We had sold a Sodick EDM to them and we had to fly out to do a repait -- two young Japanese guys from our staff, one an engineer and the other a technician, and me (Marketing Manager). But they make (or made) nuclear-bomb triggers there and the Japanese couldn't get past the lobby. So they sent me in with some test equipment and got on the phone with me. We had a box of discrete parts and the boards with us that we thought were the problem, but that wasn't it. So I had to solder a couple of components right on the shop floor. Fortunately, they were through-hole, two-side boards, not multi-layer. -- Ed Huntress (KC2NZT) At Mitre my machine shop was secured behind a cypher lock yet the Ph.Ds still got in to try to cut lawnmower blades on the bandsaw, at the wood speed. However I could leave my soldering station out and the lab door unlocked, certain that none of them would dare risk using it. Instead they'd leave the job on the bench with a little note. Like tying climbing knots and 7018 rod it becomes very easy with practice. -jsw |

... It's not just a mindset. I would love to be able to reliably design simple solutions to simple problems. I can't, easily. I can COPY someone's simple solution to a problem, I can, eventually, figure out simplifications to some complex solution that I (or someone else) has come up with, but a dirt-simple solution that actually works often evades me. Fortunately, there are plenty of Really Complex problems out there just crying out to be solved, and that I can do. Tim Wescott Wescott Design Services http://www.wescottdesign.com Sometimes it helps to jump the wall and look elsewhere. It may not be original, but I ran a simple A/D converter from an LPT port by sending "print" data to an attached 8-bit DAC and reading back a comparator connected to the DAC output and the signal. The 8 data lines were also connected to other stuff that I ignored during a conversion, and vice versa. -jsw |

While I don't fix anything related to cars, they do seem obnoxously designed with all sorts of pegs and covers that have to be broken apart to get to anything. Hell, even headlamp changes require a tear down and small hands. |

You start by defining the requirements, or rather debating them until Actual requirements are usually really hard to come by. you're too tired to argue, then distribute the work among your personnel, come up with a separate solution to each requirement, prototype and test them individually and then together, and finally try to combine the elements that seem to need no further redesign to serve multiple functions and reduce tooling, fabrication and assembly cost while management pesters you to release it to production NOW to beat the competition to market. They are obsessed with the name recognition and sales momentum that comes with being first, and know that the engineers would love to keep playing with it.

There's no sign of any modules of grouped functionality or subassemblies that are not interconnected in 3 dimensions with 15 other parts. That's why I wonder if labor was free when thing thing came off the assembly line. Even assembling it would have taken ages. I recall some VCRs that were never designed to be serviced. Replacing one tire involved actually cutting a hole the stamped metal made up the transport. Sanyo eventually woke up and redesigned it enlarged openings where people were previously cutting holes. Stupid design. |

Cydrome Leader fired this volley in news:lvq5ev
: Stupid design. Only stupid in retrospect. They did not anticipate the need when they designed it. You're a mook, CL. Smashing an F-body camera just to complain about the complexity of it is ridiculous. Even lacking the prism, it was valuable to someone other than you. They were complex because of how much they could do -- mechanically, only. Despite their complexity, they were marvelously reliable. Even many that got dropped and/or banged around in service continued to work just fine. I have a 1948 Meteor SP (1/2-frame 35) rotary focal plane shutter camera that's a lot simpler than a Nikon-F, if you really want 'simple'. My old Asai Pentax is every bit as complex as a Nikon. Despite its 1980s origins, it's as reliable today as the day it was built. Film... that's another problem. Only one maker still out there... LLoyd |

If they don't know what they want then you have a chance to tell them. We've acquired some really great airplanes that way. http://en.wikipedia.org/wiki/Lockheed_P-38_Lightning "Kelsey recalled in 1977 that he and Saville drew up the specification using the word interceptor as a way to bypass the inflexible Army Air Corps requirement for pursuit aircraft to carry no more than 500 lb (227 kg) of armament including ammunition, as well as the restriction of single-seat aircraft to one engine. Kelsey was looking for a minimum of 1,000 lb (454 kg) of armament. Kelsey and Saville aimed to get a more capable fighter, better at dog-fighting and at high-altitude combat." -jsw |

