First up, the flanging conundrum. I bent up a sample "stiffener" with .5" flange and compared it with the noes rib jig and while it'll be tight it should fit just fine so no issue. For the 0.032 center rib aft hole spacing it occured to me there was the additional issue of where the tank false spar and inboard flap torque tube support would land. The materials I purchased earlier this year included all the steel parts needed for the wings so I pulled out the support and measured off 1/4" from the aft end of my center rib master template and marked a line. The 1/4" represents the amount of material that will be trimmed to account for the rear spar cap strips and attach plates. I then measured forward 5 7/8" the length of the support and marked a line to represent where .040 support web would need to be located. With this position known I was able to determine that for the 0.032 center ribs I can skip the flanging on the aft most lightning hole and have plenty of room for this all to come together. I'll reconfirm but I think Bob has said that the .032 ribs don't require flanging so this will workout well.

With the above sorted out I got to work on the following

1. finished routing the center ribs and noes ribs for flanging.
2. Made an additional aileron working jig to replace the one I duplicated instead of mirrored for the flanging.
3. Sense I'd done the work to locate the position of the false tank spar I made jigs for the short ribs aft of the false spar
4. Then back to the deburring races, got all the flap blanks deburred.

Good progress!
