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 ??

Know anybody with a bandsaw?

I think the school has one, but would still be concerned about fingers.

Probably the safest way if done right. You use a push stick behind
it. Safer that a hand held knife.

Guide and push stick, safe and fast.

Not sure how well a push stick would control a round ball. Maybe if I
created a custom shaped stick ??

I'm thinking something like a 2x4 with a tennis ball sized hole drilled
into it and a channel for the bandsaw blade. It may require a little
refinement so the captive ball doesn't rotate when it comes into contact
with the ball. You could even clamp a stop to the table to get an
uniform depth of cut.

People see making a jig first as a waste of effort, but the time would
be repaid by about your 95th ball.
