The support blocks looked ok at first, although I wanted them to be fully threaded. When I first started trying and using these threaded holes, they weren't straight. I had a screw hole that was machined about 10 degrees. I could handle crappy bearings if the pedestals were ok. But that's junk. Pillows are bad, bearings in them are bad. Only one bearing was in good condition. One has bearings that barely move and the other two have a bearing that doesn't seem to touch the smooth bar at all. At first I only gave them three stars because I thought the pillows were ok but they weren't so I downgraded the review rating to one star.
