Carter has 2 hollowing systems and I have the smaller version with all the different size bars, cutters, laser....the whole 9 yards. Works fine for me and the type of hollowing I do with wide mouth vases. I can get a good 12" deep with the 1" bar before it get too much chatter. Just made a front tool rest that allows me to get the bar supported inside the vase but haven't been able to try it out yet. Get a Hunter cutter and you can hog like a wild man. Some people don't like it for side to side movements but you can loosen up the capture roller if that becomes an issue. Been a good performer for me.
