Last time I tried one of these, I warped the drive shaft so badly the saw was entirely unusable ever again. And that was a brand-new demo unit put on the floor specifically to show it off. I'll take my chances and use the time-tested method of using a custom-built wooden jig to hold the piece while it goes through the blade.
