Of course, one major difference between a boat and a well is the boat is going places, and the well isn't moving. Sway's really good at comparing apples to oranges.

Since the original post is over a year old, Maine Sail has had time to chill out on the crimper thing. Yeah, he cares about this stuff. Glad somebody does! His product comparisons and repair tutorials are brilliant & invaluable assets to this forum.OK, we mostly agree that HFT makes caveat-emptor crap. Ancor makes good stuff, but some of us find it expensive. Can you all stop the testosterone-charged ranting and raving now?
Wow never thought I'd see this thread again..OK, we mostly agree that HFT makes caveat-emptor crap. Ancor makes good stuff, but some of us find it expensive. Can you all stop the testosterone-charged ranting and raving now?
I am going to order a Molex 64016-0037 from Digikey. Molex makes good quality terminations and tools, and I don't have to pay a yachtie premium for them.
See for yourself: Digi-Key - WM9986-ND (Molex Connector Corporation - 64016-0037)
I have 3 indian virgins crimp all of my connections.
one holds the wire and connection in her teeth,
the second one whacks her on the head with a rubber mallet.
the third one screams.
I'm not sure if it meets any standards but mine.
If you look a the leverage ratio on the "red" crimpers (36:1), the force (40#), and the area (about 0.03sq " on 12ga) the local force is ~ 48,000 psi. Since the yield strength of copper is ~ 33,000 psi, it is going to flow. Less than the figure you quoted, but in the ballpark. The plastic is going to be a mess too, no question. I think that is obvious, since the compressive strength of HDPE is ~ 10x less.The idea that a connector is 'swaged' through the plastic insulator is just ludicrous. That it makes an airtight connection is also ridiculous. I've done lots of wire crimping, all the way up to 500MCM cables, using our T&B 15 ton hydraulic crimping tool. Yes it DOES squeeze the spaces and air out from between the strands! 30,000 lbs of force against an surface area of about 1/2 square inch on copper or aluminum will do that. No hand powered crimper, even those big red handled ones can do that. I've cut the crimps apart myself to satisfy my curiosity. None the less, properly made crimps do work well.
I hate junk tools. My expensive Milwaukee pistol drill that is now 35 years old and has been used extensively for tapping still makes me smile when I use it.
