Rear spar assembly
|Final drilling inner rear spar doublers (Full size)|
First thing was to file and deburr the rear-spar and all doublers. I was missing the outer doubler, so I ordered it from Van's. Here are the inner doubler's cleco'd into place. Next step was to drill em to final size
|Middle doubler (Full size)|
This doubler is clamped into place for drilling. Also it needs the aileron pushrod hole opened up.
|Primed rear-spar parts (Full size)|
After the drilling and deburring, several holes need countersinking in the inner doubler. After that, cleaned and primed.
|Assembling rear spar (Full size)|
Cleco'd together the inner spar doublers and riveted with the hand-squeezer. Many of the holes will be riveted later with various other parts so they remain empty.
|Assembling rear spar - middle (Full size)|
Here is the middle doubler in place. Most of the rivets come later.
