The fine feed knob on the mini mill makes it difficult to smoothly lower the head, which is important when performing operations like boring. Since I had a handle left over from installing the leadscrew handwheel on the lathe ( http://benchtopmachineshop.blogspot.com/2015/01/lathe-z-axis-fine-adjustment.html) I drilled and tapped a hole in the existing knob and installed the handle. Now it's much easier to consistently feed with the fine feed knob.
|Handle installed. Um...just ignore that other hole...|
