Review on High Precision HFS Coaxial Centering Indicator by Scott Morris

Media could not be loaded. I was hoping to use this to identify the cylinders when installed on my lathe, but a quick test showed that would not be the case, so I would have to send them back. In the video I have attached a standard piece of brass where you can see the rough surface of the shank and even a cheap dial indicator with a runout of 0.003+. I know the longer the lever used on the coax the less deflection it shows, but on a medium length lever it doesn't register even 0.003 runout making it impossible to set anything accurately. I got tired of turning it by hand and couldn't read anything. I also tried preloading the arm light/medium and heavy, but it still didn't show anything with a surface area of 0.003 or less outside of the round shape. If you're just using it to get something close, and it doesn't matter if you deviate that much, then I'm sure it's fine, but it won't cause the finished surface to go into the Center is chosen what are you looking for.
