How do I use a wiggler?
Use a wooden pencil or other object to press on the side of the probe near the point until it turns true, with no wobble. When you press too hard you will find out why this device is called a wiggler! Once you have the probe centered, turn off the power and center the mark on the work piece under the point of the probe.
What is a wiggler on a mill?
A wiggler, also known as a wobbler, edge-finder, center-finder or laser-centering-device, is a tool used with a machine like a mill, to accurately align the machine head with the work prior to machining. An edge finder is a rotating tool, meaning the machine spindle must be turning for the tool to work.
How do you use a wiggler probe?
Each probe has a large ball on one end that snaps into the body. The wiggler body holds the selected probe. Loosen the knurled nut and snap the ball on the end of the probe into the body. Tighten the knurled nut so the probe is not loose, but can still move.
What is a wiggler used for in dentistry?
A wiggler is used for aligning center-punched hole locations; it's basically a sharp pointed needle on one end with a spherical radius on the other. The radius is held in the body of the wiggler, which has a corresponding radius machined into the shank and nut which holds the point.

How does a spindle work?
This is a rotating tool, meaning the machine spindle must be turning for the tool to work. On one end a cylindrical shank, a second cylinder is attached by a spring running through the center of both cylinders. The second cylinder rotates with the first. They two are always co-axial, but the mating faces are able to slide against each other. Thus the second cylinder can rotate about a different, but always parallel axis to the first. As the second cylinder approaches the edge to be located, it is pushed into alignment with the first. When the horizontal distance from the workpiece to the shank is exactly equal to the radius of the second cylinder, the second cylinder turns perfectly coaxially with the shank. Even a very small displacement in the direction of the workpiece cause the cylinder to "kick off" and displace dramatically along the workpiece edge.
