8-21: Tailcone Bulkheads

Build Crew:

Hours:

James	1.3
Nico	2.5

It’s a goofy photo of Nico, but it really represents all the work we did prepping for the tailcone bulkheads. These bulkheads will maintain the shape of the tailcone structure and provide the strength to attach the horizontal and vertical stabilizers. See below if you’re still not sure what I’m talking about.

There was quite a bit of fabrication, drilling, deburring, and even some dimpling but nothing too complicated. Below is an album of photos over a couple sessions (with James and Nico helping!)

James separating and fabricating doublers and reinforcements for the stablizers.

The bulkhead flanges required bending to match the contour of the skin angles.

Precise measurement for attaching the WD-409. Unfortunately it is STILL backordered! I’ll move out without it for now.

keeping track of similar parts requires some labeling and noticing the nuanced differences. Here is a before and after cutout of the F-811 bulkhead parts

The vertical bars were thick enough that cutting oil was in order.

F-811 Bulkhead assembly will do much of the stabilizer support and connection

some precision cutting of excess and unneeded tabs

… including some dimpling and countersinking.

The bulkheads are all prepped and ready for priming. I should be able to tackle that in the next session. Until then… Happy Building!
