Assembly

Assembly of the small components of the mill consists of attaching the ball handles, knee crank, and the way covers.

To assemble the mill:

1.remove the hex nuts from the X- and Y-axis leadscrews, then slide the ball handles (Figure 10) onto the leadscrews and secure them with the hex nuts.

Note: Tighten the hex nuts just until they are snug. Overtightening could increase the wear of the moving parts.
