Priming and assembly
Hours: 10.2 | Posted in Cabin & InteriorPrimed the roll bar components and other misc bits from yesterday’s prep session. Also deburred , etched, primed and dimpled the top skins and J-stringers, since they need to be in place for the roll bar fitting, to hold everything at it’s proper location. I have not painted the roll bar parts yet, since there is still some fitting to do; I will paint it as an assembly in the next batch after fitting, along with the channel that holds it in place.
Once the primer was dry, the roll bar was riveted together, then the brackets were clamped, drilled, and riveted together, then fit and drilled to the fuselage. Spacers were fabricated from .063 stock to go outboard of the brackets (yes, the angles are supposed to overhang the fuselage and be filed, but my roll bar ended up a bit narrower than expected, and this will actually work well to allow a gap for gluing the forward line of the rear window to the roll bar). That is not a fun filing job.
With all that out of the way, I riveted in the 709 bulkhead and the top rib behind the baggage compartment, and clecoed on the top skins in preparation for tomorrow’s work. I drilled the two holes from the top skin into the roll bar brackets and spacers at #40 for now.
