Default Crimping large cable lugs without a crimper

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.

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.

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.

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.

Yes I have seen them considering that I have a T&B crimper hanging
in the shop. 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.

I don't see any pictures of the bench toggle-action type on eBay--
just the hand-held type. Is that the kind you're talking about?

They're hand held like a bolt cutter though they do have a over
center toggle action. Here's a picture.

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.

I have the same crimpers. The stripe pattern on the
terminal barrel indicates how many crimps to make. I
suspect the dies that Spehro is describing make the
required number of crimps in one shot.

Yes, one shot.

BTW, here's an interesting product that might help-- I have not seen
these before- they look like a sort of collet terminal:

The hammer type crimper is on that page as well. I'm not fond of
them myself at least when used with a hammer. You never know when
you've got enough crimp or to much. I'm sure they'd work ok in a
press.

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.

Well, it IS a deprecatory term, not of the people at large, but of their
business culture and the quality of their metals.

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.

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.

There's a lot to this. 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.
