Martin Gay Posted November 23, 2019 Share Posted November 23, 2019 Hi John, You may have missed the post on another thread but the tailplanes should be two laminations of 1/4" balsa - NOT 1/8". Martin. Quote Link to comment Share on other sites More sharing options...
John H. Rood Posted November 23, 2019 Author Share Posted November 23, 2019 Martin, I just plain screwed up! Indeed I remember you going to considerable trouble to clarify that little typo and now I’ve gone and resurrected it! Sorry about that! I owe you one there. I wish this forum allowed us to edit and delete at will. But I can at least reiterate: THE TAILPLANE IS MADE OF TWO LAMINATIONS OF 1/4" BALSA, NOT 1/8" !!! If any doubts, just look at the airfoil section on the G&M plan -- it is clearly of 1/4th balsa laminations, not 1/8th. Edited By John H.

Martin Gay Posted November 23, 2019 Share Posted November 23, 2019 No worries! Just glad we caught it now, and not after you had shaped the tailplanes! Quote Link to comment Share on other sites More sharing options...
John H. Rood Posted November 26, 2019 Author Share Posted November 26, 2019 SO THERE I WAS... minding my own business, immersing myself in aliphatic, quietly communing with The Monolith, when THE EXTRATERRESTRIALS arrived. They wanted to "probe" me, I respectfully declined, recommending that they try a normal human instead. They said they'd consider. Overhead photo courtesy the MotherShip.

John H. Rood Posted November 27, 2019 Author Share Posted November 27, 2019 Fuselage sub-assemblies completed. G&M's design/engineering is a big help as things really do square-up. Next step is to make up the aft spine pieces and then things really come together. A really fun build underway! Quote Link to comment Share on other sites More sharing options...
John H. Rood Posted November 27, 2019 Author Share Posted November 27, 2019 Drawing reference lines has helped double-check my efforts at alignment. Even just labeling things as to up/down/fore/aft/port/starboard etc helps me with basic orientation. Quote Link to comment Share on other sites More sharing options...

John H. Rood Posted November 27, 2019 Author Share Posted November 27, 2019 Why use just one fabulous clamp, when you can use FIVE THOUSAND? Or...

Chris Barlow Posted November 27, 2019 Share Posted November 27, 2019 Did the clamps beam down from the mothership and start breeding? Looks tidy John. The snug joints in the parts really do make assembly easier and more accurate. Quote Link to comment Share on other sites More sharing options...
John H. Rood Posted November 27, 2019 Author Share Posted November 27, 2019 Thanks, Chris. Working off a 3/8' tempered glass tabletop, all gluing so far with Titebond aliphatic. The clamps have been asking me about yes/no to an operating rudder, flaps, air brakes, slats, and so on... and all I could think was "I need to keep this one simple" and but at my age what I will REALLY need is an onboard OPERATING PILOT RELIEF TUBE EVACUATION system! They also leaked these secret NAA photos of the very first liftoff of the XFJ-2; this happened on 27 December 1951 at NAA Los Angeles Division's adjacent Los Angeles International Airport. The great Bob Hoover at the controls. Quote Link to comment Share on other sites More sharing options...

John H. Rood Posted February 23, 2020 Author Share Posted February 23, 2020 Thanks, guys! I've been clamping the wing jig to a very flat and sturdy 1/2" thick glass table top with good results thus far. The clamps also have helped me forcibly "tweak" the jig to align properly with the rib positions et al. I'm using hard balsa for the spars and the false LE/TE strips. Gluing with Titebond "Thick & Quick" and Titebond II. Quote Link to comment Share on other sites More sharing options...

John H. Rood Posted February 26, 2020 Author Share Posted February 26, 2020 LE, spars, and TE of hard balsa. Joints all cleaned up nicely. Quick photo-op before securing everything back down on the jig so to (hopefully) ward off any warping. Next is to box up the spars via the vertical-grain shear webbing and then install hinge blocks and servo mounts. Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted February 26, 2020 Share Posted February 26, 2020 Getting there with your wing, John. Keep up the spirit... Cheers Chris Quote Link to comment Share on other sites More sharing options...
Harry Twist Posted February 26, 2020 Share Posted February 26, 2020 Hi John, that looks very tidy, nicely done! Loving the hovering background A4 Skyhawk, they do look great in bare wood! Quote Link to comment Share on other sites More sharing options...
