Max’s Wheel Wrench: An extractor-based tuning wrench for removing pins from the pinblock. Features a SEIKO tuning wrench head (socket).

Overview:

Max’s Wheel Wrench is a specialized tool designed for efficient removal of tuning pins from piano pin blocks. It utilizes a large-diameter wheel to provide ample leverage, enabling the user to apply significant torque with minimal effort. The tool is designed for versatility and compatibility with various piano models, utilizing a modular design for easy adaptation.

The Max Wheel is a rotary lever mechanism that combines a first-class lever, a rotating element, and a wedge element. A distinctive feature of the Max Wheel is the location of the fulcrum (the wheel’s axis of rotation) above the point of force application (the hand), which creates a unique kinematic scheme. The applied force is converted into a rotational movement (torque) of the wheel, which is transmitted to the socket in a series of rapid, successive impulses, creating an effect similar to impact, but without the abrupt accumulation and release of energy as in impact tools. This design allows for increased force and efficiency in the rotation of the socket, ensuring more comfortable and precise operation.
