Better than expected

I opened it up to remove the expected sand and it was spotless. Fat but no oil. At the very end of the spindle, the rotating part, there was a drop of grease. Still gets 5 stars. i have oil

Great deal for the price!

I was really surprised by the accuracy. Usually the Chinese stuff I get is absolute rubbish but at only $25 for the MT3 version I decided to give it a try. My old American lathe worked fine on a large lathe, but is too big for my imported lathe. I'm almost ready to turn a cone on an imported lathe and without a tailstock the cone is usually 10-15 (0.010-0.015) thousandths, but with this driven tip I've reduced it to 8 tenths (0.0008) what easy to explain is misaligned guides or insufficient…

  • Perfect for outdoor activities
  • Unbelievable price

Ultra high precision, no bounce

This live hub is a great deal. I use it for turning. I used a Mitutoyo dial gauge with a sensitivity of 0.0001 inch per step to measure the run out at the end and the run out was only 1/4 to 1/3 of a 0.0001 inch step i.e. the measured one Runout was about 0.00003 inch or about 3/100,000 inch. This is ten times more accurate than the claimed concentricity of 0.0003. It does NOT have a carbide tip as stated in Revain's product description. There are no solder joints to be seen. You can see this…
