This was another long, long day but I feel like I made good progress. Got the extension piece made for the attachment of the fiberglass trim on the wing tip. Also drilled out several spar connections that were in 3/32 holes to 1/8" holes, ready for deburring and rivetting. Tomorrow's work will be a few more of those up-drilling operations on the rear spar, followed by disassembling everything for deburrring, re-assembly and final riveting. Looking forward to it.
