Is there any advice or tutorial on properly crimping a wire to the NAR stainless steel micro-clips?
Yes, get the proper crimp tool for those fasteners. Expect to pay $30 or so for it... you aren't going to get a good crimp with a pair of pliers.
I crimp and shrink wrap.
Are the clips not for soldering and the crimp part is just for securing the wire and is crimped on the isolation?
Soldering Stainless Steel is very problematic. You have to have the right solder, the right flux and the right heat and even then it isn't a very easy process.
Considering the most common failure mode I've seen is the wire breaking where it flexes at the solder/crimp point. The shrink wrap acting as a strain relief is probably the best thing you can do to extend the life of LPR clips whether they are crimped SST or soldered copper.
I simply use these Hirschmann AGS-30, there you can put a banana plug in the back
Where is good place to purchase clips?
amazon or mcmaster
www.mouser.com stocks both the BU-34X ($0.72) micro-clip and the larger BU-60X. ($1.03)
I watched a YouTube video on how to crimp alligator clips. The method the guy used worked great. Strip the end of the lead, fold the wire back over onto the insulation, insert into the back of the alligator clip (like the one Thomas shows in his post) until the wire is all inside and then crimp. I assume the crimped area will eventually come loose, but the alligator clip will almost certainly be destroyed by then. Just cut off the old clip and replace with a new clip.
