The first job of the day was to sort the funny shaped hole for the pitot mount. I started by using the hole drills to get points at both ends of the shape. |
|
Then it was "scary tool #2" - the rotary burr. This got the shape pretty close. |
|
Then it was back to the old fashioned file and scotchbrite pads. |
|
The finished product ended up really neat and tidy. More parts for the priming pile. |
|
Then I riveted the nutplates onto the pitot mount. |
|
The FIRST completed sub-assembly of the project, not quite the normal VANs order but never mind.... |
|
Next I riveted the Horz Stab central bearing, this is normally the first assembly to be built. |
|
I found the AD4-5 rivets suggested too small and used AD4-6 for 4 of the 6 holes. |
|
Next up was the aileron mount brackets. What I hadn't worked out was some of the rivet should be AN426's (countersunk) so I ended up having to drill after priming. |
|
The brackets cleco'd ready for riveting (the rivets are top left of the drawing). |
|
The riveting needed the longeron yoke to get the maximum travel for the AD4-11 length rivets. |
|
The finished brackets ready for the wing trailing edge. |
|
Meanwhile during the day Dad deburred and sorted the RHS lower skin. |
|
We also completed the dimpling of the lower skin and finished the edges. |
|
The skin and pitot mount cleco'd back onto the wing structure for safe storage. |
