Saddle Nut with Oiler

Any older Sherline mill can be upgraded to add the new Z-axis saddle nut with oiler. Simply purchase the upgrade kit P/N 4017OL (41177OL metric), which includes the oiler and a new saddle nut. This is in keeping with our goal to make all accessories and improvements compatible with existing machines,

All Sherline mills now include oil reservoirs on the X/Y axes and the Z-axis. It helps to keep critical parts lubricated. These were initially developed for CNC machines that run constantly for hours on end. They can benefit manual machines as well.

For mill Z axis only.

Column Saddle Upgrade

Also available but sold separately is the Column Saddle Lock Upgrade w/ Oiler. Sherline mills produced before 1999 used a nylon friction lock that is made tight using a socket head screw. It squeezes against the back side of the mill column gib and dovetail. With the introduction of the Model 2000 mill in late 1998, we changed the way the mill saddle was locked.

The new system utilizes a brass lever on the leadscrew that locks against the top of the saddle nut. This provides a more secure lock that requires no tool to tighten. Older machines can be upgraded to the new system with the addition of this new locking lever and a new saddle nut that has a spring-loaded ball to keep the lever from self-locking when the leadscrew is turned.

If you are replacing a worn out saddle nut on an older mill, this new system will upgrade the function of your machine at the same time. Even if your saddle nut is not worn out, you might want to consider adding this feature to make locking the saddle easier and more positive.
