Canopy Components – Part 2
Took SNB-D03-09L and updrilled holes per plans; inside holes to 3/16″ and outside holes to 13/64″ to be tapped. Countersunk 3/16″ holes for flush screws and tapped outside holes with 1/4″-28 tap set for canopy alignment pins. Hours Worked: 0.64
Control Stick Assembly – Part 3
Disassembled dual stick assembly and deburred stick holes. Lubricated control stick horns with lithium grease and deburred taper pin holes. Reassembled left and right control sticks and attached link rod with hardware. C04 complete! Hours Worked: 0.70
Canopy Components – Part 1
Began canopy/windshield frame prep by working on canopy forward aft bows and windshield bow. For canopy bows, started by countersinking bow holes for -6 flush rivets. Riveted components together using -6 solid rivets. Laid out bows on workbench and marked centerline on bows. Measured out pilot hole locations for attach screws per plans and pilot…
Control Stick Assembly – Part 2
Set bushings into top of control stick frame with Loctite 638. Using new taper reamer, reamed LH stick grip hole and inserted taper pin. Repeated whole process for right hand stick grip and found that sticks were not parallel with control horns and cross link tube would not fit in between left and right control…
Control Stick Assembly – Part 1
Began control stick assembly process by drilling 1/8″ pilot holes in bottom of stick grips. Removed powder coating from shaft of control stick horns by using heat, sandpaper, and scotchbrite wheel. Installed SF-2024-8 bushings into control stick frame; fit is okay but will need to put some Loctite 638 on bushings to ensure they do…
Fuselage Final Riveting – Part 1
Drilled holes through spar bumpers then riveted to fuselage with spars in place. Clecoed fuselage floor into place to check fitment with all holes aligning. Transferred pilot holes from floor into bottom of forward spar tunnel assembly then updrilled to #30 and clecoed into place. Hours Worked: 1.85
Wing Rigging – Part 4
Removed rear spar carry through from fuselage then updrilled attach angle holes through fuselage. Removed attach angles from fuselage then deburred rear spar carry through, shear web, and attach angles. Finished riveting rear spar carry through then riveted shear web onto carry through. Placed assembly back into fuselage and clecoed into place with spars pinned…
Wing Root Doublers – Part 2
Measured wing root doubler trim distances off of wing skin at each rivet hole and transferred measurements onto inside edge of wing root doublers. Trimmed excess material off with snips then deburred edges. Clecoed wing root doublers onto wing and verified clearance from fuselage sides was between 1/32″ and 1/16″. Hours Worked: 1.89
Wing Root Doublers – Part 1
Slid wings out from fuselage (one at a time) and reinstalled wing root doublers with clecoes. Marked current edge of doublers onto wing skins with sharpie. Removed doublers then slid wings back into spar tunnel and pinned into proper place. Set wing doublers onto wings and slid them flush with fuselage side skins. Marked a…
Wing Root Electrical Connectors
Removed rigging hardware from main wing spars through the three center holes in the spar webs. Slid RH wing out slightly for better access to fuselage side. Located wing root electrical connector and cut out hole for pass through. Drilled mounting holes then used 8-32 screws to attach bulkhead connector to fuselage side. Measured out…
Wing Rigging – Part 3
Finished drilling main wing attach holes by using drill guide to drill 3/8″ holes in forward wing attach angles (from back to front) then updrilling each side to 1/2″. Wing pins fit it snug and wings do not wiggle on fuselage. Realized rear spar carry through was installed backwards so flipped it and made temporary…
Wing Rigging – Part 2
Began wing rigging process by inserting RH wing into spar box then inserting LH wing. Supported wing tips with saw horses while trying to align the three rigging holes between the two spars. Process went much easier with three people: one on each wing tip and one person inserting bolts. After bolts were inserted into…
