sandbagger Posted May 13, 2019 Author Share Posted May 13, 2019 Hi all, I've added the padding rim around the fuselage decking panel and onto the top of the cockpit side frames. This was done using 2.0 mm diameter plastic tube which was sanded to form a grip for painting. Then it was slit along one side and located over the decking and secured in position with thin CA adhesive. Finally it was primed, painted 'Humbrol' leather (62) and 'Tamiya' Hull Red (XF9), sealed then given a clay wash and finally sealed with 'Alclad' Light Sheen (ALC-311).

sandbagger Posted May 13, 2019 Author Share Posted May 13, 2019 Hi all, Tail unit assembled from the 3D printed parts. Very fragile once separated from the support frame, so should prove interesting. The elevator was missing the inboard trailing edge profile, presumably missed during printing process. Therefore I had to make the profiles using 0.8 mm brass tube.

sandbagger Posted May 16, 2019 Author Share Posted May 16, 2019 Hi all, Well the fuselage is completed, apart from fitting the engine exhaust and the propeller. The Rudder and Elevator control runs have been connected with the turnbuckles under the pilot's seat. Also the tail plane to fin bracing cable. The entire fuselage has been weathered and sealed. So now it's on to the lower wing, followed by scratch building the skeletal undercarriage assembly, which unfortunately is not available as a 3D printed part.

sandbagger Posted May 17, 2019 Author Share Posted May 17, 2019 Hi all, The 3D printed lower wing is detailed enough, but as normal there are details that can be added to make it more authentic. Early production Fokker D.VII aircraft were fitted with bracing tapes that were routed across the wings between the front and rear wing spars and between the rear wing spar and the wing trailing edge. These tapes were routed in a diagonal ‘zig-zag’ form, up and over each wing rib. However later production aircraft were fitted with 10 mm square strip wood as replacements for the earlier tapes. The 3D printed wings represent the later, strip wood version. Although these strip wood struts can be left to make the model build easier, I've chosen to remove the wings strip wood struts and represent the earlier bracing tapes. In addition, the two wing halves, when test joined at the centre section spars, showed a higher than expected dihedral angle. Therefore I had to shave away material from the spars to achieve the correct angle. Finally the leading edges of both wings were fitted with 'saw tooth' plywood fairings, which will need to be scratch made, as will the trailing edge support wire for attaching the linen covering. So far: Spars adjusted. Strip wood bracing removed. Diagonal bracing struts added to inner and outer trailing edges. Holes drilled at the wing strut attachment points for attaching the wings internal cross bracing cables. Wings scrapped clean of wax support material, assembled and primed. The upper wing, which is in three sections, will require similar treatment. Mike 5 Link to comment Share on other sites More sharing options...

sandbagger Posted May 18, 2019 Author Share Posted May 18, 2019 Hi all, The leading edge plywood 'saw tooth' fairing is tricky to do, but can be done. Structure drawing of 1/72 scale resized by 160%, then printed, cut out and used as a template on 0.2 mm thick plastic card. The fairing is test fitted and adjusted where necessary then secured in position using thin CA adhesive. Starting on the top of the front wing spar then once set, rolling the wing over the fairing and applying adhesive at the same time., Mike 5 Link to comment Share on other sites More sharing options...
sandbagger Posted May 20, 2019 Author Share Posted May 20, 2019 Hi all, The lower wing is nearing completion. It's been painted with 'Tamiya' base coat then oils for wood effect. Internal wing bracing with turnbuckles added. Leading edge 'transportation 'bump stops' added. Internal double bracing 'zig-zag' tapes installed (instead of the original 'strip wood' struts, which were removed). I still have the trailing edge wire to install (for attaching the wings linen covering). Also the final weathering will need to be added Mike 4 Link to comment Share on other sites More sharing options...

sandbagger Posted May 21, 2019 Author Share Posted May 21, 2019 Hi all, The lower wing is finished now, with the trailing edge wire fitted and overall 'dumbing down' carried out using 'Alclad' Light Sheen lacquer mixed with 'Tamiya' Smoke (X19). So now it's on to scratch making the undercarriage fairing and axle assembly (not available as a 3D printed part), Mike 8 Link to comment Share on other sites More sharing options...
SapperSix Posted May 23, 2019 Share Posted May 23, 2019 Excuse me but my jaw was on the floor so it took me a minute to respond. Following with great interest. Fantastic stuff here!!! 2 Link to comment Share on other sites More sharing options...
sandbagger Posted May 24, 2019 Author Share Posted May 24, 2019 Hi all, The undercarriage fairing assembly is basically built. Made from 0.8 mm and 1.0 mm thick plastic card, 1.2mm, 0.8 mm and 0.5 mm brass rod and tube. The wheels are hand made by 'Steve Robson' out in Australia. It's still to be finalized and painted etc. I'll also need to make the struts as the kit supplied items fit into the kit fairing and therefore are not long enough to attach to the angled support blocks on each side of the exposed axle box ends, Mike 5 Link to comment Share on other sites More sharing options...

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 5 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 2 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 1 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 2 Link to comment Share on other sites More sharing options...
