Thread: Concentricity Gauges

Hi all
I bought a Sinclair from the states because I wanted quality from one of the companies that originally made them.
It arrived in a week after ordering, was unpacking and it looked and worked great and when I went to put back into the box saw “Made in China”. Apparently Sinclair must be owned by Chinese. It was half the cost of getting the same item through H&F, however it does work well and I have checked it against an engineers proper instrument. I mainly use Lee collet dies and invariably get below .001 runout.
