I am trying to bolt the slats to my wing. There are two jigs used,
one for the bottom alignment and one for the top gap. But when I
have the bottom set correctly there is too much gap at the top. The
bracket on the wing hits the slat and I can't get them close enough
together to meet all the specs. There is supposed to be a 16 to 18mm
gap between the top of the slat and the top of the wing. But the
closest I can get at the top is about 21mm. All 8 brackets are about
the same. I have already filed down the tops of the brackets so that
there is a 10mm radius around the top hole.
Anyone hit this problem? Any suggestions before I send ZAC a note
and ask if I can reposition the mounting holes and cut down the
bracket (or just have a 20mm gap at the top)?

Doug,
If you lift up slightly at the bottom(or better, slide slat up from bottom a little), the gap will close at the top slightly and bring it in spec.. The wing nose skin slightly bulges out on the bottom where it bends around the nose ribs. This slightly moves the jig on the bottom lower than shown on the plans. Look at how the brackets on the slats and the wing come together at all 4 points. There is a natural fit to these. If the slat brackets look like they are sitting alot lower than the wing brackets this is due to you trying to align the slat grounded to the jig. This will work on their drawing but in reality I found it will not work. The drawing is basically showing that if you set the wing on a table with the slat attached, the slat edge will touch the table. In reality the slat edge will sit slightly higher than the bottom surface of the wing. I got 18 mm between the top of wing and slat. Do not cut your brackets or reposition holes. I did round off the top as you did a
lso. You used separately made jigs to carefully position these brackets on the slat ribs and the wing nose ribs. They should line up pretty close
in the final assembly.

Also, isn't the distance for the top edge 14-18 mm, not 16-18?
I was really concerned about that 16 mm. distance. So much so that I drove
out of my way on a trip to Ft. Leavenworth, KS to stop by the factory and
check out the demo. I slipped my finger through the edge and started
sliding it from the tip toward the root of the wing. The edge distance on
the demo fluctuated quite a bit. I thought that it should be a smooth 16 mm
gap with no deviation.
So, for what it's worth, the slat edge distance is not consistent from one
end to the other.

I had a bracket clearance problem also, I filed them down until I got the
right Gap clearance and then drilled another hole for a third bolt thru both
brackets where the edge clearance was getting too close to the edge
