Ah, where to start... by necessity this will a bit disjointed but everyone will leave happy. It started years earlier, but seemed to gain a focus when I started playing on-line poker for pennies. One doesn't control
the cards one gets; but I do have control over how much money I lose. So after a time, I started asking "where' is my money leaking from?" (I didn't really end with a prepoposition) and it became clear that I just wasn't
seeing things going on around me. I"d have three aces and focus on betting only to get beat by a better hand. "Where did that flush come from?", "Hey, why didn't I see that straight?" . The point being something can be
happening right in front of me and I won't see it.
So, back to my rib repair. Lots of valuable suggestions on how to repair the ripped web from the group, but the final judge is my IA, so I visited him at noon yesterday. He looked at the rib.

He turned over the rib. (first picture)

He pointed out the cavity thru which I could work and he described a very simple patch (template shown in second picture)
which he would allow to be held in place with 2 1/2 rows of CherryMax rivets (since I have solid rivets and my gun is a day or two away from arriving, I think I'll stick with solid rivets). The dotted lines are where the rivets will go; I plan on substituting aluminium sheet for the 3x5 card stock.
Second bit of excitement. I'm still not happy with my rosette weld and my splice by inner sleeve. Called Dillsburg to order some inner sleeve material, explained what I was going to practice and Mr. Vogelsong launches into
one of his much appreciated lectures. Seriously. I get more from his lectures than the cost of the order! In this case he explained 11/16" 4130 tubing was not a good seller and would not stock it anymore. I asked what we'd do in that case and he began explaining rosette welds . I mentioned the problem I was having i.e. an 1/8" hole in the outer sleeve wasn't enough and would
burn away well before the inner sleeve got molten. "So, make it 1/4" or even 3/8" in diameter - You're going to melt it all back together". Then I said "You know, that's exactly the same solution for the problem I'm having with my welding inner sleeves. I'll open the gap to 1/4" ( from 1/8) and see if I get the penetration I need."
If that works, that will be the solution to my landing gear repair which has been languishing for a year.
Amazing - I can read, I can practice until I'm blue in the face and a telephone call to a guy who likes to talk saves me 1/2 year of work!
Of course, there is a hurricane and accompaning rains bearing down on us at the moment so I can't practice. I know, I'll finish off the sheetmetal on the ailerons (after removing the bow tube at the tip ; just realized I didn't linseed oil their insides)
