I am sure this is not an original idea and that this has been covered amply over the years.
However I thought I would share it because it got me out of a bind while I was
soldering wire-wraps onto an LCD display.

I tried using the smallest sized alligator clips I had and even grinded some of then
down to narrow the "jaw" lines. As soon as solder touched it, it became soldered to
the pins as well. I could see myself ruining this repair.

Having no brass or aluminum alligator clips I started scrounging around and remembered
my wife's make-up desk. Sure 'nuff...she had some long aluminum clips that I could
grind down that would work nicely as a soldering heat sink.

One suggestion: If you use the "Goody" brand of hair clips you will have to modify it
a bit. First, they made them very cheaply and the tension spring isn't even secured inside the clip; it just sits in a little trough. I also drilled out the crimped pivot points and inserted a pop rivet wire through one jaw, into the center of the spring and then exiting out the other jaw's side. I could not rivet it; I just used a 1/8-inch pop rivet wire because it was the right size. A nail would work just as well. I terminated each side of the axle by using the pop rivet "head" on one side and, on the other, I placed it in a vice and use a chisel to flatten the axle as it came out of the jaw. When I smacked the chisel it not only flattened the side I wanted to hold it in place but, at the same time, it cut off the excess length of the pop rivet wire; so I got a "two-fer."

Now, where did I put my bobby pins? My hair's a mess.

Just the thing for" a bad hair day"... :wink:

Great tip, and I personally haven't seen this idea previously posted on the forum.

A very good idea!

I'm a regular at our local beauty supply place - it never ceases to amaze me how many things they sell that turn out to be useful in the hobby.

For future reference, brass solders quite readily. Steel is harder to solder. I've never heard of aluminum alligator clips, but I wouldn't be surprised if there were some Chinese ones.
