Don't assume that this mount will absolutely orthogonal. That's totally
dependent on the quality of the machining. I don't see any advantages
to this design which would make it inherently easier to machine it
orthogonal, and in reality, it's precision is probably no better than a
Giro-2. However, attaching encoders to the Giro, might be a bit
difficult.
