Alignment and final drilling
|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.
