RE: Safety gap electrodes



Hi all,

 Hit up a few "mom&pop" computer stores, see if you can get a few dead
computer mice.  The mouseball is usually a rubber-coated steel ball.  Peel
awat the rubber ceating, drill & tap, and you've got a perfect electrode.
I'm a MIS, so I just "collect" all the dead mice from work and get my saftey
electrodes that way.  They are steel, which is a drawback, but they're
almost perfectly round (a few small flat spots usually), and relatively easy
to drill and tap.  A good vise and a sharp bit go a long way in making it
easier.  I drill and tap mine for 10x32 brass rod, so I can set the gap
easier.  The mouse balls that have a steel core are easy to tell, they weigh
a lot, and they don't bounce worth crap. (amazingly little rebound on 'em)
Works for me!

Hi
     Use "Chinese Finger Balls"- they are perfect for the job, but they are
chromium-plated. They can be welded to studding for fixing.
You can purchase them from many shops that specialise in knick-knacks and
tasteless trash..... there's one in every town.
