Alignment and final drilling
9.0 hours
 |
| Forward plumb bob (Full size) I created plumb bobs from sockets and fishing line. This allows me to make sure the assembly is vertical from front to back before drilling the j-stiffeners |
 |
| Another plumb bob (Full size) The next one back |
 |
| Line it up with the centerline (Full size) Making sure it is correct. |
 |
| The final plumb bob (Full size) This one is at the end of the tailcone. |
 |
| Final drilling j-stiffeners (Full size) Now that everything is lined up, drill the stiffeners and cleco. After this the assembly is much more rigid. |
