Lower wing skin panels marked out for position of wing spars and ribs. Notice the use of tins of soup and beans.

Nice progress, Tony.

I'm considering nav lights too, but as Chris B wrote, you can hardly see them in bright daylight. Maybe I'll stick with some flashing beacons instead.

Anyhow, somebody seems to like 'mushroom' soup at your place... wink

Cheers

Chris

More work carried out over the weekend. Installed the lower wing spars on both wings as indicated on the drawing as 1/8 x 1/4 spruce or hard balsa and this item was also listed on the original additional wood pack list. Only to find when dry fitting the wing ribs that the spars are far to small. Should be 3/16 x 1/4, as listed in the updated wood pack list. My work around is by adding balsa strips onto the top of the 2 lower spars before installing the ribs.

Today, I added 1/16 x 1/4 balsa strips to the top of the lower wing spars and intend to do the same with the top spars. Only a minor hitch which was easily rectified. Looking forward to the next stage of the wing build.

The wing build continues with the installation of the modified wing ribs that allow straws/tubes to slide through the enlarged hole in the rib, thus allowing me to thread the wiring through for the wing nav lights and servo leads.

19.jpg Also, the top wing spars have been fitted. I have also obtained some lead weights so I do not have to use soup cans anymore. The next part of the build will be the fitment of vertical shear webs and the false T/E & L/E strips. Will also have to think about servo selection and how to mount them in the wings. May also think about adding hard points in the wing for the possible addition of external wing tanks in the future.

Further progress has been made in the form of the fitment of the clear straws to allow the wires for the navigation lights to be run along the wing. Also the top spars have now been fitted.

I have now obtained some push rods that will be the main component of the under wing tank release system. I will also be using a single servo to operate the mechanism.

Many thanks to Martin for e-mailing me the under wing tank drawing. I have cut out all ply parts by hand using a coping saw and a file. With hindsight maybe having a lazer cutter available would have been ideal. I have now only dry fitted the 6 tank formers to the keel section and some more adjustments are required to get the alignment correct before applying the glue.

Some progress....I can report today that the T/E flap and aileron hinge support blocks have now been fitted.

30b.jpg

Also the lower wing skin holes for the servo access have been cut out.

32.jpg

I have made plywood servo support plates that will allow the fitment of the wing servos and associated access plates. Yes, I do appreciate that this may be slightly over engineered. I have also made the component parts for the external wing tank release system and associated hard points where the pylon will insert into the lower wing skin.

33a.jpg

The servo for the tank release system has its support structure made, now awaiting securing.

35.jpg

I have now installed the wiring for the wing navigation lights and the servo extension leads through the straws.

I've seen the headings for this topic but not been following too closely, but in Tesco today on the magazine rack ther is a magazine dedicated to the F-86. May beuseful for detailing, didn't actually open the mag so no details.

John, thanks for the information regarding the magazine. I had a look for it but was unable to find a copy. Many thanks for the thought.

Finally, I had the chance to connect up all the rods and wires for the external tank release system. Now I need to glue the entire system into the wing assembly. The system works very well.

Had a little challenge to adjust the wire operating arms so as to maintain sufficient clearance from the wing ribs but all sorted now.
