The first video covers the plan for the placement of the Z axis ball screw inside the column.
Next video shows making the arm to connect the milling head to the z axis ball nut
Here is the milling of the slot into the column
More work on finishing the clearancing in the column for the Z axis ball nut and screw
Final part 3 video on the clearancing inside the column
Here's my first attempt to straighten the base. This shows some of the challenges of the weak casting on this machine.
Here I am getting into what is being done to stiffen the column
Here is the second part explaining the stiffening of the column
Here I am cutting the gussets
Here is with the gussets mounted explaining how they will work
This is a fun video where I actually measure how square the column is before I correct it. I also apply a force on it and measure deflection to show rigidity
Here’s the fine adjustment I’m going to use for the column
Here a test piece I made for the cam
In this video I show how I square up the casting bracket for the column
This video shows the completion of building the gussets, mounting them, indicating the column in straight and a final test of the more rigid state of the column after the improvements.
