I've not tried the other brands but after tonight's session I can give the Oneway Stronghold a ton of praise.
I was working on a very large piece (and grossly underestimated the weight).
So the foot was mounted in the chuck (5" jaws) and also held by my steady rest as I was hollowing it out.
After about few hours, I heard 2 loud bangs - I thought they sounded like electrical shorts, but couldn't figure out what happened.
It did smell weird but everything seemed fine.... So I kept turning.
20 min later I started getting more vibration and wobble. At that point I realized that the lower rollers on the steady rest had exploded and disintegrated!
The whole thing was being up held by the chuck!!!
Ok, so that to be expected right?
Well.....after replacing the wheels 2 more times, I finishing roughing the piece in, took it off, and found out it still weighed well over 80 lbs.
So when the wheels failed it was way over 200 lbs and 24" tall!!!
And chuck held it just fine.
All I can say, is that I'm now very grateful to Oneway for making an awesome product.
I shudder to think what would have happened if that thing had come loose at 300 rpm.
