To positioning the remainig 5 corners just change the 'old Workbench' and use this 'new Workbench' instead.
The change of the 'workbench' will affect the 4 cubies already sorted on the White face: OWB, WB, RW, RWG, and the edge RB on the second layer. But at the end, every thing will be automatically sorted correctly by the cube itself.
The overall strategy is straightforward: swap the corners in the rdf and ruf positions by employing the 'sledgehammer' (R F' R' F)
There can be 3 cases:
In this case, the final result is the cube fully solved. It is not impossible, but it is rare.
The result of this 2 cases ('easy' and 'standard') is what normally happen.

Brings the RYG onto its final position- The rotation U brings the destination onto the 'Workbench'- The 'Sledgehammer' moves the RYG to its final position |

Brings the RYB onto its final position- The rotation U' brings the destination onto the 'Workbench'- The 1st 'Sledgehammer' moves the RYB to its final position - The next 2 'Sledgehammers' adjust the orientation of the cubie RYB |
| 3) | 2 |
The cubie OYB needs just to adjust its orientation- The rotation U' brings the destination onto the 'Workbench'- The 2 'Sledgehammers' adjust the orientation of the cubie OYB |

Restores the 'new Workbench'- The 3rd layer is complete, and the rotation U' brings all the cubies into their correct position.- The 'new Workbench' is totally messed up. To restore all its cubie, just keep repeating the 'sledgehammer' until the cube is solved or all the cubies inside the 'new Workbench' are in their correct places (2 times in this case). It frequently happens that cubies at the position destination and destination are correctly placed but with the wrong orientation. This case (very common) will be analyzed in the next session. |

The 'sledgehammer' (R F' R' F) would be sufficient to solve this step. In some cases, however, it may be necessary to execute it more than three times in a row. In such cases, it is advisable to use its 'reverse' (F' R F R') Due to the cyclicity property, 5 iterations of the first sledgehammer are equivalent to a single rotation of its reverse. (Refer to Cycle for more information.)
