Keep it simple.  No tools need to be made to build a Flybaby.  I've built
one and I know.  Let's talk about ribs.  I cut out each set of wing ribs at
one time on a band saw.  I stuck all the blanks together using double back
tape and then taped a full size template on top of the stack.  When you
finish just pull them apart and they are all exactly the same size.  Nose
ribs I did four at a time.  When I assembled the ribs I first attached both
the upper and lower capstrips to the nose ribs with brass nails and glue and
then worked aft to the trailing edge.  I only used nails in the nose ribs.
I used spar section blocks to simulate the spar as I assembled the ribs.  My
method of clamping the ribs while they dried was to use heavy rubber bands
wrapped around the ribs every inch.  If you have cut the ribs properly and
use the simulated spar sections as you set the rubber bands, the ribs will
be perfect.  Trust me it works.  My fixture for wing assembly was nothing
more than a solid flat door on saw horses.  Make sure that your table is
square so that you can us its edges as reference points.

Frank, Steve here.
I'm going to build a clamping device for the ribs.
I will buld the ribs flat against the table.The bottom will rest against
a 3/4"sq. straight piece of wood drywall screwed to the table. This will
allow a stop for the bottom capstrip.
Then the top will be cut to the shape of the rib out of 3/4" ply. the
lingth of the rib about 6" wide. glue some 3/4" insulating foam rubber
to the inside edges of this air foil shaped piece. and the bottom stop
strip .Ths will alow equal pressure all around the rib. May need to wax
the foam, or cover with masking tape as not to stick to the top
capstrip.
2 or 3 blocks screwed to the table and wedges to tighten the gap when
clamping.
This is just an idea I thought of when I built up the first rib .
