Vector 40 kit build
kevin king:
Ok, who has built a Brodak Vector 40 KIT that can answer a few questions? If someone could tell me the height of the rib centerline off the table it would be helpful. So far I did my best to flatten and shim the table. Then I pinned the 1/2" balsa Leveling bar to the plans and checked it with a ruler, next I shaped the wing lower spar and shimmed the tips up 1/8" off the table. Then I dropped the ribs in place on the spar. Well, if you have built this kit you know the slot in the ribs has to be opened up to fit the spar. Long story short all the center lines are OFF. Note: This is a die cut kit, not a laser cut kit.

HB~> The rib center lines from the front to back are off as much as an 1/8" on each rib. And they are off in a random matter. I hate building wings. I guess I should have checked each individual rib before I glued it. Thats why I need the center line height off the table.

Guess I will bust every rib off and re glue them.
kevin king:
Motorman, the spar slots needed some sanding, to fit on to the spar. That is possibly the reason the ribs were out of alignment. So, in other words, the center line of all the ribs are off. I see no other way to fix this except breaking each rib free and aligning them one by one. Something I should have done in the beginning before gluing them all in place with CA.
