This is not a high precision device, mechanism is sloppy which causes the dial gauge to be all over the place. Like finding your way in the dark without a flashlight. Read more

Not worth the price for something that doesn't work as intended. Dial indicator works great, but when attached to tool you can not get an accurate measurement for ring filing. Depending on where you have your ring at on your grinding wheel will change the dial indicator zero point. Therefor you will never get knowledge of how much you take off the ring.. Recommend doing it by hand with a hand held device. This takes off way to much at a time. Read more

This is a nice tool for the money, instructions are basically useless for any novice, not even a schematic to see where parts that have vibrated loose in shipping go. As far as the tool it's actually really cool, a lot of details in the build. For me, the handle that moves the ring holder was way too loose,,,very sloppy, I machined .005 off of the shoulder bolt that holds it on & it now works smoothly & without any jankey action. I did add a pushback spring (siliconed on) to move the ring holder back automatically,. easy fix. All in all worth the dough. Read more
