Hull Modeling in the flesh: part 1
CNC cutting parts for a quarter scale model
 |
| The 3D computer model is sliced up into sections that become molds for defining the hull shape. |
 |
| You can see the molds formed now, trimmed to the hull surface, and one more to go! |
 |
| The hull is planked and ready to be broken up into the "flat" 2D geometry. |
 |
| A neat screenshot that shows the 3D and 2D nature of the work: in the foreground is the 3D hull model. In the background is the geometry flattened onto the "construction plane". |
 |
| This is the file with the 2D geometry as received by the CNC cutter, CNC Routing & Design in Camden, Maine. Tim will load the file into his Shopbot software, make toolpaths, and cut the parts. |
 |
| The ShopBot machine cuts to my lines with a couple thousands of an inch accuracy. These are the planks of the boat, the bottom keel plank in the center and the sheer strake to the far right and left. |
 |
| The molds of my quarter scale kit around which the planks will be wrapped and checked for fairness and for fit. |
