Thanks this was what we were going to do in addition to the key and setscrews. We wanted to know if the setscrew was possible. We figured that it was needed to prevent the key from smashing around in the keyway and widening it.

Setscrews on keys are strictly to keep the key in place so it doesn't slide side to side axially. If it's "banging around" in the direction you're turning the gear, then the key is too small. Ideally, you get a slightly oversized key and file it down until it perfectly fits
