Using the pneumatic squeezer outfitted with #30 120 degree dimple dies to dimple one of the twelve W-1275 corner skins.
Dimpling one of the W-1274 corner skins for
flush rivets.
Looking forward in the plans, there were only two
other components that required attention before all the major components in Sections
20 & 21 would be processed. Decided to move forward and finish up the two pieces so all the components will be ready to go. The W-1236 step attach angle came predrilled
on one side but required being separated into four pieces. After the four parts
were separated, they were deburred and marked for additional cutting. The plans call for cutting off an edge of the
un-drilled side of the angle. The pieces were marked at 1” per the plans, run
through the band saw and deburred on the Scotch-Brite wheel.
Using the band saw to separate the four W-1236
step attach angles.
The last piece prepared to comple all the components for section 21 was the F-1251-L&R nutplate brackets. Here
again, the brackets came as one piece and required separation on the band saw
followed by a smoothing on the Scotch-Brite wheel. The plans also called for
machine countersinking the #40 rivet holes for the nutplates.
Using the countersink cage outfitted with a #40-100
degree bit to countersink
the nutplate rivet holes in the W-1251-L&R nutplate
bracket.
The F-1251-L&R nutplate brackets and the
F-1236 step attach angles complete the parts preparation for section 21.
The last batch of parts worked on the last few
days will be cleaned with Acetone, scuffed up with Scotch-Brite pads and primed.
The weather forecast is for a perfect painting day tomorrow so will try to make
the most of it and get things primed early and perhaps also spray a little more
Jet-Flex if all goes well.
Parts prepared the last few days now ready for
the DOG Aviation paint department to cleaning and primer.
