Turbo Wood Lathes Troubleshooting: Quill Movement Difficulty

Created by Gabriel Izzo, Modified on Fri, 12 Apr at 5:05 PM by Gabriel Izzo

When experiencing difficulty with the tailstock quill movement on your Harvey Turbo Wood Lathe, it's essential to assess whether the issue stems from misalignment, damage, or a need for lubrication. Below is a step-by-step guide to help you inspect and possibly resolve the issue:

Steps for Removing and Inspecting the Tailstock Quill and Lead Screw

1. Unlock the Tailstock:

  • Begin by loosening the lock handle (201) on the tailstock to free the quill.

2. Extend the Quill:

  • Rotate the handle until the quill, also referred to as "sleeve" (204), is fully extended outward. This action exposes the components for easier access.

3. Dismantle the Handle Assembly:

  • Remove the set screws (208) that anchor the handle to the end of the lead screw (205).
  • Carefully take off the handle (209), followed by removing the position ring (206) and washer (207).

4. Remove the Quill and Lead Screw:

  • With the handle components removed, proceed to extract the set screw (141) that holds the quill assembly in place.
  • Gently pull out the quill/sleeve (204) and the lead screw (205) through the tailstock, ensuring no undue force is applied that could cause bending or other damage.

Inspection and Maintenance

1. Examine for Damage:

  • After removal, separate the lead screw from the quill by unthreading them. Thoroughly inspect each part to identify any bends or noticeable distortions.
  • Check for wear, burrs, or foreign material that might obstruct smooth operation.

2. Cleaning and Lubrication:

  • Clean both the quill and lead screw along with the interior of the tailstock using a suitable cleaner such as WD-40. This helps remove old grease, dirt, and any corrosive build-up.
  • After cleaning, wipe down all parts to ensure they are dry and free of any cleaning residue.
  • Apply a high-quality, general-purpose grease to the threads of the lead screw and the exterior of the quill. This lubrication is crucial for smooth movement and to prevent future sticking or binding.

3. Reassemble and Test:

  • Reinstall the quill and lead screw by following the disassembly steps in reverse order.
  • Once reassembled, test the movement of the quill by extending and retracting it to ensure it moves smoothly without resistance.


If after these steps the tailstock quill still exhibits difficulty in movement, further investigation into the alignment of the tailstock or potential wear on the internal mechanisms might be required.
