Tailstock Movement; Alignment Between Centers; Headstock, Tool Rest Carriage And Tailstock Locking Lever Adjustment - General International 25-650ABC M1 Setup & Operation Manual

TAILSTOCK MOVEMENT

The tailstock is used to support the other end of the work-
piece to be turned and can be moved along the bed
sideways to suit the length of the workpiece H.
To move the tailstock on the bed:
1. Loosen the tailstock locking lever I.
2. Move the tailstock by hand to the desired location
on the bed J.
3. Retighten the tailstock locking lever to secure the
tailstock in position.

ALIGNMENT BETWEEN CENTERS

There is a small amount of play built into the headstock
on the bed to allow the headstock to pivot freely.
Whenever the headstock is pivoted back from the out-
board position, the alignment between the headstock
and tailstock centers should be double checked and
adjusted as needed.
1. Pivot the headstock to its normal spindle turning
position (0º) and lock it in place.
2. Install a spur center in the headstock and a live cen-
ter in the tailstock.
3.
Release the tailstock locking lever and advance
the tailstock on the bed A until the points of the 2
centers just barely touch each other.
4. Using the tailstock locking lever, secure the tail
stock on the bed with the points still touching.
5. Look down at the two centers from above B to ve-
rify that the points are in alignment. If the points line
up, proceed with normal turning operations.
6. If the points are not lined up release the headstock locking lever and manually adjust the headstock position
using the play in the head- stock to line up the center points.
7. With the points lined up, hold the headstock in place and tighten the headstock locking lever.
8. With the points lined up, proceed with normal turning operations.
HEADSTOCK, TOOL REST CARRIAGE AND TAILSTOCK LOCKING LEVER
ADJUSTMENT
The headstock, tool rest carriage and tailstock assemblies
use a cam action clamp to lock them in place along the
bed ways. You may need to adjust the cam action to
increase or decrease the clamping pressure. To adjust:
1. Loosen handle A, B and C until the component slides
freely on the ways. Remove travel limiters D on the
bed and slide the component off of the bed.
2. Using a 1- 1/16 th inch wrench or socket, tighten or loo-
sen the nut that is located under the donut shaped
wedge, E.
Turning the nut clockwise increases the clamping force
and counterclockwise decreases the force.
The (4) black locking levers that lock the quill, tool rests,
and the motor tension feature ratchet style handles for
easy positioning. Simply pull out on the spring loaded lever
and move it to a different position, then release it and it will
snap back onto the positive drive teeth.

can be adjusted without removing it from under the lathe
