This is a very strong, well built piece. The only downside I have, and it's a small one, is that the body(?) is quite large in diameter, which limits caliper/linkage positioning on shorter projects.
Good fit MT3, has ball bearing lube. Was a bit worried when I got it as I couldn't rotate the center by hand, but once I used it I let go of whatever was sticky and now it can be rotated smoothly and easily by hand.
This Live Center rocks! It has great bearings, great design and will likely outlive its owner. I use it at Wheat State Welding LLC's commercial shop in Derby, Kansas. It is very accurate with very little total stroke displayed. The only thing I would like is a bit on the back so you can remove it from the tailstock by pulling the tailstock all the way back. I think you could cut some threads on the back because there's a hole that's almost a perfect size for a 3/8 thread and put a screw inβ¦
