New (new) Z axis begun

January 31, 2011

So, after I struggled with the flexibility of MDF for a while (the V-Groove bearings were working themselves loose) I decided to bite the bullet and begin the all-alum buildup. As a test, I decided to do the simplest part. The Z axis.

So, I got a 16mm sheet of 5083 Alum custom cut from Action Aluminum. It is 190mm x 300mm x 16mm.

I promptly drilled the holes,

Tapped the thread to accept 1/4 inch (V-groove bearings were bought in the US.)

And mounted it to the machine. I must say the rigidity has increased tenfold. Amazing.
