I feel this little tutorial including the photos may be of interest to some people. I’ve not studied it in detail, and am no expert on these matters, but would be interested in what other think. Here is the link:

Should be a good upgrade to a buzz-box.

I`ve just noticed the photo whereby short pieces of 1/2" copper pipe are used to crimp the cables. I like the creativity element of that, but would it be possible to get a good tight crimp? How would this be achieved (assuming pliers would not provide a tight enough crimp)?
