I am trying to lay out a fixture to build the upper Ailerons and I
can't make the numbers work. I drew it up using and trying to verify
what I think are the critical dimensions, ie the 57.750 over all length
and the locations of the hinge pockets, 8.500 and 11.000.
When I do this I get a *aligned* center to center distance of the pockets
at 33.100 vs the 33.000 that shows on the print. The 8.625 dimension
in the bottom view looks to be wrong also, I am thinking that that
dimension should be to the end of the spar and not to the end of the rib.
Here are a couple of pictures of my lower aileron jig and kind of a poor
pdf attempt of the upper aileron fixture drawing.
If anyone wants to cross check this I can output dwg or dxf files. I can
upload these or email them.
Thanks,
John Burnett

ps: On my lower view in the pdf I am dimensioning the spar only.
