January 22, 2005 - Right Flap |
||||||
| Once all the match-drilling of the flap was done, I took it apart for the standard prep work: deburring, dimpling, countersinking and priming. I'm dimpling the spar here. Notice the snow outside and the EAA T-shirt. . | ||||||

Another rare dimpling action shot.

Because of the Hinge, the bottom's a little different. You dimple the skin, countersink the spar and do nothing except deburr the Hinge. When countersinking the spar, I had the Hinge clecoed underneath to act as a guide for the countersink bit. |

| The next step was to rivet the
reinforcer to the spar. First I had to prime the reinforcers.
This was a problem since it was less than 20 degrees outside. I waited
until the afternoon when it was as warm as it was going to get, sprayed one
side of the reinforcers with the Mar-Hyde, then brought them inside as soon
as they were dry enough to touch. After they had warmed back up, I
took them outside again, and sprayed the other side. I was pleasantly
surprised when the priming seemed to have come out fine -- no adverse
effects from the cold.
In the picture, I'm in the process of riveting the reinforcer to the spar. |

| You can't really see here, but I have riveted the rib ends to the "virtual" rear spar. I was able to do it using the hand-squeezer. | ||||||
