Much of my machine shop work involves making a tool for a specific application, and no machine is known to exist for such. So I work with my customer to determine what is needed, and through brainstorming and sketching, testing, etc, we can come up with a machine to fill the requirement.
The Band Gage
The machine below is what I have termed a “Band Gage”. It is used to measure the circumference of parts to compare their diameters with a known ‘master’ diameter. If your molded parts need to stay within certain specifications, this machine will help you determine which parts fall within specifications, and those that do not.
The band is a thin steel strip which surrounds the part, and is tightened on the part with the red handle on the left of the picture.
