Yeah, but he keeps stomping his left foot on the floor where the clutch pedal is SUPPOSED to be every time he come up to a light or stop sign.

Yup, really, how much extra would it cost to have the various panel appliques made up in the language for where the car is delivered? Some of these stalks by the steering wheel have so many functions now, there's up-down, pull-push, press the end, turn the end, little slider switches, and on and on... Jon |

I are an engineer (of sorts). All my vehicles have had stick shifts since about 1970. In the past, it was because stick shifts got better gas mileage, and were cheaper. I even converted one old vehicle from automatic to manual (because the junk yard wanted less for the manual than a rebuild would have cost me for the automatic). Today, it's purely psychological and maybe a little macho. It doesn't feel like I'm driving the vehicle unless I control the gearing. Having it done automatically makes me feel more like I'm a passenger than a driver. After price, a manual transmission was a mandatory requirement for my last vehicle. I even overpaid the dealer for it as I knew they were getting scarce and difficult to find. And yes, I have problems driving an automatic, try to shift in an automatic, and find my left foot wandering around looking for the clutch pedal. I don't know how I'll do with a self-driving car.

(It had 200 or so miles on it--it had got caught up in the Takata airbag mess, so the dealer couldn't sell it for ages.) Got a nice discount too--it wound up being the price of my daughter's Kia econobox. :) Newer cars are full of surveillance devices, which I cordially dislike.

Well, adding more gear ratios and the lock-up torque converter helped the mileage a bit. Now, I have a hybrid that has a continuously variable transmission and no torque converter. They use a wet-pack clutch like on a motorcycle to do the initial start. So, it has all the advantages of a stick shift, but my family can drive it, too. Jon |

While attending college, I lived for a time in a large old house aptly named "the fire trap". I could hear termites chewing away in the walls. About 3 years after graduating, I returned to visit the school, and drove by house. It looked much the same as when I lived there. The next day, on my way out of town, I drove by again and found that the house had collapsed in a heap. No wall was left standing. According to the news, it had fallen down by itself and without warning, injuring a few students in the process. It's much like the medieval cathedrals, bridges, and other structures, where the failure of one tiny arch, will cause the entire structure to collapse. In a previous life, I tried to design a "warranty timer" into a product. Actually, it was suppose to accumulate and display the amount of time that the unit had been powered on to help establish maintenance intervals. In previous products, a mechanical counter-timer was used, but for this version, it was deemed too big and expensive. <http://www.alliedelec.com/images/products/Small/70132720.jpg> I found a company that made an electrochemical equivalent. It was housed in a glass cylinder, similar to a common 3AG glass fuse. Inside was some chemical solution. When a few volts of DC was applied, electrolytic action caused one end to slowly turn dark, thus indicating the amount of time that the DC was applied. Sorry, but I couldn't find the vendor or an equivalent online. When the required maintenance was performed, the indicator would be replaced as it could not be reset. During the design phase, I liked to joke about installing a 2nd timer in the product, which would blow it up after a specified operating life. I even designed a place for it on one of PCB's. I stopped joking after I found that management was taking me seriously and discussing such things was how to handle extended warranties. The device was later removed in a cost reduction exercise, but the component outline remained in the printed manual, resulting in numerous embarrassing questions because someone had labeled the part as a "warranty timer". -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Heck of a job! You probably don't know this, but it's not a *real clock*. It's one of those cardboard affairs that we used to teach our children how to tell time. Some snowflakes have one that they labelled "Doomsday" on it in crayon and they move the hands one way or the other depending on how *they* feel about things. If there were no Muslims and Communists, this would be a pretty peaceful world actually. And speaking of Communists, it was lovely of the outgoing U.S. president to throw the cold war back decades before he left. That's a heck of a job! |

But the reason to replace them ALL is that if you only replace the one(s) causing a problem, another will fail later, then another still later. It is much easier to do them all at once than to have to repair the same unit over and over as they fail one after another.

