I was wondering someone could clarify some things for me. On the alpha, it seems like the 4 outer angled supports can't move or be locked in to place? For example, on the gamma progression II 606FC, the outer angled supports can have their angle adjusted to fit the frame squarely, and then be locked in place. Is this not the case on the alpha machine? Also, the gamma supports seemed padded but the alpha does not? Lastly, I believe on the alpha, the clamps are diamond dusted, but the ratchet gripper is not? Is this an issue? Thank you in advance for any clarification.
