Title says it all.
Anyone care to share the pros or cons and/or likes or dislikes of the one you've bought?
I see a couple of styles on eBay occasionally and am seriously in the market for one. One style loosens the bolts and make vertical adjustment, the other appears to be sitting on a wedge that you adjust back and forth to raise or lower the vertical height of the center.
I suppose it doesn't matter once the height is matched to the rotary table and is set, but how about issues of lining up with the axis of the rotary table as you move the tailstock closer or farther away? Is one model better than another for ease?
