Descriptions

Quern
A manual grinding tool with two stones; the top stone rotates over the bottom to crush grain into flour. Used historically and by small-scale bakers and enthusiasts.
Quoin
A metal or wooden wedge used to lock and secure type in a press chase. Tightened with a wrench or key to hold a layout firmly during printing.
Quadrant
An older angle-measuring instrument used in navigation and surveying. Functions like a large protractor to determine altitude or angular position.
Q-meter
An electronic meter that measures the quality factor (Q) of coils and resonant circuits, useful for tuning, antenna work and RF testing.
Quilting frame
A frame or stand that keeps quilt layers stretched and aligned for hand quilting or longarm stitching, improving stitch accuracy and speed.
Quilting hoop
Two concentric rings that clamp fabric taut for quilting or embroidery. Lightweight and portable for hand-stitching small areas.
Quick clamp
A one-handed bar clamp with a trigger for fast clamping and release. Great for gluing, assembly and temporary holds.
Quick-change toolpost
A lathe accessory that holds multiple tool holders, allowing fast, repeatable tool changes to speed turning operations.
Quick coupler
A fast-acting fitting used on air hoses, hydraulics and fluid lines, enabling tool-free connections in workshops and equipment.
Quenching tongs
Long-handled tongs designed to grip heated parts securely while quenching in water or oil, protecting hands and improving control.
Quench tank
A tank filled with oil, water or polymers used to rapidly cool heated metal during heat treatment to change hardness and mechanical properties.
