Inside the 2 folders youâ€™ll find all the necessary files to build your own fourth axis.
There’s an Imperial version that uses a Âľ” X 6″ bolt. In fact,itâ€™s the one Iâ€™ve made and it works.
I also modified the plans so you can use a 20mm X 160 bolt. But I didnâ€™t print this chuck, the gears or this case. I just asked someone to test if my new size bolt M20 is screwing and it was working. But I canâ€™t guaranty it myself.
If you manage to make this fourth axis, I would like to see pictures of it and also know if my metric design works as good as I thought.
The Imperial case requires 2 bearings with an interior of Âľ” and an exterior of 1Âľ”.
The metric case requires 2 bearings with an interior of 20mm and an exterior of 42mm.
Along with the files, there’s the GCODE files that I used to cut the case. But to manage to have the right size for the bearing’s holes, I was forced to tell the program I used( Vectric Aspire) that my router bit was 0.085″ instead of the 0.125″ that I actually used to cut it. This had the effect of cutting the holes at the right size. I canâ€™t predict if your CNC will cut like mine; youâ€™ll have to try it and if it doesnâ€™t, youâ€™ll have to change your settings accordingly.
A good chunk of the chuck comes from this design on thingiverse https://www.thingiverse.com/thing:2796900
I did work hundreds of hours to make all those free files.

Good luck and have fun with your fourth axis,
