Any easy way to delaminate a big transformer
I have a couple of water cooled low voltage high current transformers
like these: https://lh3.googleusercontent.com/-d...726_131901.jpg They are not the usual kind and have very heavy copper bars and pipes for windings and cooling. I want to know how I can delaminate them in an environmentally conscious fashion. Thanks i |

: I want to know how I can delaminate them in an environmentally conscious fashion. Thanks I'm not sure what you mean by "delaminate". What advantage - for scrap value - would de-laminating the laminations have? If you want to just salvage the copper separate from the iron cores, do what we did when we were rebuilding them at Florida Transformer Corp... just saw off the coils flush with both sides of the core, and pull out the copper in the openings. Hammer out whatever is fixed into the openings by varnish. It's a big job to rebuild one by hand (especially considering the floor space it requires, since you must hand-pull the new coils through, instead of bobbin-winding them), but it's only a few minutes work to extract the old copper from the core. There's no method I know of that will effectively dissolve the vacuum- potted varnish out from in-between the lams. LLoyd |

I am open to great ideas, if someone knows how I can use my press to separate the transformer, I would be delighted. The press is genuinely double acting and can be used for pulling -- bt the pulling force is a lot less than the pushing force. i |

: Shear off the winding down the metal core. both, both sides. Pound out the windings. Martin, that's what I already described to him. Back in the late '60s, it was still economical to rebuild those big ones, without delaminating the core. That meant sawing out the old windings, then re-winding them in place, using at most a hand-held bobbin, and sometimes just a parking lot with room enough to swing the free ends of larger square wire while bending it place with a leather mallet. But the start was always the same. Saw off the coils flush with the core, and beat out the material that was stuck with Hi-Sol Varnish. Lloyd |

: OK, how do you saw it on a transformer so big. A recip saw with long demolition blades should reach everything. It looked to me like there wasn't any portion of the coils further than about 8-10" from the outside edges of the core stack. Besides, those long recip blades are flexible. You don't have to be perfectly parallel to the core to do the sawing. Lloyd |

We had a gas furnace that we would set a bunch of motors in and bake them so the windings would come out easy. After they were rewound and varnish dipped, we would bake them again, in a different oven, not as hot. Mikek |

I have a feeling that iggy is doing just fine for himself. He could even be that secret millionaire living next door. MikeK, I appreciate your sentiment, but I want to say something about millionaires. Being a millionaire used to mean a lot. Say, 100 years ago, millionaires were very rare, and a million dollars was significant wealth, enabling the lucky millionaire to live an extravagant, enviable lifestyle. That rarified millionaire lifestyle 100 years ago, accidentally, was worse than the life that a regular middle class person earning 100k/year enjoys nowadays. They did not have air conditioners, cell phones, the Internet, comfortable cars, Viagra, TV, modern medical care, modern airplanes, and many other things. So, I would much rather earn 100k per year today, than be transported 100 years back and given a million dollars to play with. Today, in terms of social standing in the wealth percentile distribution, a million dollars in 1914, would be an equivalent of, perhaps, 50-100 million dollars in 2014 money. A million dollars nowadays, is a very boring sum of money, unless you are willing to blow it and spend it all in a few months. You can only derive $40,000 or so of income per year without endangering the principal. This would not give you any ability to live extravagantly. A million dollar home, in most areas, is a very nice, but not remarkable house. Etc. A million dollars still sounds like a lot of money to a lot of people, but practically this is no longer the case to those who think about this in practical terms. What is still true, however, is the saying that "the first million is the hardest". A million dollars is a sum that allows one to open business ventures without being hobbled by bankers and investors, and to make and compound the money without having to work for someone else. i |

Pretending to be super intelligent, or super knowledgeable about anything, is not something that interests me personally. I have some things that I need done, like how to get copper out of a special transformer, and when I feel that I need to ask, I ask. If this makes me look bad in the eyes of "machining luminaries" like jon banquer and "precision machinist", so be it. There are people out there who build their entire life around pretending to be something, and I try not to be one of them. i |

MikeK, I appreciate your sentiment, but I want to say something about millionaires. Being a millionaire used to mean a lot. Say, 100 years ago, millionaires were very rare, and a million dollars was significant wealth, enabling the lucky millionaire to live an extravagant, enviable lifestyle. That rarified millionaire lifestyle 100 years ago, accidentally, was worse than the life that a regular middle class person earning 100k/year enjoys nowadays. Wow, being a multi-millionaire is good. Cities and counties are easier on those over a million, because they don't want to drive away the investment they bring. Most of all, being at least multi-millionaire allows you to to be fairly above-the-law, too. Don't believe me? Check this out: ================================================== === Texas multimillionaire cross-dresser Robert Durst allegedly exposes self, urinates at CVS drug store by DAVID BOROFF NEW YORK DAILY NEWS Durst 'got his prescription, paid for it, exposed himself, urinated on the register and walked out of the business,' Houston Police Department spokesperson Jodi Silva told the Daily News. AM Texas multimillionaire and cross-dresser Robert Durst, who was acquitted in the dismemberment of an elderly neighbor 12 years ago, exposed himself and urinated on a cash register at a Houston drug store Sunday, authorities say. The incident occured at a CVS, Houston cops said, and there was no dispute, as had been reported. "He got his prescription, paid for it, exposed himself, urinated on the register and walked out of the business," Houston Police Department spokesperson Jodi Silva told the Daily News on Tuesday. "Reports that there may have been an argument were incorrect. There was no argument. He did not seem agitated, he did not argue with anyone. He just casually walked out of the business." Durst, 71, was charged with criminal mischief, a misdemeanor. "I have been notified Mr. Durst was arrested for a Class B disdemeanor and is in the bonding process," his lawyer, Chip Lewis, told ABC 13."He will go through the process like any other citizen of Harris County. We will deal with the case on its merits once he is released from jail." Durst was acquitted in 2002 of the murder of 71-year-old Morris Black, whose body parts were found floating in Galveston Bay. He said he shot Black in self-defense and cut the body up before tossing the pieces into the bay. He was eventually given prison time for evidence tampering and bond jumping, according to the Houston Chronicle. Additionally, he has long been considered a suspect in his wife's 1982 disappearance. Authorities also say he may have been involved in the 2000 murder of journalist Susan Berman, who was a friend of Durst's wife. While living in Texas, he started cross-dressing to avoid authorities. The Durst Organization, a billion-dollar real estate company, declined to comment on his arrest.

