I am working on the cowling and have the top lined up  precisely. The bottom cowl alignment has me stumped however. The aft lower  section is flush on the 1001Q as well as the skins along the fusellage on the  bottom and sides. Everything looked great until I took the spacers off for the  side hinge (47 pg 6 step 11) now the bottom cowling forward section (behind the  spinner) is very close (aka the 1/8 space is now more like 1/32) Thinking I did  something wrong I went back and realigned the bottom, again everything lines up  but the bottom area is the same.

 Any ideas?

 Thanks!

 Pascal

Sounds like you have to go back and extract more material from the firewall area - very slowly and carefully - perhaps on both the top and bottom halves. It is an exasperating job and must be done slowly and very carefully to keep the fit at the spinner correct.



Note of caution:  My cowling wound up a bit offset to the right - maybe only 1/4 inch offset as you look at it from the pilot seat. This seems like an almost absurdly small error, but when I went flying (after the engine settled on its mounts) the #2 cylinder valve cover (front left) hit the cowling during power changes and at start -up. Solution - I had to put a dent in the valve cover (again very carefully)n to prevent the terrible vibrations.

To help those after me as you may very well have the same issue:

Spoke with Vans looks like my cowling is fine as is the issue with the 

bottom gap is normal and not worth pursuing. In my case I'll be sanding it 

back to make the gap larger for easier removal and install of the lower 

cowling.
