Aligning the Tailstock

1. Crank the Hand wheel back so the quill is all the way in.

2. Place any #2 MT accessories you have that have 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 double ended NOVA Acurline Accessory

Center (SKU: 2MTNA) 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. If 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 (A) 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 (A). Using a smooth file remove any burrs or high spots. When done replace the

tailstock on the bed.

6. Slightly loosen the four cap screws (B) securing the tailstock ailment plates (A) with a 5mm 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 four cap screws (B).

The cap screws (B) must be fully tightened in order to avoid slippage during work.

8. Check the alignment of the Tailstock by bringing it together with the Headstock, with the Live center

and Spur center in each spindle. The Points on the centers should be within 0.50mm (0.020") height and

width of each other
