    4th Axis, need ideas

    I found this picture online:



    And I would like to know what else is needed besides the chuck (already have one) to build a small 4th axis for my router table

    It seems there is no planetary or harmonic drive there. Im open to ideas too.

    Thanks

    Here is a nice harmonic drive, perfect fit for your chuck, about 2.65" dia. Small with zero backlash ----> http://cgi.ebay.com/Harmonic-Drive-H...QQcmdZViewItem

    Ratio seems to be 1:60; current bid $61.00 - as cheap as it gets....

    It's not what you take away, it's what you are left with that counts!

    What a beautifull work you did there Eric, but I dont have the machinery needed to do it, I wonder how much you would charge for the parts? I mean the disc and the harmonic drive support.
