Just throwing this out there - when your shafts arrived, were they left outside in the cold before opening? The tolerance is so close that a shaft below room temperature will smoothly fit, but they will be too tight if you don't do that.

Anyhow, for us it's now a standard practice to take some emory cloth and shaft stock and run it on the lathe for a second or two before fitting into bearings. Just enough to strip the anodize layer off should do it. (We also use the "tight press" bearings because they are so cheap in 11-packs)

ThunderHex is way, way, way better than regular hex. I'll never go back to regular hex bearings - they are a pain to fit, a pain to align, and they are far harder to fix the shaft for if they fit too tightly.
