That's good to hear about the UA9 wand BeEvil. I think many people had the UA7 wands on the UA9 but not the other way around.
As far as mounting the WE-308, I am looking at the manuals and don't see the angles to go with the 235mm pivot to spindle distance. Are 30 deg. at the spindle(to the horizontal) and 60 deg. at the pivot(to the vertical) common angles that I can use to locate my arm board hole? Without the template, if I swing a 235mm arc from the spindle, across the arm board, what other data point will locate the hole along that arc on the arm board? Probably something easy that I am missing...
