I've got access to a crimper(looks like a big bolt cutter) at work but I can't borrow it. i need something I can take with me so I can make cables up at the farm, or at home, depending on where the tractor is.
Ive got a set, sold by AMP, runs from 8 gauge to 4/0, probably 20 years old, its yellow in color, the heads of the crimper have rotating dies. I think I dropped north of $400 for them in the late 80s. still using them. I like making my own cables. I just googled mine, it now sells for $1059.00

, better keep an eye on those..
Any of you guys use solder, or compression fittings on battery cables ? I do all three (crimping being the third). Cant remember the brand, but for car work, I like the compression ones, they are cast copper, coated in tin. I always shrink wrap the ends when I'm done. They are fast, work great, last, and look good. When I'm worried about high amp draw, and durability is not an issue, I do the solder style.
