Why wind by hand like a schmuck?

From Dunlop: The Universal Speedwinder makes for fast string changes that are easy on your hand and wrist, featuring a lightweight design with low-friction rotation and a comfortable, ergonomic handle. The universal head fits most guitar and bass tuning machines, and the handle includes a handy bridge-pin puller that stays tucked away when you don’t need it.