The original F camera was one expensive *******. https://www.cameraquest.com/fhistory.htm ".....Strangely enough the March 1959 Philadelphia photo show saw the US introduction of three new top brand Japanese SLR lines: the Minolta SR-2 with 55/1.8 and a list price of $249.50, the Canon Canonflex with 50/2 and a list price of $299.95, and the Nikon F with a 50/2 had a list price of 359.50. The Nikon F completely eclipsed everything else in its time as a Pro 35. Professionals switched from the Leica M's (and everything else) to Nikon F's in legions, and to this day Leica has never recovered. But more than the Professional's switch from Leica to Nikon, it also signaled the maturity of the Japanese photo industry. From that time on, Japan was the new Photographic Industry leader and Germany would be doomed to play catch up. Zeiss got out of the camera business. Rollei hangs on bought out by Samsung. Leica continues its post Leitz family experience once having been owned by a concrete manufacturer and now has new ties to Yashica. The Nikon F was a really big deal, a crucial turning point in 35mm Photography." http://www.dollartimes.com/inflation...=350&year=1915 That came out to...wait for it... $2,822.39 in 2014 money With cash discounting...Call it $2500 today.

Ive got at least 40 35mm cameras and a host of others in other formats that I dig out every 6 months or so to wind, trip and work through the speed ranges to keep em limber and working...and a good sized box of film in the freezer. Mixed 35mm/120/220 and a few rolls of 680 that are nearly as old as my 35 yr old son. On the top of my desk is a Canon AE-1 with a 70-250 Canon lens on it that I loaded 6 months ago and am just about at the end of the roll. Been using it for wildlife and "fun" photos of neighbors and passer-bys. The (2) Canon A-1s are loaded and I put fresh batteries in them 5 months ago..those are my most "high tech" film cameras..and I think there is a half roll in the Hassey. Need to start thinking about where to find some more film. dont I? The Oly digitals have taken over most of the photo load of course..but I simply have to get prints in my hands now and then...(Grin) Gunner "At the core of liberalism is the spoiled child, miserable, as all spoiled children are, unsatisfied, demanding, ill-disciplined, despotic and useless.

Simmon-Omega D2 enlarger with the condensor color head, polycontrast filter set, the whole thing. Gunner, stuff comes, and stuff goes. To be honest, a high-end pro- digital can do anything and all things film could, except for manipulation in the darkroom. And that was "once or nothing", at least with the film, itself... like 'pushing' a roll, or cold-processing for higher contrast. At least with digital, if you goof, you can try it again. Screw up a roll of film, and you went out and shot it again. Lloyd |

I reduced the complexity of two of their other persistent problems by half by substituting simple but subtle mechanics for complex electronics and probably earned more resentment than gratitude for it, though they did move me from lab tech to design engineer. Kudos. The electronic and mechanical engineers at that and several other places I've worked knew little of each others' discipline and didn't cooperate very well when it meant subordinating themselves to each other instead of being in charge. I'm fairly competent at both so often they dumped the problem on me, and I had to be very diplomatic to stay on everyones' good side, or at least not be the person they hated most. That's cool. I envy your vast knowledge/experience base. (I only made it to half vast.) Had I wanted to go to college, I likely would have taken both electrical and mechanical engineering courses.

It's still stupid design if nobody though ahead at all. You're a mook, CL. Smashing an F-body camera just to complain about the complexity of it is ridiculous. Even lacking the prism, it was valuable to someone other than you. A F is not rare or valuable, no matter what you tell yourself, they churned out trillions of the things. Check prices on keh.com They were complex because of how much they could do -- mechanically, only. Despite their complexity, they were marvelously reliable. Even many that got dropped and/or banged around in service continued to work just fine. I have a 1948 Meteor SP (1/2-frame 35) rotary focal plane shutter camera that's a lot simpler than a Nikon-F, if you really want 'simple'. My old Asai Pentax is every bit as complex as a Nikon. Despite its 1980s origins, it's as reliable today as the day it was built. Film... that's another problem. Only one maker still out there... not true. |

