My wheel is a 15" Grant GT. I have a 4" pulley connected to the wheel
axle with a length of curtain cord strung through the pully parallell to
the floor at the center of the pulley. Turning the wheel winds up the
cord and pulls two springs, one at each end of the cord. It also starts
to lift two 10 pound window weights, so the more you try to turn the
wheel, the more resistance you get, and when you let go, it self centers
like crazy with no *** back and forth from center....
