Build Log 02 Gantry 2010 |
||
|
Right: well, you see . . . |
||
|
Right: the end frames and bearing rail boxes are fab'd first and then mocked into place, leveled, squared, and whatever other kind of straightening we can possibly think of and set. |
||
|
Right: The fix for the cantilever stress on the bearings is to flip the lower part of the gantry uprights so that the center of gravity is effectively moved back toward the center of the front & rear bearing blocks of the gantry uprights. Here you can see the cuts made just below the connection point for the horizontal trapezoidal truss of the gantry so that the lower portions can be flipped (swap left & right sides) |
||
|
Right: Here you can see the "flipped" lower gantry trussed uprights which re-sets the center of gravity for better stability. |
||
|
Right: after the cut, just prior to flipping the lower gantry uprights. |

|
Right: Rhino working Model with "flipped" gantry uprights. |

|
Right: The frames cut just before re-welding in flipped position. |
