Hi Henry.  For people like me who have an allergic reaction to anything
requiring manual manipulation, a diamond cutoff wheel in the dremel
or die grinder is a cheap alternative.

A diamond abrasive is something you just have to use to believe.  It cuts
brass, steel, tempered steel, ceramic and glass with equal ease.  "Ease"
being defined as cutting several inches per minute through, say, 1/4"
glass.  The key to making diamond work well is to keep it wet.  I
use either running water in the sink or a machine tool-type water mister.

My wife has a stained glass studio which is where I discovered diamond.
I had traditionally used tungsten carbide tools.  Diamond, as it
turns out, is less expensive than carbide.  My favorite cutoff tool, a
diamond wheel about 1" in diameter mounted on a 1/8" spindle, costs
about $12.  "Diamond drills", straight shanked burrs to us machinists,
are available in a wide variety of sizes, generally under $15.

My favorite source for these is an outfit called "Truebite Inc."
