Rear spar assembly
4.0 hours
 |
| 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. |
