I have no direct experience with this, but there are a lot of users online who either have the Incra positioner or a DRO to set width of cut on tablesaws (not just Shopsmith's). In the online forums I have visited and reviews I have read, those users rave about using them for setting precise and repeatable widths for tablesaw cuts. Again, I have no direct experience with either, but I think both offer the ability to zero (calibrate) to the sawblade. I am sure there is some learning curve with this, e.g. how close do you get the fence to the outer tooth on the blade. Might have to fine tune a 32nd one direction or the other after making a test cut, but once that is known it should be bulletproof. I don't think I would be seeing so many glowing reviews of Incra or DRO's if this wasn't the case. Understandably some of this could be marketing BS to sell the tools, but I think I have seen enough posts in forums from what appear to be actual users of the tool.
