    I wrote a little gear ratio calculator that some might find handy. The program can be downloaded from http://jimsitton.net/ratiocalc/ Just right click on the file gearratio.exe and select "save link as" and put it somewhere you can find it again. Once it's saved, double click on the gearratio.exe file and it will run.

    The program allows for up to three ratios in series. If you have fewer just leave the unused ratios set to 1:1.

    The program will also calculate speed based on engine RPM, drive ratio,and wheel diameter. Be sure to measure the outside diameter of your wheel for accurate results.

    If you have any questions post them in this thread.

    Have fun!

    For friction drives:

    Leave all ratios set at 1:1

    use the diameter of the friction drive roller, not
    the size of the driven wheel, as input to the wheel diameter field.
