Thanks, this is really helping. I cut out 6 spars from a 5# sheet,
then trapped them between two sheets of 1/16 to sand the tapers. I had
marked the three stiffest spars before tapering and they came out to --
-----.059gm too cool.

Now my next problem (man you guys are going to get sick of me)

I have two of John Ks plans (Eidolon and the CatII) The Eidolon has
compression ribs and regular ribs listed. The CatII gives top,bottom
and uprights for the compresson ribs. Does the Eidolon not have built
up compression ribs?

Oh, and I'm going to soak and bake my ribs due to their long length
and I don't have the right C grain at this time.

Thanks again.