Sigh, the whole "if all you know is the hammer, everything is a nail." At my first job after the Army I told them I'd like to work my way up to engineer, so they ran me through all the departments to learn the intricacies of custom machine design and fabrication. That was really cool of that company, Jim. I doubt it would happen at 99% of places nowadays. I'd learned mechanical drawing in jr high and Statics and the properties of metals Statics or statistics? I had all the tech classes in early school, too. Metal and wood shops, basic aviation, HS organic chemistry, mech dwg. in college, which were big helps. I didn't actually operate a Bridgeport, TIG welder or press brake but I learned what they can and can't do. Reality sets in once you do get onto a machine. Theory and paperwork only get you so far. Then it takes a bit of time converting those old synapses from concept into manual dexterity. It can be shocking, but it's fun, most of the time, right? All knowledge is good. I did drill and tap a lot of holes and learn to bend sheet metal accurately on a manual brake. Great. I finally got back on my little HF (Harbor Freight, not high freq) TIG yesterday and once again repaired the steel mount bracket for Dad's old Craftsman circular saw. I hadn't penetrated well enough the first time and it only lasted two months of very light work. This time, I turned the amperage down and spent some time pooling the area so I got a good, deep puddle. What I didn't burn through the first time looks, um, fairly good now. (no picture requests, please Anyway, the more metalworking, plasma cutting, and TIG welding I do, the more I like it. I wonder what kind of solar/battery setup I'll need to continue to use that thing once the grid goes down... Time to start looking at 240v inverters, I guess. -- One word frees us of all the weight and pain of life: That word is love. -- Sophocles |

B-) Nowadays, we have modules which are plug and play, do multiple functions, and can't really be repaired. Not cost effectively, compared to removing and replacing. -- pyotr filipivich That started in the 1980's with surface-mount electronics, which are substantially more difficult to repair by hand than thru-hole, and not reliable unless the tech who solders on the new parts is more than usually skilled and experienced. I got the experience on lab prototypes where a solder failure was only a brief inconvenience instead of costing a field service call. I didn't stay in the field long enough to get that kind of experience. Compared to thru-hole SMT is very cheap to manufacture, costing little more to make than the Bill of Materials, and the ICs themselves are cheaper to make due to the smaller lead frame with much less metal. I first encountered the no-repair policy on computer add-in cards for Winchester drives, when the vendor didn't want us to return defective ones. The Army taught us troubleshooting to the transistor level. They had so much difficulty finding recruits who could learn it that they changed to training LRU (Line-Replaceable Unit) board-swappers. Sad, isn't it? The four (of ~80) of us who graduated all had science degrees. The washouts had a choice of other repair schools so they weren't wasted. My year at Coleman College's Computer Electronics Technology course taught me troubleshooting down to the component level, too. I stayed at it for only 3 years as a test tech before SKF bought out Palomar Technology (vibration datalogging/pre-failure maintenance) and I changed to a computer repair/software guy swapping boards in mainstream personal computers. I've lost, from disuse, most of what I learned at Coleman in 1986-7. A friend just retired from the appliance repair field. He was a natural at troubleshooting beyond the board, but most of his work was board replacement until they learned that he could do more. He ended up getting all the "bad" jobs, where board-replacers couldn't fix the appliance. Lots of these folks are either getting out of the business or dying from old age, so what comes next, when all of the true knowledge is gone? How far away are we from the coming global Idiocracy? I probably have only 10% of the learning of some of you folks here, but most of what I have is practical knowledge. I have a feeling that I'll need all of that (and a whole lot more) in the coming years, waiting for the other shoe to drop. -- One word frees us of all the weight and pain of life: That word is love. -- Sophocles |

