Review on 🔍 Starrett 50074 C11-1224 Center Head: Optimal Precision with the Starrett Comb Square Head by Michael Robertson

As with any Starrett instrument, this is a quality instrument. Will be mailed in an envelope with a standard Starrett box. I think the price is fair for what it is. From time to time you will need to check and adjust the center head. You can check the accuracy of the centering head by taking a machined disc and placing the centering head on the disc as usual. You then mark where the ruler is and then rotate the center head 180 degrees. If both lines match, the centering head is accurate, otherwise it needs adjustment. You can adjust the center head by sanding one side a little and checking the disc again until both sides of the center head align.
