Logan Lathe CNC Conversion

The next step is to attach the Z-axis ballscrew nut to the saddle. I'm going to get a bit
convoluted on this one, but the reasons for it will be clear in a few pages.

My first idea was to go with heavy angle- I didn't have any the right size, but this
hunk of aluminum channel from my bins gives the idea of what I was shooting for.

A brief sojurn to the local metal supplier provided me with an 11" long chunk
of 4" heavy aluminum angle, and a 3" long chunk of 4" diameter round.

One leg of the angle needed a significant trim, which the DoAll bandsaw handled easily.

The trimmed angle will fit more or less like so, and become the new "apron".

However, the Logan saddle has this adjustable gib bar underneath, so the 'apron' will need to be machined to clear it.

And it's just that easy. A few quick measurements, a few minutes in the mill....

And it fits like a glove.

Finally, the two mounting bolts holes are drilled and tapped on the short leg,
and the ends are trimmed to match the saddle. Next, the ballnut mount itself.
