Left flap ready for inspection, progress on fuel tank

Today we made a lot of progress.  It was great to see some visible progress again.  We first continued work on riveting the top flap skin to the ribs.  After a slight modification to one of our bucking bars (we needed to grind off some of the steel to make it a little narrower) this task was completed quickly.  After that we riveted the bottom left flap skin to the main spar.  It wasn't an easy task but we got it done (the flap is very narrow and our hands are not).  That's all that can be done on the flap until the inspection is completed.
After that we did a quick clean-up of the workshop and then returned to our old nemesis, the fuel tanks.  We completed riveting the interior ribs on one of the tanks and riveted one of the outside ribs.  One of the fuel tanks is getting close to being ready for inspection.
There will be a break in construction for the next few weeks.  Expect an update on February 20th.

Still working on riveting the top skin onto the flap.

This is far as we can take the flap for now.


Back to working on the fuel tank for a little while.

Left Flap Assembly

This week we worked on the assembly of the left flap.  On Tuesday night we spent some time assembling the leading edge rib assemblies (these are the pieces that hold on the leading edge skin and also attach the flap to the wing.  We then worked (both on Tuesday night and Saturday) on assembling the leading edge assemblies to the main spar.  We also attached the main ribs.  The leading edge was attached to the rib assemblies with a combination of blind rivets (also called pop rivets) and solid rivets.  Finally we began riveting the top skin to the main spar.

We've been working...

...really... I swear.
After a little boo boo on the aileron before Christmas we started working on the left flap.  There are a lot of little parts and assemblies plus the skins are extremely tight (which is a good thing since the skin forms part of the structure) so it took some work.  After assembly, match drilling and the standard prep work (diassemble, debur and clean up the edges) we moved onto the prep for priming (sand the surface, clean the parts with a smelly chemical and then prime).  All parts are now primed and ready for assembly.
I've been lax in updating the site since November, I promise we'll keep the site more up to date as we progress through the rest of the ailerons and flaps and finish up the tanks.
