Fixing your cable problems forever.

Rats. There was some good info on that thread. 

Let me ask a couple of questions about cable making:

Do you start with raw, exposed copper or is there always some insulation on it to begin with?

I've soldered connectors for a different type of cable so I've got experience there.

So if it is a matter of adding connectors, additional insulation, shrink wrap, etc I could do that.

Again the question of cost. Is it possible to do it for less than what you'd otherwise pay for?

Here's an example of what I'm talking about:

BUT!

Some people like to make their IC's nearly naked. They use solid bare copper and wrap it in cotton sleeves. So long as your voltages are low, this is fine, but you won't get the same noise rejection.

It's quite a trend.
