How do you spot the old rib holes in the spar? Strap duplicator or eyeball it ? 1 pound for paint on the spars seems worth it to me.
The front of the front spar.... There are very few "extra" holes on it... First four from the but rib are for the tank bay ribs... Then it is full rib, nose rib, full rib, nose rib and so on until you get to the full length aileron rib at the end.... Also, there is one special rib that goes at the wing strut attach point... If you look at the above pictures it is the one with a close up shot of the screws... The upright is notched for clearance of the strut attach blocks that are bolted onto the spar face...
Once I get the front spar ribs located it is just a matter of measuring from the butt rib each location across the front spar and replicating along the rear..

I don't think I worded my question well. Do the new ribs come with screw holes to go back in the existing holes on the spar? I have only disassembled these type of wings. Never put one back together.

Yes, they are pre-drilled at about a 1/16 hole... I finish drill them at a #40 for the screw...
I got my small parts primed and painted this week for my left wing. Hope to prime and paint the spars next week. Made the trailing edge behind the fuel tank today for the right wing. The next warm week around here I will form the leading edge pieces using a pvc pipe and a shop vac. This method has worked great doing Luscombe and Great Lakes leading edges. There is several you tube videos on vacuum forming leading edges.
The 90 degree drill pictured in post #131 is without a doubt one of those "don't use it often, but when you need it..you need it" tools. Not cheap, and I waited a long to finally get one. But, has been totally worth it while drilling the small rivets on the rib assy's.

I've rebuilt mine twice now... Bearings eventually go bad... Glad they are easily available...
Did a little today... Waiting for parts to show up from Univair...
Did a scratch and spray on the compression tubes... Replacing one of the root tubes due to dents, will take pics of that when the new one gets here...
Hung and painted the tubes with what was left of the white paint I had available...
Realized my rib spacing was off, got that figured out and corrected..
