Why won't the script rotate the part?

I'm trying to make a gate where if you click the wheel, the part would spin in place while the gate opens. The script below is separate from the script that opens the gate.

--Prototype

w = script.Parent.Parent.Wheel_Part
debounce = true

function turn()
    if debounce == true then
        debounce = false
        for i=1,450 do
        w.CFrame = CFrame.fromEulerAnglesXYZ(0,0,-.8)
        wait()
    end
    wait(1)
    for i=1,450 do
        w.CFrame = CFrame.fromEulerAnglesXYZ(0,0,.8)
        wait()
    end
    debounce = true
end
end

script.Parent.ClickDetector.MouseClick:connect(turn)