Any easy way to delaminate a big transformer
OK, I spent some time thinking about these transformers. One has two
windings and another, has three. I do not think that it is easy to cut them with a saw. (though I can be wrong). Here's what I can try to do. 1. Break the varnish with a bobcat-mounted hydraulic hammer 2. Pull the laminations apart with the double acting press 3. One I have the windings out I will be happy. i |

: 1. Break the varnish with a bobcat-mounted hydraulic hammer 2. Pull the laminations apart with the double acting press 3. One I have the windings out I will be happy. If they're gapped lams that might work. That is, if all the "E" pieces are oriented in one direction, and all the "I" pieces are assembled in one piece, situated on JUST ONE end of the E pieces. And that may be the case with a transformer that had a large DC component flowing with the AC (like if it fed a half-wave rectifier bank). Core gap reduces core losses with high DC components in the current flow. However, the one appears to be a three-phase device. That's almost always a AC apparatus (even if it fed a rectifier, it would likely be a full-wave affair), and the laminations are going to be truly "interleaved" "E"s and "I"s alternating top and bottom. You can't get those apart that way. You CAN saw off the top of the core, then just press the coils off from the other end. A big (BIG) bandsaw would make quick work of that. I keep forgetting you're just scrapping it. It doesn't matter if you cut the core. Nobody's going to salvage it as transformer laminations, anyway. LLoyd |

We're talking about HOW you go about accomplishing it. If they are vacuum-varnished transformers (almost certain), and the laminations are interleaved (very likely), you are NOT going to just "pull apart" the laminations, no matter how big your press. I've done this work (not to salvage, to rebuild). You may get lucky and find that both are gapped cores. I don't think that's likely. Lloyd |

MikeK, I appreciate your sentiment, but I want to say something about millionaires. Being a millionaire used to mean a lot. Say, 100 years ago, millionaires were very rare, and a million dollars was significant wealth, enabling the lucky millionaire to live an extravagant, enviable lifestyle. That rarified millionaire lifestyle 100 years ago, accidentally, was worse than the life that a regular middle class person earning 100k/year enjoys nowadays. They did not have air conditioners, cell phones, the Internet, comfortable cars, Viagra, TV, modern medical care, modern airplanes, and many other things. So, I would much rather earn 100k per year today, than be transported 100 years back and given a million dollars to play with. Today, in terms of social standing in the wealth percentile distribution, a million dollars in 1914, would be an equivalent of, perhaps, 50-100 million dollars in 2014 money. A million dollars nowadays, is a very boring sum of money, unless you are willing to blow it and spend it all in a few months. You can only derive $40,000 or so of income per year without endangering the principal. This would not give you any ability to live extravagantly. A million dollar home, in most areas, is a very nice, but not remarkable house. Etc. A million dollars still sounds like a lot of money to a lot of people, but practically this is no longer the case to those who think about this in practical terms. What is still true, however, is the saying that "the first million is the hardest". A million dollars is a sum that allows one to open business ventures without being hobbled by bankers and investors, and to make and compound the money without having to work for someone else. i Looks like you have paid attention to building a net worth* and what income it will generate. It's true a million dollars ain't what it used to be. But, if you follow the 4% rule and add in a husband and wife's SS, you're looking at $75,000 a year. For me that's more than comfortable. Less than 5% of the population has a net worth over $1.4 Million. Interestingly, 50% of the population has a net worth of under $57,000. Here is an article showing what has happened to wealth in the last 10 years. It has a chart of wealth of American households. http://web.stanford.edu/group/scspi/...lth-levels.pdf Here's where I started to get that pdf. http://www.nytimes.com/2014/07/27/bu...hird-less.html Mikek * net worth calculated as, the total value of all financial and real assets minus debts. |

It pretty much seems that way to anyone who isn't jealous of him. He usually forges ahead, but when he butts up against something unfamiliar, he asks. What's different about that from the way any competent tradesman works? "Just try anything and if it doesn't work we'll try something else" is a pretty expensive mantra (at the very least in man-hours, on a low-margin task), especially with all the varied experiences on tap on the web. Sometimes I hire 'experts' to solve materials handling issues (powders and dusts, not metal). Usually, it's worth the money. Pretending to be super intelligent, or super knowledgeable about anything, is not something that interests me personally. I have some things that I need done, like how to get copper out of a special transformer, and when I feel that I need to ask, I ask. Good move. If this makes me look bad in the eyes of "machining luminaries" like jon banquer and "precision machinist", so be it. bwa ha ha ha ha ha In their dreams. -- Aim for success, not perfection.

To feel good about oneself would involve running with some childish herd, and to keep coming out with sweet little lies.
Your best bet is to say what you actually know. You have to stop and explain everything to people in here like you are a kid, amdx. I bet you still haven't cracked an NEC manual yet either, have you. |
