By the way, they were of high quality as airlina stated and fit and worked great for my wings. Unfortunately I don't have any photos but can take some in early April if you need them.

I also used the stainless spar inserts on my 5 and was very happy with them.

I wish they were still available. I guess I am just going to put two steel plates on the inside and 2 on the outside. I'm thinking I will go with ss rivets because that is what was in it. Can someone give me a link to the ones on aircraft spruce I need. I don't see where they say anything about "structural" I'm just nervous I will get the wrong thing and my wings will fly off. It looks like 2 .0625 plates and .049 aluminum wall thickness of the spar which is .174 plus hysol and micro balloons. I know there haven't been any issues with this setup but it just seems crazy my life is depending on pop rivets!
Why not just buy the plates and proper rivets from Kitfox? The plates come preformed to the radius of the spar tube. We need to support our manufacturer plus get the right stuff.

Because my stuff I have on order is still not here after a month.
20180219_112019.jpg So I bought certified 4130 chromoly plate, built a die to bend a blank and made this. I copied the original steel doubler with the exception of making it wider in the rear to accommodate adding 4 more ss rivets. That way I can hopefully try to get the original 4 rivet holes lined up but if they aren't perfect have 4 new ones that will be right on because I will drill them with the plate attached. Do you guys agree with all this or have anything to add?
I think that looks very good, Brandon. Nice job. Is your 4130 material annealed, or condition N (normalized)?

It appears that it is annealed. Is that what I want?

There is a big difference in strength between the āAā and the āNā conditions. You can bring the annealed to a normalized state by heat treating & quenching. I am not sure what Kitfox specifies & uses for these pieces. Condition N is the standard for most 4130 used on aircraft.
