OPTIONAL
PARTIAL DISASSEMBLY OF THE MILL
If a hoist is not available, and the mill has to be moved by man-
power, this is more manageable if the headstock and table are
temporarily removed.
Not a one-person procedure
.
Table removal
1. Remove handwheels, support brackets and other compo-
nents from both ends of the leadscrew. Set the parts aside
in separate left-hand/right-hand containers.
2. Remove the gib from the front dovetail.
3. Slide table to one side then lift it clear, taking care not to
damage the dovetails.

Inset: Use a telescoping magnetic pickup
tool to retrieve/reposition T-bolts
Headstock removal
1. Assemble a stack of 2 x 4s as Figure 1-4. Lower and lock
the quill so that the spindle nose rests on the front 2 x 4
(this is for balance, not for load bearing).
2. Crank the headstock down to the point where the head-
stock is felt to be pressing firmly on the back 2 x 4s —
firmly
,
meaning the headstock will not suddenly shift
when its two attachment nuts are loosened.
3. With another person on hand to stabilize the headstock,
remove the two attachment nuts, then move the table for-
ward clear of the T-bolts.

11. Roll the mill into position over the chip tray, then lower it
into place, Figure 1-3.
12. Secure the mill to the bench or stand. If this is a stand in-
stallation, use the four bolts M8 x 100 mm bolts supplied.
Use plain and lock washers in all locations.
