I thought shimming the spacers, but it occurred to me that this may result in the spacers being “canted” on the spindle carriage. After shimming, the v wheels would sit at different ZX planes and placing them on the maker slide would force them to be in the same ZX plane. The only way for this to happen would be tilting/twisting of the v wheel mount and spacer. This seemed liked it would be less stable and increase wear. I’m probably overthinking it though.
