This is probably obvious, but I just wanted to make clear to the OP - increasing the winch drum diameter will increase your speed at the expense of torque. Think of it like the opposite of a gear reduction. That said, the greater diameter the winch drum is, the greater torque your spring force will put on the output shaft upon release.

A quick and dirty way to make a bigger winch is to throw some hex hubs on the shaft, the kind normally used for sprockets and wheels.
