So many holes, so much deburring

Full and productive day in the shop yesterday, but not a lot of pictures to share.

Started taking the nose and lower skins off the wing in preparation for deburring and priming.  If I'd only known how many holes there would be to deburr, I wouldn't have drilled so many!  Just kidding, but man there are a lot of holes to clean.

Lower outboard wing skin, deburred and primed.  This section is small enough to store flat, so I deburred, primed and riveted the skin stiffener in place.

Inboard nose skin deburred and primed.  I found it convenient to leave it on it's edge on the floor and roll along on the stool with the deburring tool.  Primed the areas using a sheet of newsprint held behind.  The lower edge shown will be primed later (didn't want to get primer on the carpet runner):

Lower wing skin removed and flipped over for deburring.  Very pleased to see all rib holes are centered on the rib flanges and I don't have any elongated holes - bonus!  Once complete and primed, I rolled it up for storage until ready for re-assembly.

At this point I can begin the final riveting of the wing skeleton.  Removed nose ribs from the spar, deburred them and the holes in the spar and final riveted them to A5:

Next I finished the final rivets on the wing tie down ring (not pictured) and the rear channel, including the channel to ribs and the rear strut pickup.  This joint has seventeen A5 rivets and an AN3 bolt on the face of the rear channel alone - plus another eight A5 rivets once the skin is in place.  It's one heck of a stout assembly once it's in place:

Final riveting of the flapperon arms might wait until I have the lower skins on, or I might rivet them first.  It's probably better to do them now while I have unfettered (today's big word) access, so I'll do that before I rivet the skins on.

I'm getting closer to fitting up the wing tip.  I'll need to cut it out from the blow mold process that it is made from.  These are the ones I picked up in 2019 when Dad and I went to Montreal-St Hubert
I'll probably cut them out rough with a Dremel cutting wheel and leave enough of an edge that can be trimmed, sander later.  It will be easier to fit up with the wing upside down on the bench:

Still a bunch to do, but the wing is essentially ready for the skins to be added back and final riveted to the skeleton.  I need to add the support Ls at the spar and rear channel tips that support the wingtip.  Before I rivet the skins though, I also need to vacuum out all the drill and deburr debris so when I flip the wing over it doesn't get into any areas I won't be able to reach.

I'm also close to fuel line routing decision.  I can't add the trailing edges in permanently until that gets finalized and installed, which can't happen until the tanks are fabricated and the rear channel root doubler is dilled and deburred for the fuel line passthrough.  Need to start looking for grommets for that to0.

Blog posts in the coming episodes will likely be shorter but more frequent.  Thanks for following along!  More to come.....
