    1725/60=28.75 is the out from your reduction gear unit

    and you want 33 rpm

    28.75/33=0.87

    33T driver and 29T driven

    1725/60*33/29=32.75 rpm

    Suppose motor shaft has 10 teeth per turn, then output shaft needs 600 teeth to obtain 1:60 ratio.

    You need 2 sprockets 1 with 10 teeth and the other with 87 teeth.

    1725 RPM / 1:6 ratio = 287.5 RPM / 33 RPM = 8.7:1 ratio = 10 teeth / 87 teeth = 33 RPM.
