Component Details:
- Design & Function: This dual-purpose instrument features a classic split-jaw miniature pin chuck operated by a knurled compression nut. It currently holds a highly precise, long tapered steel centering needle.
- Lathe Integration: The straight, uniform rear handle shaft is designed to be clamped into standard 6mm lathe collets, tailstock chucks, or universal runners. It allows the machinist to use the ultra-fine needle tip to check and eliminate runout when center-truing small gear blanks or watch wheels.
- Versatility: The chuck can be completely loosened to swap the needle out for micro drill bits, pivot broaches, winding stems, or fine wire stock.
Measurements & Scale:
- Scale: Standard US Quarter coin shown in photographs for exact visual scale reference.
Condition:
Excellent vintage workshop condition. The knurled chuck nut features crisp texturing and threads down smoothly to lock workpieces tightly. The internal clamping jaws are clean and square. The long centering needle is remarkably straight, true, and comes to a very fine point without any bending or blunting.
A classic, highly essential tool for any manual machinist, clock restorer, or watchmaking specialist using vintage precision machinery.
