Assuming the brute force way works and I don't need to reduce gantry height, then my problem is how to deal with the greatly increased distance (10cm) from tool tip to bed (I moved the spindle up in its brace to reduce vibration)? I can't find any clamps that can go that high. So that was the other motivation for reducing gantry height.
yes, I've figured that out the hard way after snapping several end mills
