Ayuy...that should work well too..particularly if the copper is held
solidly by the varnish.

Id sharpen the chisel a bunch though..most tend to be quite blunt

Ummm.... this ain't 'magnet wire', guys. The connector tabs are 2" wide
by about 1/2" thick solid copper. In the water cooled units, some of the
secondary 'wire' is thickwalled copper tubing as much as 1" diameter for
the water cooling, and any that's not is probably square-section 'wire'
at least 5/8" on a side.

I'm guessing it would take a real man of an air chisel to work through
some of that stuff. Having done it before, that's why I suggested a saw.
