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.

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.

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.

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.

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.

LLoyd
