2 hrs. starting to ream out the holes to attach the ribs to the spars - finally!

Rechecked the rib alignments with my jumbo straightedge.  Looked good, so starting using my 4mm rivet-sized chucking reamer on all the rib holes.

NEXT SESSION:

1. Start riveting the ribs to the spars!!
2. Fellow builder Gordon recommended that I clear away much of the sealant around the fuel drain to all free flow of water and debris out of the drain.  With so much sealant, it could block the flow.
