How do you guys tie together the strands at the ends of your heavy-wires to ensure a good connection to screw-terminals? Solder?

It's best not to solder as the solder creeps and eventually gives a bad connection. Just use pliers to make the strands lie neatly together and do up the screws tight.

what are you connecting them too with screw terminals? i always use crimped conections on the larger wires. but thats just me.

I like to tin the ends with solder to stop any stray strands causing problems - not enough to prevent the screw terminals from grabbing hold though.

with those connectors, strip off the insualtion, screw down tight, job done.

I've used those type. I messed up the first attempts, but soon found that if you strip them carefully without twisting them they went in a treat. I also made sure there was a couple of mm showing through at the tail end too

split a length of copper brake pipe about 25mm length wise open it up and put on top of the wire that way the screws have something to press down on.

Cheers Tony. That's a good suggestion!

How can solder cause a bad connection?
The solder fuses to the copper strands sealing the end of the exposed cable so preventing oxidisation of the strands and so keeping the resistance of the condutor as low as possible. Also the solder mechanically strengthens the cable when the screws are nipped down so preventing the strands being sheared by the end of the screw.

In my experiance crimp only connections always fail before solder ones do.
