Default Anyone have a bench crimper?

I've assembled most of the components, and I'm soon going to be doing a bunch of heavy-gauge wiring on my LX.

Does anyone have (or know where I could "use") a bench crimper for #4 and 1/0 gauge wire?

I've heard that West Marine has them for use (if you buy "stuff" from them), but I'm not sure if the one off the 470 does?

TIA!

I drive by everyday, I can stop and ask if you want.

Why not solder?
I have have always been told it is the preferred method. I did it on all my heavy duty wiring (dual batts, rear power, etc) and I have had zero issue.

Thanks, Mike. Yes, please.

All of my research led me to conclude that high-quality crimps (all the way around with high pressure) are the way I want to go.

I've got the cable & all of the accessories, except for the lugs.

My options in preferential order:

1. "Borrow" a bench crimper from a club member (with all of the 80's & 100's in the club, I figure its likely SOMEONE already has one).

2. Buy my lugs from West Marine and spend a day up there doing the final install.

3. Pony up for one (not attractive, as it is for basically one-time use).

Hants....

Remember this thread? --> 2 ga Cable/Wire Crimping


West Marine does in fact have the bench and tools needed to do the job and I believe Matt put the stuff to use when he did his winch install recently.

For me, I went ahead and bought a "swager" that seemed to have done the trick for me and my issue I had (see the above thread). Not sure it will do 1/0 cable but it handled the 2 ga no problem. You're welcome to borrow it but its likely to cost more in gas than just picking one up. IIRC it was ~$35 and the only negative really was that it takes awhile to get it all lined up and tighten down the bolts. At the time I did the repair I considered it a temporary fix but it has been like this since last year. There is little to no stress on the connection and the liquid black tape stuff works perfectly to seal out moisture etc.

West Marine has a crimper that I have used on several occasions.

So I'm not much of an electrical person so please correct me if I am wrong.

What I have done in the past has been to crimp on the part and then solder it afterwards. Then either shrink or the liquid goo. Is this overkill or ????

I am going to be adding a second battery soon and will need to do the same.

I feel you really need to crimp and solder the connection. I use the dull center punch and hammer method for crimping (that's exactly what an hammer indentor tool is doing) and solder for the corrosion protection. But it's important to crimp for the mechanical connection and the soldering is secondary and wrapping the crimp with Coax Seal or using shrink wrap is an alternative. If you solder, using shrink is redundant, but does look nicer.

BTW, you can make your own die-style swaging crimper using a set of bolt cutters and an old 6 point socket. Cut the socket in half long-wise and weld it to the jaws of the bolt cutters. This is how we made our crimpers at a panel shop that I used to work, we had a set of swaging crimpers that cost us $150 for all 4 (6mm, 8mm, 10mm, 12mm). IIRC, for 4AWG lugs you would use a 6mm or 8mm socket for 1/0 lugs, a 10mm socket.

All smaller gauge wiring I do is soldered and heat shrank. High amp load wiring should be swagged. This is an old argument.....Google is your friend!
