Advanced really needs to work on their website. All they show is the front view and they give no information other than it's a 1" shaft. Looking at the pictures some of the wider rests have a support welded to it that would impact how much the tool can be tilted down. Without a side profile view it's hard to tell. They say they will make the rest to the right height for your lathe so I assume that they must build them after you order one. It would be nice to see them in person. One of the hardest things with owning a lathe is not ending up with a lot of extra stuff that collect dust because you don't use them. In the long run it's not so much of a problem (as long as you know you have it) but most of us try to stay within a budget which means trying to pick the stuff that will be of more use. I can see having 3 or 4 rests (probably a couple made by me specifically for my needs) down the road but I would rather focus on being able to do segmented bowls and hollow vessels.