Waxed paper capacitors are notorious for moisture absorbtion and becoming leaky. There are plenty of other types of dry capacitors that don't last forever in the high temperature around tubes. |

I've seen loads of ceramic caps fail - but mostly in TV horizontal scan sections where the frequency is over 15kHz and high voltage pulse conditions. This got worse with ever increasing PC monitor resolutions. AFAICR; mica caps were pretty reliable - in most of the places I found them, they were used for precision and a specific tempco. |

I believe in replacing most all the components that are similar when one fails in older equipment. I worked at a large plant and when a 200 HP motor speed control went bad a factory man was called in. He found two power diodes bad. As this was a 3 phase motor and had one more, I asked him to replace it. He told me they were about $ 100 each. I said go ahead. The down time was costing us much more than that an hour,and to get him back in would cost a lot more if the 3 rd one failed, it would be just good insurance. The diode may or may not have been weakened in some way. $ 100 is a small part of over $ 50,000 or more. |

Heck of a job! Yes, precisely why I feel WW3 is a lot closer and more likely than before. This has nothing to do with my own political party preferences, or anything else, just the "person" himself (president). However, lets NOT get into a political discussion on here. Seems like everywhere on the internet has turned to politics lately. But I still do not feel safe, with the current state of the world and the current US president. It seemed a lot safer before, even though the world in general seems a lot worse than it was in the last few decades. |

Huh? You lost me. Yes, I know what the word parallel means, but what do mean? On the primary side, I use the 240 lugs, and connect them to a power cord. On the secondary side I connect the 240 lugs to an outlet. That's really all there is to it, (not including any fuses or switches I might include). -- As far as this project, I have abandoned it, due to learning from the replies, that the output current would be halved, from 750va to 375va. I need a supply which outputs at least 500va. I have an isolation transformer with a 100va output. It works ok for the "American Five" (five tube) hot chassis radios, but I want something with more current for larger amperage needs. I saw this transformer on ebay and thought it would work. I did not know that the current would be halved, which is why I asked abotu this, before buying it. I'll have to just keep watching ebay for something more suitable that is affordable. My other thought is to wire a 240v outlet to my bench and use some of the 240 to 120 v transformers on ebay that sell for small dollars compared to the 120 to 120 transformers. But the problem with that, is that I often work on stuff away from my bench, and then I would not be able to use it. I dont need it tomorrow, so I'll just keep watching for something more affordable that will give me the power I need. Either way, I'm sure I'll end up buying a transformer and making my own isolation device. The commercial ones are very costly, especially the ones that output above 250va. I already have plenty of power cords, outlets and enclosures to make one. And wiring it up is about as simple as any project can be. Thanks to all who helped! |
etpm@whidbey.com: Feb 03 10:01AM -0800 Hey All, I have an old Baldor bench grinder. Probably 70 years old or older. The motor is the type that uses a capacitor for starting and running. There is no centrifugal starting switch. I know this type of phase making scheme provides lower torque for starting so that the motor takes longer to come up to speed. But this grinder takes 5 seconds to reach operating speed, 3400 rpm. I replaced the bearings in the motor and it now spins very easily. There is a 3/4 wide 6 inch grinding wheel on one side and a light weight 6 inch diamond wheel on the other side. The cap in the thing might be the original cap. It is a large round tinned metal can with solder lugs. 330 volts and 400mfd. Could it be that it needs a new cap? I don't know what kind of cap it is. Oil filled I imagine but from the high mfd campared to all my other run caps could it be an electrolytic cap? There is no sign of leaking and there are two places on the top of the cap where it looks like holes were sealed with solder. Thanks, Eric |

But, typically, such a capacitor provides the initial *OOMPH* to get the initial turn on the motor, after which it more-or-less goes away. If the motor starts without difficultly, even if it takes a while to spool up, the cap's work is done in the first few second or so. If you do replace it, DO NOT use a conventional DC cap, even two caps back-to-back. Non-Polarized does not equal AC rated. This may also be a Motor-Run capacitor, but in that case, there should be two, a START and a RUN. Runs are almost never electrolytic types. Again, it must be AC rated. Note: If a start cap, the motor will not start without it. If a run cap, as it weakens, the motor will run improperly or not make speed at all. And if not there, the motor will not start at all as the cap is required to "rotate the field". Peter Wieck Melrose Park, PA |

It always stays in circuit and is a compromise between the proper phase shift for starting and for running. If it gets replaced it will be with an AC rated cap. I'll make sure to get a motor run cap too. Thanks, Eric |

My other two Baldor grinders spin up to full speed in 2 seconds. These grinders don't have a centrifugal starting switch either so I assume they are wired just like my older grinder. I'm concerned the long starting time might lead to overheating the windings after many starts. Eric |
