Starrett Wiggler/Center Finder

Starrett Wiggler/Center Finder

Wiggler/Center Finder No. S828 and three different attachments adapt to countless
applications and are readily interchangeable. The attachments are snapped in the chuck without removing the collet nut and are clamped by a ball swiveljoint which permits adjustment to an angular position or true concentricity.
With Pointed Shank No. 828A, working centers can be quickly and accurately
located. Spring tension on the ball of the point permits guiding the point to true
concentricity so that the work can be brought into perfect alignment with the machine spindle.
Ball Contact No. 828B is useful in locating work by first bringing the contact (ball diameter .250" or 6.35mm) against the work, a slot, hole, shoulder, or end, and
indexing the work to the desired position
relative to the spindle.
Disc Contact No. 828C, which has a small disc at the end (.100"/2.54mm) diameter,
permits use in more confined areas such as slots or shallow holes.
