Phase Six: Z-Axis

HOME

A shot of the thrust bearing setup made from a rollerblade bearing that is held captive by a small plate. This allows for some adjustment before the screws are tightened. Thanks for the idea John Kleinbauer!

 

Another shot of the thrust bearing.

 

I still need to machine the hand wheels that will mount on the end of the lead screws.

 

The z-axis is going to use 1/2" CRS for ways and bronze bushings to hold the carriage assembly.

 

Z-axis nearing completion.

 

Z-axis test fit to the TK-421.
