SPI - Zero-Set For Test Indicator
- "Zero-Set" is specially designed for test indicators with dovetails and functions as a quick and practical work positioning device
- Setting up a workpiece before machining, or aligning the center of a round workpiece in relation to the cutting head, takes virtually no time with "Zero-Set"
- Attach "Zero-Set" directly to the collet, then zero-in the work position by reading the test indicator
- The hardened clamping post consists of three O.D.'s, from top, 1/4", 3/8" and 1/2" and has hardness of approximately 58 to 60 RC
- The illustration indicates the alignment of a workpiece in relation to the cutting head
- It reaches anywhere within a 8" diameter and fine-adjusts about 3/8" with a large knurled knob
- "Zero-Set" can also be adapted to transfer stands for closer control of the test indicator (in the horizontal direction)
- "Zero-Set" attachment allows for the placement of any test indicator equipped with dovetails or 1/4" posts in a multitude of positions and angles up to 90 degrees on either side, bending both forward and backward
