Ok, a little different approach, since you're making 50 of them.
Route the shape in a long piece, or if you need a different grain orientation, cut the same profile in several short pieces. You'll wind up with what looks like a piece of molding. Then cut off pieces with a narrow kerf blade for your final result. Make the length at least twice what you think you'll need so you have some backup. Support the back of the piece with a sacrificial fence so that the cutoff piece is supported as the saw goes through. Still, I'd expect a number of pieces just won't make it--it's wood! Making these one off is not practical.
The more I do, the less I accomplish.
