I’ve been at a little bit of dilemmna the last few days trying to figure out what direction to take with the project.
I still have the left rear spar to work on (until the left main spar shows up from Van’s…shipped yesterday…should be here Wednesday), or, I could move ahead with some rib prep on the right wing.
For the sake of seeing something cool at the end of the day, I think I’ll move ahead with the right wing, and hopefully I’ll be able to get it onto a wing stand (yet to be designed) by the time I can get the left spar caught up to this point.
With rib prep, I’ve decided not to follow the suggestion to do all the ribs at once. I’m going to do them a few at a time to save my sanity.
First thing, let’s find some ribs.
Notice here that of the three different kinds of main wing ribs, there are both left and right versions in each of the wings. From what I can tell, the flanges face left or right based on what will be easiest/accessible to rivet.
My goal today was to get the ribs clecoed to the spars, so I’m only going to finish what I have to (out of efficiency, not laziness). This means I’m going to edge finish most of each rib, then move on to fluting and flange straightening.
The edge finishing (except the little crevices) only took about 30 minutes on the sanity-saving scotchbrite wheel.
The fluting and flange straightening took 2 more hours, though. Ugh.
I took all 14 right main ribs inside and watched the UNC-GT and the Vandy-Ole Miss games.
After a little while, my hands were hurting from all the fluting, so I took a picture of what I have done so far.
And after another couple of hours, I had the main ribs edge-finished, fluted, and flange-straightened enough to cleco them to the spars.
I really didn’t think I’d get this far tonight. (I have to keep in mind there is still a lot more prep on the ribs before I can actually prime them and get them riveted to the spars.
And of course, here is the obligatory “down the lightening” holes shot.
But that’s not all! I have variations on a theme.
After sending the dogs back inside for their Saturday afternoon nap, I just stared at this thing for awhile.
3.0 hours today.