I have curiousity to burn. Before it (the lens) goes back for some sort of cam calibration, I wanted to see what was inside. After putting it back together, it seems to line up correctly at infinity again, matching the other lenses that do in fact work correctly woth the same body. It appears the grease is separating into oil though, or they're really heavy handed with "oil barriers" to prevent water from getting sucked into parts. Some of the paint on the light baffles is coming off, which is just silly, so the thing may just go back anyways. I have two Leica rangefinders. One fell into salt water 50 years ago and is completely shot, even though it looks OK. I was offered $300 for that body. But I kept it for my collection. Never taken one of those apart. I have fixed Crown Graphic cameras with the top rangefinder and light beams. Unlike everything foreign, they're simple, easy to fix and don't require gadgety tools to work on. It looks like you need 7 types of spanner wrenches or "split screwdrivers" to properly take apart an F. Not sure why they stopped at that and didn't got for 27 or 39 different types. Why anybody would even want to make, warehouse and then install at least a thousand parts into a camera while adding as many parts as possible for even mundane use. A comparison on the self timers on the F vs some sort of Sears branded 1970s Mamiya shows the F has at least twice as many parts. All it is is a geartrain with a spring and escapement that takes about 10 seconds to hit ero at which point a cam moves something and fires the trigger release. They're actually quite similar is size and construction otherwise, so it's apparent half the Nikon parts simply aren't needed. |

Breaking some thing because you don't understand how it works is not "educational". It's the fast way to see what's holding something together, and if you don't need it put back, it's fine. In fact, taking a hammer to saw to stuff is a good way to learn where the strong and weak points are in something. Its wanton vandalism of the worst sort. Try convincing yourself it is something different...but it simply doesnt wash. Ill bet you would love to smash open one of my Nikon S's. I wouldn't mind. Current value of the "black/black dial" one is $2500.00 That's about 33 times more than an F with no prism. https://www.cameraquest.com/nrfs2bl.htm Rare as hell Complicated inside too! Rangefinder mechanisms can be super complex, although it's not necessary at all. Does the S have different sight lines and parallax correction? |

Nostalgia for fixing and adjusting my S.U. carburetors (carburettors, I guess) on my mother's kitchen table isn't enough to overcome the fact that I had to do *something* with my old cars almost every week. I'd say they are. Even though the purchase cost of autos has gone up vs real income, the _usage_ cost has plummetted. Most cars of the 1960s and early 70s required things like valve jobs every 30K; not a minor cost to someone who could not do the work themselves. Now, it's common to go 200K without a major repair, and only the 'timing belt issue' to deal with in the interim. "Tune-ups"? Phhhfffttt! Thing of the past. A car can easily go 100K without even looking at the plugs. Everything about modern cars works better, is more comfortable, and lasts FAR longer than those of even 40 years ago. They're more efficient with fuel and lubricants, and they're far safer. Some of it was government intervention. Some of it was innovation. To me, all the above are signs of engineering excellence, regardless of how difficult the vehicles might be to work on. Yep. Lloyd -- pyotr filipivich "With Age comes Wisdom.

typed in rec.crafts.metalworking the following: WHY???!!! did you smash a Nikon F body??? They are still worth in excess of $200 each and for us collectors..they are freaking priceless!!! Barbarians - they break what they don't understand. Tearing stuff apart is the greatest way to learn about how things work. Disassembling is one thing. It is called "reverse engineering." Breaking some thing because you don't understand how it works is not "educational". It's the fast way to see what's holding something together, and if you don't need it put back, it's fine. In fact, taking a hammer to saw to stuff is a good way to learn where the strong and weak points are in something. Its wanton vandalism of the worst sort. Try convincing yourself it is something different...but it simply doesnt wash. Ill bet you would love to smash open one of my Nikon S's. Current value of the "black/black dial" one is $2500.00 https://www.cameraquest.com/nrfs2bl.htm Rare as hell Complicated inside too! It came to me that there might be another explanation. Because when I was a kid, the return lever on my dad's typewriter broke, and parts were no longer available. Not even from the factory (we checked). So one afternoon, I being bored, took it apart. Disassembled it pretty completely. Saw no reason to keep the cast iron frame, so broke that up. It wasn't until decades later, that I realized "there probably was a metal shop in the High School, an new part could have been made. Even with 1970 technology." Sigh. So soon old, so late schmart. -- pyotr filipivich "With Age comes Wisdom. Although more often, Age travels alone." |

