The Ultimate Primary Tap?

After melting several fuse clips and other quick and dirty taps on one
of my DRSSTCs I decide it was time to make something better. I didn't
want to spend much time or money on it so this limited me to parts one
hand. Here it is: http://www.hvguy.4hv.org/tap/

The construction is obvious from the pictures. First a small pair of
needle nose vice grips is used for the clamp and some 1" x .125" copper
bar for jaws. The copper was first precisely formed around a .625" steel
bar using a hammer on the floor. It was then cleaned and brazed onto the
jaws of the vice grips. Throw in a 1/0 screw lug and buff clean with a
wire brush and we're done.

This thing works great! It is fast, reliable, and will clamp onto copper
tubing from .375" to .75".

Of course I am using this with a vertical primary, it would have to be
changed for use with a flat primary, perhaps making a set of 90 degree
jaws and insulating the pliers but I though I'd throw the idea out
there.
