Wing and tail mounting hardware questions

[jiott]

Yes, I hear that the manual keeps improving over the years. I can only speak to the SS7 manual which in my opinion is excellent. A torque value for nearly every bolt is given; however, for the few that are not individually called out, the manual says to use the standard torque tables given, I believe, in the "Builder's Tips" section. Its good that you are trying to find the correct info. I know a guy who was just winging it and actually broke a bolt from overtorque in a critical area. Its a good thing the bolt actually broke so he could replace it, rather than an invisible overstress that would break later.

I walked out to the barn and measured all the hardware and ordered from Spruce. What I found comparing what I measured and what the book calls out is strange. If the book called for AN3-4A, I measured -7A. They were all that way, slightly longer. I may to go back out to take another look to see if the builder doubled up on washers. I was having a hard time in a dark barn with reading glasses trying to fall off my face with a ruler in one hand and a flashlight in the other. All I was interested in was grip length, didn't pay too much attention to the washers.

I know what you mean about the hard times!

That would be a lot of washers. If you use a bolt that is one grip length longer it takes 2 normal washers to fill the gap.

I know, and it didn't look like there was a stack of washers on every bolt. I'm hoping I get the chance to work on her this weekend. I need to move the Jeep and unfold the wings so I can get a better look.