Pentaprisms can be found -- or waist level finders -- or sports finders -- or ... while I'm typically no fan of destroying stuff like this, it is the only option when no service manuals are available, and you can't hire and old guy to let you watch a repair. The question still stands. When do companies design stuff to be overly complex. What's the real end goal? To make the camera manufacturable. A lot of those parts are for tuning the speeds and motions to allow for variations in spring constants and the like. The cheaper cameras have fewer parts, and less accuracy as a result -- especially as they age. Of course, today a lot of that is tuned using microprocessor chips built into the camera. :-) Service manuals for many Nikon cameras, including the F http://arcticwolfs.net/downloads.php Thank you! I've now downloaded manuals for all the Nikon SLR cameras I have. (Do you know of a similar site for the Zeiss Contax?)

19:50:54 -0700 typed in rec.crafts.metalworking the following: I did drill and tap a lot of holes and learn to bend sheet metal accurately on a manual brake. Great. I finally got back on my little HF (Harbor Freight, not high freq) TIG yesterday and once again repaired the steel mount bracket for Dad's old Craftsman circular saw. I hadn't penetrated well enough the first time and it only lasted two months of very light work. This time, I turned the amperage down and spent some time pooling the area so I got a good, deep puddle. What I didn't burn through the first time looks, um, fairly good now. (no picture requests, please Anyway, the more metalworking, plasma cutting, and TIG welding I do, the more I like it. I wonder what kind of solar/battery setup I'll need to continue to use that thing once the grid goes down... Time to start looking at 240v inverters, I guess.

Simmon-Omega D2 enlarger with the condensor color head, polycontrast filter set, the whole thing. Gunner, stuff comes, and stuff goes. To be honest, a high-end pro- digital can do anything and all things film could, except for manipulation in the darkroom. And that was "once or nothing", at least with the film, itself... like 'pushing' a roll, or cold-processing for higher contrast. At least with digital, if you goof, you can try it again. Screw up a roll of film, and you went out and shot it again. Lloyd As far as enlargers go, I like the Omega Pro Lab, 5 or 6 series, since they're all pretty much the same. They are machines of truly great design. They are sturdy, reliable, use simple parts and are easy to adjust and repair. There are no bull**** extra parts. All the parts that wear out can be replaced with stuff from any hardware store with a good selection of parts bin. The opposite of Omega would be something like Durst. Every part is specialized or complex because they came out of a socialist country with machinists nobody could fire. THe minute a product has dozens of types of fasteners, you know the rest of the product is going to be just as stupid. In the late 1980s and early 1990s, Motorola had some truly innovative engineers who made some fairly incredible products, like their handheld radio line. I recall some of the Radius series had no screws at all, were easy to assemble and just as easy to take apart. They were also completely weather sealed, which was made even easier as they didn't have any screws to start with. Yes, they were super tough too. Simple is good, and they really ran with this concept for a while. |

You can even carry on conversations with some of them.

Tearing stuff apart is the greatest way to learn about how things work. I was just thinking about other things that are just overly complex for no reason and remembered server rail kits from Sun and especially the ones from Sun designed by Fujitsu. They're supposed to just be rails that allow a server to slide in and out of a 19" rack. Pretty simple, like glides for a desk drawer. HP has it figured out, Dell took years too, and almost got it right, but not Sun/Oracle/Fujitsu. I've still never figured out what all the extra pieces are for, even with the installation book, and I've not come across anybody else that has either. As to why rails need to be highly asymmetrical from left to right is mind boggling. Even with ball bearings, they're harder to operate than metal on metal sliders, are prone to just falling apart and require special alignment jigs for installation, even into industry standard racks. Plus, with no matter what you do, you're going to get grease all over your hands. Here's a personal message to anybody involved in those products - "you're a complete idiot". Tektronix figured it out in the '50s & '60s. Slide an item out, lift and remove for service. Or lock the rails and rotate the chassis to service it in place. It was a real joy to be able to connect to a piece of equipment from the front of a rack, then slide it into place. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge. |
