sandbagger Posted May 27, 2019 Author Share Posted May 27, 2019 Hi all, The basic undercarriage assembly is done now. I still have the undercarriage struts to make and attach before I can fit the assembly to the fuselage frames, Mike 109, blackbetty, LSP_Ray and 3 others 6 Link to comment Share on other sites More sharing options...
sandbagger Posted May 28, 2019 Author Share Posted May 28, 2019 Hi all, The lower wing is now installed, with some slight adjustments to clear the fuselage side frames and to give adequate access to the single wing strut mounting location. Next is the undercarriage, once I've completed making the undercarriage struts from brass tube and rod, Mike blackbetty, LSP_Ray, LSP_Kevin and 1 other 4 Link to comment Share on other sites More sharing options...
sandbagger Posted May 28, 2019 Author Share Posted May 28, 2019 Hi all, Front undercarriage struts made using 1.4 mm brass tube and 0.5 mm brass rod, soft soldered for strength, Mike scvrobeson, LSP_Kevin, LSP_Ray and 1 other 4 Link to comment Share on other sites More sharing options...
sandbagger Posted May 29, 2019 Author Share Posted May 29, 2019 Hi all, Just a lick of paint on the struts and cross bracing to attach and the undercarriage is done, Mike bstachel, TorbenD, LSP_Ray and 3 others 6 Link to comment Share on other sites More sharing options...

sandbagger Posted May 29, 2019 Author Share Posted May 29, 2019 Hi all, I'm calling the undercarriage assembly done. The wheels are not permanently fitted yet - they'll be the last thing to be fitted. So now onto the upper wing and struts etc, Mike TorbenD, MikeMaben, 109 and 6 others 9 Link to comment Share on other sites More sharing options...

sandbagger Posted June 1, 2019 Author Share Posted June 1, 2019 Hi all, The upper wing has been assembled and the plywood 'saw tooth' fairing added, Mike bstachel, Fvdm, LSP_Kevin and 1 other 4 Link to comment Share on other sites More sharing options...
sandbagger Posted June 2, 2019 Author Share Posted June 2, 2019 Ok - I need help if there is anyone out there who can explain how the interaction of the aileron control cables works, as I can't find any details of this. This I know: 1. At the forward end of the control column torque tube is a staggered double bell-crank. Twin aileron control cables are attached to each end of the bell-crank and are routed diagonally across each other to exit through the top of the opposite fuselage side. 2. The twin cables enter the underside of the upper wing, close to the inboard wing strut mounting. 3. The cables are routed around twin pulleys fitted to the rear face of the wing front spar. 4. The cables are the routed outboard to another pair of pulleys, fitted on the spar opposite the aileron control horns. My problem is that photographs show what I assume are the left inboard pulleys with the two fuselage cables routed around them. One cable is routed outboard I assume to the aileron pulleys. The other is routed in the opposite direction across the wing centre section to presumably the opposite aileron. However there appears to be a third cable routed horizontally across the top of the twin pulleys and running through a tubular cable housing. This would seem to suggest that the third cable is interconnected between the two ailerons in some way? So basically, how were the aileron cables routed across the upper wing and to and from the cockpit bell-crank??? I'm close to completing the skeletal Fokker D.VII and would want to fudge these cables using guesswork, Mike MikeMaben 1 Link to comment Share on other sites More sharing options...
sandbagger Posted June 3, 2019 Author Share Posted June 3, 2019 Hi all, I was shown a diagram of the Fokker DR.1, which had similar controls. The only photos I had were of the left wing pulleys so I assumed the right side pulleys were the same - wrong. The control cables for the aileron top control horns cross in the wing centre section - I assumed they didn't which is why I couldn't figure out their interaction. It all makes sense now. I can move on to finish the build now, Mike bstachel 1 Link to comment Share on other sites More sharing options...
sandbagger Posted June 4, 2019 Author Share Posted June 4, 2019 Hi all, The upper wing is nearly there. I just have the ailerons and their control cables and associated pulleys to add, plus the trailing edge wire. After that it'll be fitting the wing and struts, engine exhaust and propeller, wheels and aileron control cables connected - then that'll be it, Mike TorbenD, LSP_Kevin and MikeMaben 3 Link to comment Share on other sites More sharing options...
sandbagger Posted June 5, 2019 Author Share Posted June 5, 2019 Hi all, The aileron outer control cable pulleys are fitted. Made from photo-etch set intended for the Sopwith Triplane and modified to suit the Fokker D.VII pulleys. The control lines are loosely routed for now. Next are the inboard pulleys, Mike LSP_Kevin 1 Link to comment Share on other sites More sharing options...
