Thanks for this Doug, when i sharpen Skews i have it set on the top hole at 15° i see you are using the 30° is this due to the curve of your skew??
If I'm honest Jim I don't know what angle it's set at, it's the bottom hole of the front row of holes which when I shaped it looked about the right angle I was looking for, particularly as I wanted to use it for scraping.
That said I don't think you'd have a problem if you altered the angle you're only pivoting the chisel whilst holding it down on the tool rest, best bet is to try it without the machine running, just get used to moving the edge across the belt before you try it with the pro edge running.
