Crimping large cable lugs without a crimper
"Ignoramus25589" wrote in message ... I will soon need to crimp many terminals on many short, but thick, 1 gauge or 0 gauge cables. Crimpers are just too expensive. Is there some way to get acceptable crimps without a crimper. I guess, also, that I could buy one on ebay and later sell it, but I would prefer to avoid that. Sure there is. Buy an inexpensive pair of Chinkalloy bolt cutters, and grind the profile you need into the blades. You can probably have the tool for $12.00 and a half-hour's work. LLoyd |

LLoyd Have you seen what the proper T&B dies for this sort of application look like? They are *not* just your cheap crimper scaled up-- the barrel of the lug is *swaged* down on the leadwire with interleaved fingers on the die set, not just collapsed inward in a small section. That's why they don't come loose. Best regards, Spehro Pefhany -- "it's the network..."

Yes, I've seen them, and I've done a lot of it for electrical and weight-bearing equipment -- both with the right Thomas & Betts and AMP crimpers and with makeshift tools. You can make up in technique a lot of what the right tool would do automatically. Crimps aren't magic. Put the right profile in the jaws, and you can "step" the crimp down the barrel as required. When anyone tells me I can't do a workman-like job with tools I've done it with, it kinda leave me thinking they don't have much imagination. Stretch your mind a bit. LLoyd |

LLoyd Greetings Lloyd, Not to be too "politically correct" but I find "Chinkalloy" offensive. Not because lots of stuff made in china is ****ty, but because the word "Chink" is used to insult someone who is or is percieved to be Chinese. It is not used as a descriptive term except in a way that is designed to denigrate someone. And there is no doubt that the reason so much stuff from China is of low quality is because the people making it are told to do it that way. Used to be that "made in Japan" or "made In Korea" was a pretty good indicator of quality. But now Korea and Japan turn out excellent work. Anyway, I'm just a reformed bigot who is trying not to be one and pointing stuff out like the above helps a little. I'm sure you were not trying to be a bigot and saying "Chinaalloy" really doesn't flow off the tongue so well but there it is. Cheers, Eric R Snow, Not trying to be the thought police, just excersing my freedom of speech too. |

I don't see anything to them that couldn't be duplicated in a pair of cheap bolt cutters of the right size. I would want to know the size of the opening (easily done since they're hanging right there for me to measure) but other than that definitely doable for one or two sizes of wire.

They're hand held like a bolt cutter though they do have a over center toggle action. Here's a picture. http://www.tecratools.com/pages/tele...ics/39204l.gif http://www.tecratools.com/pages/tele...bcrimpers.html Scroll down to the TBM5S. Mines not the S model with the sure stake mechanism. But that's not a problem for me since I'm always going to go the full stroke (unless something goes wrong). Good for 8ga to 250MCM so they're more than ample for the 2/0, on down that I use them on. Wayne Cook Shamrock, TX http://members.dslextreme.com/users/waynecook/index.htm |

Crimping large cable lugs without a crimper
When working for Schlumberger, we had a tool chest tower of drawers -
full of handles of all sizes and the rest were dies for specific wire... When dealing in high rel and very high current lugs items like this are required. Lower level of requirements lend lesser quality of crimps.

I deal directly a LOT with nationalist Chinese in my business. (fireworks) I don't think of myself as much of a bigot (we all have some tendency to be socio-centric), but find a lot of cultural and 'moral' aspects of their business-doings repugnant. They are - by practice and approval of their culture - cheap, deliberately averse to quality, and dishonest. It shows in everything they make, and every relationship they establish with us here. So, yeah.... I guess what I'm saying is my opinion boils over into my description of the metal. Ok... I'll try to force my muscle-memory into typing Chinalloy instead. LLoyd |

wrote: Let's be mindful of one thing. There is a concept called "fundamental attribution error". It is a mistake of attributing observed behavior to some inner qualities of an individual, rather than mere circumstances. These Chinese people may be acting the way they act, because of simple economic incentives around them. There is probably something cultural there, because it works in both China and Taiwan. Quality is more a fixed attribute in the US, Japan, Canada, Germany etc. In China or Taiwan, if you negotiate the price of a widget down from $50 to $40, they'll tend to find a way to build you a crummy $40 widget, not sell you their $50 widget for $40. Also, they are used to living with defects in their everyday life- in clothing, appliances and that sort of thing. A button that needs to be resewn, a slight color mis-match, a thread out of place, a paint blemish are not big deals. They have to be taught that it *is* a big deal to us. A guy making a salary of $150 per *month* thinks he's a hero if he saves a couple of dollars on a reel of 10,000 components, for example. He doesn't necessarily realize that a few more failures at our end at $20-$100 per hour will blow away any savings many times over. They also deal with customers in places like India, where they can accept 15% or 20% DOA product (really) at a sufficiently low price, because it's so cheap to have someone go through it all. For them, it's sort of like us dealing with a really fussy Swiss (say) customer who's always complaining about paint finish and other irrelevant (you might think) details on the stuff you manufacture, and threatening to send the whole shipment back because of few smudges or whatever. But he pays well, so you put up with it and try to give him what he demands. Sort of like car mechanics. An honest car mechanic would probably not stay in business very long. So, they act like scum, and yet if they go into another line of business, they might suddenly change into honest, upstanding businessmen. It's been said that 20% of people are inherently dishonest, 20% are intrinsically honest, and the rest go either way depending on circumstance. snip Best regards, Spehro Pefhany -- "it's the network..."

I believe that until recently the Chinese government encouraged companies to make pirate copies of books, videos DVDs etc. Actually they might still, but I'd heard it was changing. Chris |
