This question to Bob...

[Archer39J]

I'm calling it, dwg #4 represents the exterior profile of a completed wing, skin and all. I don't really know, but I'll bet 10 internet dollars on it

ETA: Actually, false. If you look at dwg 3 you find this:

No internet money for me today...

Did you intend us to route the rib form blocks directly off the master rib model--
so that the wing's completed thickness would be an extra .100 in (4x.025) thicker
than the mylar drawing ? ( I was intending on doing it with a copy bit this way)

OR-

Do we need to reduce the form blocks thickness by .050 on all 4 sides so the completed wing's thickness matches the mylar sheet #4 ? (form block + rib and
skin added on top and bottom = mylar dimensions)

Also--- when I am sanding down my master rib model-- should I sand to the
outside of the line in the mylar, to the center or to the inside of the line?

I dont want a dimensional error on the ribs to intrude into the surrounding
parts so that I later run out of slack later.

I asked the question about form block size on the bearhawk forum but no
one else knew the answer either--- so I will pass on your insights to them
so we wont have to ask again ! Sorry to bother you but I dont want to cause
an error right at the beginning ! Thank you ahead of time !
