Sandbagger Posted April 3, 2019 Share Posted April 3, 2019 (edited) Hi all, The first of the Fokker D.VII pair is completed. So now I'm starting the second of the models, the 'skeletal' model. This will be a full view model with 3D printed parts from 'Shapeways'. The donor engine is from the 'Wingnut Wings' Fokker D.VII (OAW) built with the following replacement 3D printed components: Created by Bob Monroe ('Flugzeugwerke') and available from ‘Shapeways’. Mercedes D.III Oil Pump, Mercedes D.IIIa Cylinders (hollow), Mercedes D.IIIa Crankcase, German Aircraft Magneto, Mercedes Cylinder clamps, Gun synchro mechanism, The aircraft structure will be the 3D printed Fokker D.VII structure. Created by Richard Andrews ('Aviattic') and available from ‘Shapeways’.Shapeways There will be other after market parts used. I thought I'd start with the engine, which had to modify slightly as the internal mountings in the 3D sump and block are too small to accept the kit supplied propeller shaft. Instead I've made one from brass micro-tube to fit not only the 3D engine but also the 'Proper Plane' Heine propeller.

clive_t Posted April 3, 2019 Share Posted April 3, 2019 OK I'm early for this one, looking forward to it! Link to comment Share on other sites More sharing options...
Smithy Posted April 3, 2019 Share Posted April 3, 2019 If it's anything like the first one it promises to be an absolute humdinger! I'll be watching this in awe no doubt 1 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 4, 2019 Author Share Posted April 4, 2019 Hi all, A few more engine bits prepared. Spark plugs made from micro-tube and 'RB Motion' aluminium nuts. 'Taurus' manifold locking rings - cut and sanded to fit the 3D printed engine, Mike 2 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 5, 2019 Author Share Posted April 5, 2019 (edited) Hi all, A couple of magnetos each made of four separate 3D printed parts. The ignition leads support tube made from micro-tube. The magneto drive modified to fit the 3D engine with a brass rod for the magneto drives. Also the cylinders are mounted onto the engine block, Mike Edited April 6, 2019 by Sandbagger 4 Link to comment Share on other sites More sharing options...
f matthews Posted April 5, 2019 Share Posted April 5, 2019 Spectacular. This thread (and the other) are great reading! Link to comment Share on other sites More sharing options...
Sandbagger Posted April 6, 2019 Author Share Posted April 6, 2019 Hi all, Starting to assemble the engine accessories now. So far the spark plugs, ignition lead support tubes, camshaft, air pump, coolant drain tap and cylinder base bridging clamps. Still plenty more to do, Mike 3 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 7, 2019 Author Share Posted April 7, 2019 Hi all, The engine has progressed a bit more now with the addition: The conical valve springs Crankcase breather pipe Magneto drive assembly with two 3D printed magnetos Two air pump to crankcase pipes Decompression valve. Still have to add ignition leads, intake manifold with locking rings, water pump, coolant pipes, oil filler pipes, sump oil sight glass. There's also a couple of other pipes plus engine controls.

Brandy Posted April 7, 2019 Share Posted April 7, 2019 Very impressive! Rather than crediting Shapeways though, I think you should give proper credit to who ever designed the parts....yourself? I've done some myself and it's by no means an easy task (well not for me anyway!) Ian Link to comment Share on other sites More sharing options...
Sandbagger Posted April 8, 2019 Author Share Posted April 8, 2019 (edited) I'm not that clever to print parts. I've amended the first post to credit the creators of the parts I'm using, Mike Edited April 8, 2019 by Sandbagger Link to comment Share on other sites More sharing options...
Sandbagger Posted April 8, 2019 Author Share Posted April 8, 2019 Hi all, The 3D printed parts are detailed but as can be seen from the shot below, some are very small. This is a pair of machine gun synchronization mechanisms, each made up of four separate parts. The biggest problem is separating them from the base block without damaging them!!

Sandbagger Posted April 10, 2019 Author Share Posted April 10, 2019 Hi all, The end is in sight for this engine build. I've added the decals, ignition leads, gun synchronization mechanism, oil sight glass, generator and drive, cylinder fuel primers, water pump, intake manifold with locking rings, crankcase breather pipe and additional pipes. All that's left is to add the engine mounted throttle and spark advance (ignition timing) controls - the remainder of the control runs can't be added until the engine is fitted into the fuselage (with the cockpit), Mike 3 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 12, 2019 Author Share Posted April 12, 2019 (edited) Hi all, I've added the control linkage to the top of the twin carburettors, which consist two levers, connecting rod and cable pulley. Also the connected levers on the top of the attached 'speed controllers;. I also created the frame mounted throttle bell-crank and the two cross bars on the forward fuselage frames, which are missing from the kit parts, Mike Edited April 13, 2019 by Sandbagger 1 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 13, 2019 Author Share Posted April 13, 2019 Hi all, The final on-engine control linkage has been added, which is the spark advance (ignition timing) for bottom magnetos. For now the engine will be put to one side so I can make a start on the cockpit, Mike 1 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 13, 2019 Author Share Posted April 13, 2019 Hi all, The kit supplied fuselage side frames married to the 3D printed fuselage. This required cutting both, as both have a pilots seat frame and only one can be used of course. As the join between the two could be a weak area, I chose to fit them together using brass micro-tube. This gives more rigidity to the join of the fuselage and allows the fitting of the pilots seat frame from the kit (part A26), Mike 3 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 16, 2019 Author Share Posted April 16, 2019 (edited) Hi all, Cockpit floor with controls and seat done, Mike Edited April 16, 2019 by Sandbagger 2 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 18, 2019 Author Share Posted April 18, 2019 (edited) Hi all, I've started on the cockpit pipework. The pipe connections under the fuel tank. Behind the instrument panel is the fuel valve manifold (made of micro-tube) connected to the pilot's four selectors. Two pipes out are for connecting the supply from the main and auxiliary fuel tanks. From the bottom of the manifold will be the two supply pipes to the engines duel carburetor. Electrical cables added to the rear faces of the starter magneto and ignition switch. Mike Edited April 18, 2019 by Sandbagger 3 Link to comment Share on other sites More sharing options...

Sandbagger Posted April 19, 2019 Author Share Posted April 19, 2019 Hi all, The pilot's hand operated fuel pressure pump pipe is done. Also the rear gun support frame and the instrument panel are fitted, Mike 2 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 20, 2019 Author Share Posted April 20, 2019 Hi all, A few more things added: Fuel lines from the underside of the fuel tank to the fuel gallery behind the instrument panel. Grease line from the pilot's 'screw down' pump to the engine mounted water pump. Fuel drain line from the underside of the fuel tank to outside of the fuselage bottom. Oil line from the oil tank (in the fuel tank) to the engine driven oil pump. Now it's onto the wiring up the magnetos and adding the throttle and spark advance (ignition timing) controls, Mike 3 Link to comment Share on other sites More sharing options...
Sandbagger Posted April 21, 2019 Author Share Posted April 21, 2019 (edited) Hi all, Tachometer drive added from gun synchronization mechanism. The two carburetor fuel feed pipes from the gallery behind the instrument panel, The two machine gun trigger cables from the control column to the gun synchronization mechanism, Mike Edited April 21, 2019 by Sandbagger 2 Link to comment Share on other sites More sharing options...
