Need to cut an 1.5" X into 96 tennis balls. (To attach to classroom
chair legs, if you must know ;-)

So far, a box cutter is not getting it done, neither a small "cutting"
wheel from a dremel kit

Best so far is with ball held in a vise, and using a miter box saw to
cut 2 1.5" slits in ball to form X. But this is a bit tedious for 96 x 2
cuts.

Thought of a table saw, but fingers would be too close to blade for my
comfort

Tried looking for a dremel type cutter that would go in a drill motor,
but haven't seen anything I want to pay for if it does not work any
better than miter saw.

Any suggestions ??

I would try a powered reciprocating saw.

Hhmm....... I could try mounting my jigsaw in the vise, if i can
"cushion" it to stay in place.

I think all these power tool ideas are bad ideas. Dangerous. It's not
wood, You can make a jig to hold the tennis ball, just 4 two-inch
books would probalby be enough, or you can nail some 2x4's together and
then use a sharp knife witha sharp point. Non-folding or with a latch
that keeps the knife fromfolding.

The drill press and Forstner bit appears to me to be quite safe.
