Since there are not many 801 builders out there I kind of feel all alone. Poor me. I imagine this question applies to all the other designs too. I am about to rivet on the leading edge wing skin on the right wing. I have pulled it in with straps as far as I can. The skin is pretty close on the ribs, but not touching. If I rivet it the way it is it will pull a dent on the front of the skin. Has anyone addressed this. I am thinking of adding an additional strip between the rib and the skin to shim it out. I can't see any reason not to. It will have rivets through it. I'm going to use A5's. I would appreciate any suggestions from anyone interested or that has a better solution.

Dave, I used the 2 x 4 along the trailing (spar) edge and a 1 x 4 closer to the nose. The skin pulled up tight to the ribs. If you've tried that, you might try using two 2 x 4s and pushing back on them as you tighten the straps.

Always use twice as many rachet straps then Zenith directions say to use, the leading edge skin should contact most if not all of the nose ribs when cinched up tight. Remember the leading edge is hidden by the slats so any imperfection will not stick out like a sore thumb unlike most any other planes..

Dave, I'm also one of those lonely 801 builders, and just wrapped my r/w leading edge last week. To bring the skin up snug to the nose ribs, I did two things: 1. I cleco'd in place the slat pickups. This gave me "handles" to keep the nose ribs aligned as I was wrapping the skin. 2. After initially positioning the skin, (and noticing the same gap you have), I placed a 12ft 2x4 edgewise along the slat pickups, then repositioned the straps around it. Doing this concentrated the pulling force of the straps directly onto the area it was most needed. The 2x4 will cover the bottom-most hole, but if you drill & cleco the other's, they will hold the skin in position while you reposition the straps again.
I've got pictures of the process, but since I just did this I haven't uploaded them to the site yet. Let me know if you want to see them & I'll post them tonight.
Good luck

Hi Kenny,
I'd like to see the pictures of how you did the leading edge wrap. From your post and the others that I've seen, it sounds like I am doing it the same way. I didn't pull the skin in quite as tight as I should have. I also adjusted how the wing sits on the table so I can pull more to the back instead of straight down or to the front. That alone seems to help. Also, using more boards on the leading edge seems to help. I think I am going to shim the areas by the slat brackets a little bit and move on.
Thanks to everyone for the helpful comments and suggestions. This isn't my first project and I have to quit getting so fixated on things when they don't go completely as planned.
