The blunt face of the Powermatic 3520B has not been a real problem since the bowl is usually held in a chuck when holding the bottom. I did buy the 1-1/2" extension (about 2" by memory) when I purchased my lathe and have use it on occasion to extend shaft to jam against bottom which would be about same as the long taper snout of other lathes. That would not be the decision maker for me.
