL, MDH, Komatsu, French. Then of course Caterpillar has their own as well. OMG!!!Give him a soapbox!
P.S. After I wrote this I thought of a few othersLast edited by greenman407; 09-06-2013, 06:49 PM.Leave a comment:

You'd appreciate my son's business www.britishfasteners.com with BA BSF BSW ME BSC and BSP threads and tools! Right here in America too!Leave a comment:

Surprised you got metric kit from the UK in the '60's, don't think we really started to seriously convert until the 1970's. When I was in technical college back in the late '80's I still had to produce about 35-40% my work to imperial tolerances and measurement, even though the machines were calibrated in metric.Leave a comment:

I used to own a 1984 mini 1000, that had a mixture of metric and imperial fittings (as built by the factory BTW), so I used to have to wheel out both my metric and imperial toolsets when working on the little rascal. That car was the spawn of satan. An earlier 1978 car was a lot easier to work on, being all one standard.

I'll go metric the day they pry my old-school (battery not required!), fractional micrometer from my cold, dead hand!
