Cleaning The Tailstock; Aligning The Tailstock - Teknatool NOVA 3000 Instruction Manual

Cleaning the Tailstock

If the tailstock quill becomes hard to use or
the Handwheel is hard to turn, cleaning and
lubricating are required.
1. Remove the 6 mm set screw from the
tailstock. If necessary, turn the
Handwheel to expose the set screw.
2. Using a screwdriver, remove the
keeper plate from the tailstock body.
3. Remove the quill and Handwheel from
the tailstock body.
4. Wipe clean all parts including the
inside of the tailstock.
5. Lubricate the quill and tailstock slot
with a light-weight oil and apply a small
amount of grease to the quill threads.
6. Reassemble.

Aligning the Tailstock

1. Crank the Handwheel so the quill is
all the way in.
2. Place any #2 MT accessory you
have that has a sharp point like a spur
center, or live center in the tailstock
quill and another center in the
headstock spindle.
Note:Tailstock alignment can be
made easier by using the Teknatool
Acruline Accessory Center in place of
the centers.
3. Move the tailstock close to the
headstock so the two centers nearly
touch; check the alignment of the
center points. Move the tailstock away
from the headstock
and extend and lock the quill. The points of the centers should align when the quill is halfway extended,
fully extended, and fully retracted. If the centers are aligned at all three locations no adjustment is
necessary.
4. The tailstock does not meet the conditions in step 3, follow the steps below. This indicates that the
tailstock is not parallel to the lathe bed and you will need to realign the tailstock.
5. First make sure the tailstock alignment plate is not binding inside the bed. If the tailstock doesn't move
freely then remove the tailstock and look for burrs or high spots on the bed rails or the alignment plate.
Using a smooth file remove any burrs or high spots. When done replace the tailstock on the bed.
6. Slightly loosen the two tailstock capscrews with an Allen wrench. Tap the tailstock with a wooden
mallet in the appropriate direction to align the centers. Check and adjust the positioning of the tailstock.
The centers should align when the quill is halfway extended, fully extended, and fully retracted, as
previously described in step 3.
7. Lock the tailstock in place with the Tailstock Clamp Handle and fully tighten the two capscrews. The
capscrews must be fully tightened in order to avoid slippage during work.
