pre-assembled, or would I have to make one myself? Thanks.

Find an amusement machine vendor in your area who still does pinball
machines, and get some drop target reset solenoids. I used to work
repairing pinball machines (and juke boxes, Pac-Man, and so on - kewl
job!), and was tempted to use them in a piano project of my own, which
never materialized. (sigh)

If you've ever played pinball, you've seen drop targets reset - the
stroke is maybe 1-1/2", and they don't have a lot of force (they raise
those little plastic targets, which latch in place), but by eyeball
and gut feeling, they looked like they'd be ideal. You'd have to
carefully control the current, to give the attack and sustain that
you want, of course.

Good Luck!
