As pointed out yesterday by the fabricator I am working with (Quantum Bicycles in Perth - I don't have a shop and they really know what they are doing).
With the Grin v7, there are two pinch bolts to provide serious compression on the axle clamp. The comment is to tighten them progressively - a bit of one, then the other, alternating. Tightening one first before the other can tilt the clamping pad causing it to jam in the channel well before it's tightened enough to provide enough clamping force. He even suggested working up to the full 12 N-m final bolt torque to avoid this - 2 - 4 - 6 etc. to avoid jamming.
