You know, that would have been my first try, but the screws are
indented (*******s! g).

I have a Dremel tool, but now I'm wishing I had bought the vari-speed.
The full-speed one is great for cutting circuit boards, etc. but a bit
scarey in this application. I also don't like the thought of a blade
flying apart at such a rotational speed. I saw that with a sanding
disk once...Impressive enough.

Is there a light-weight, low-powered tool that does this kind of thing
well? Probably a small, versatile battery-powered drill of some kind.
Between a battery-powered screwdriver and a plugin Dremel.


You might try a "worn down" cutoff
wheel. When worn, the diameter can
be as small as 3/8". Not knowing the
exact geometry of the drive, it's hard
to know if this would work. You still
have to physically get the tool in the
area. BTW, use safety glasses ... these
wheels can fly when they break up
and they WILL break.
