January 11, 2006 - Dimpling & Countersinking |
||||||
| I had forgotten to dimple the sides of the bottom skin so I did that. I also drilled some 7/16" holes for the fuel vents. | ||||||
 |
||||||
|
I'm still not done with the countersinking! I had to countersink
the two F-704 bulkhead side braces.
|
||||||
 |
||||||
| I deburred and dimpled the firewall. You may recall that the firewall is stainless steel. It deburred fine, I just had to use the deburring tool more forcefully than with aluminum. | ||||||
 |
||||||
|
Joe and I dimpled the non-edge holes of bottom skin with the C-frame and
it was done.
|
||||||
 |
||||||
| Lynnette and I dimpled the non-edge holes of the side skins with the C-frame. That looks suspiciously like an "RV grin". | ||||||
 |
||||||
| Can you believe it? Still more countersinking. This time it's the bottom reinforcing angle of the firewall. After countersinking hundreds of holes, what's another 50 or so? | ||||||
