The style pizza cutter I have used, looks more like a machete (friends restaurant), so I don't have a round one to try. That said the SVD-185 has a jig with it for smaller turning cutters and I am wondering if that could be used with larger wheels like the pizza wheel? (certainly not as large/awkward or dangerous as the slicer blade from another thread)
If not, while spacing would have to be figured out (is the bar long enough to get back far enough) you could use a dowel with a screw in the end, to hold the blade.
