sandbagger Posted February 22, 2019 Author Share Posted February 22, 2019 (edited) Hi all, Now that the fuselage is buttoned up I've moved onto the engine. As usual not an OOB build. Modifications will be (I hope). Complete timing gear Fuel priming cups Spark plugs (late type) Intake manifold nuts Ignition leads Engine control Coolant pipes Engine sump apertures Oil sight glass. First off is the removal of the coolant pipe for the cylinder jackets, which is pre-molded in between each cylinder. Also the conical vale springs.

sandbagger Posted February 22, 2019 Author Share Posted February 22, 2019 Hi all, The cooling of the engine cylinders was carried out by cooled water from the radiator being fed by pipes to the water pump, located on the bottom, rear of the sump. This water was pumped through an outlet pipe and through interconnected stub pipes at the bottom of each cylinder. The water was then pumped up through the cylinders jackets and out through the interconnected stub pipes at the top of each cylinder, then forward to the front of the engine and back to the radiator for cooling. The kit supplied cylinder block has the pre-molded coolant pipe for the cylinder jackets, but it looks unrealistic, as it extends through and between the separate cylinders, presumably to act as a solid fixing base for the cylinder block. I've cut this pre-molded pipe away to separate the cylinders and replaced it with short lengths of 0.85 mm diameter plastic rod, with a chamfer at at end to fit the contour of the cylinders.

sandbagger Posted February 23, 2019 Author Share Posted February 23, 2019 (edited) Hi all, A magneto was located on each side at the rear of the engine. These were driven by the engine through a split drive shaft. Attached to each magneto were six ignition leads, which were routed through support tube attached to each side of the cylinder block. Each cylinder ignition lead exited the support tube through an aperture and was then attached to the cylinder spark plug (two per cylinder). The pre-molded support tubes supplied in the kit seem under sized, so I replaced them with micro-tube. The sump of the engine was essentially a ‘wet’ sump, as the oil reservoir was in the rear and lowest part of the sump. The oil was drawn from this reservoir by the oil pump (located at the rear of the engine) and distributed through the engine, after which it returned to the reservoir to be recirculated. The forward part of the engine sump appears to have been open, as can be seen through the open apertures and the front of the sump in the following photograph. An oil contents sight glass was located on the sides of the oil reservoir at the rear of the sump. Some engine installations had an oil tank installed in the engine bay and outside the engine, although this particular kit does not have this feature. I've drilled out the apertures and created a sight glass on each side - the 'glass' will be made of PVA adhesive once the engine is built. Mike Edited February 24, 2019 by sandbagger BiggTim, D.B.

monthebiff Posted February 23, 2019 Share Posted February 23, 2019 (edited) Really cool work Mike, of interest us the lozenge on the seat......is that a made up thing or is this a genuine thing that happened as I have no idea. Whatever, it looks cool. Edited February 23, 2019 by monthebiff BiggTim 1 Link to comment Share on other sites More sharing options...
sandbagger Posted February 23, 2019 Author Share Posted February 23, 2019 (edited) Hi all, To enhance the engine detail I replaced the engines pre-molded locking rings for the fuel inlet manifold with the ‘Taurus Models’ engine intake manifold nuts (3211). The kit does not have spark plugs to fit to the six cylinders (two per cylinder), however the cylinders do have a pre-molded location hole for the spark plugs. The plugs to be used are from the ‘Taurus Models’ engine spark plugs (late type) (3204) set.

sandbagger Posted February 23, 2019 Author Share Posted February 23, 2019 Regards the lozenge on the pilots seat. I'm not sure how common the practice was to have lozenge linen applied to crew seat, but as an example, here's a shot from Wingnut Wings (Albatros OAW). Richard at 'Aviattic' supplies decals for the seat in his Fokker D.VII linen effect lozenge decal for the fuselage. I initially prepared the front face of the metal seat for a wood effect, but then spotted the decal, so applied that.

sandbagger Posted February 25, 2019 Author Share Posted February 25, 2019 Hi all, I decided not to use the 'Taurus' spark plugs after all as although they are good, attaching the ignition leads to the tiny end of the plug was difficult to do without leaving it looking unrealistic. Instead I've made the spark plugs from 0.8 mm and 0.4 mm diameter 'Albion Alloys' brass tube with a 0.31" aluminium nut from 'RB Motion'. This way the fine lead wire I use to represent the ignition lead can locate inside the 0.2 mm bore of the 0.4 mm tube.

sandbagger Posted February 25, 2019 Author Share Posted February 25, 2019 Hi all, The fuel primers for each cylinder are built using the 'Taurus Models' fuel priming cups (3219). They'll be painted when fitted to the engine. Mike BiggTim, LSP_Kevin and MikeMaben 3 Link to comment Share on other sites More sharing options...
sandbagger Posted February 27, 2019 Author Share Posted February 27, 2019 (edited) Hi all, The engine is progressing although there's a way to go yet, not including application of the weathering effects: Cylinder fuel primers Fuel manifold and locking rings Coolant pipes Ignition leads Oil filler pipes Exhaust The oil sight glasses were made by dropping PVA adhesive into the holes - it dries clear (good for making windows etc). This engine is the test bed for the second Fokker D.VII and will be more or less covered by the forward fuselage panels. The next engine will be visible when I build the second aircraft, which will have the internal structure and engine etc totally exposed I know it seems senseless to cover the detail on this engine, but at least I know it's there, Mike Edited February 28, 2019 by sandbagger Fvdm, LSP_Kevin, MikeMaben and 1 other 4 Link to comment Share on other sites More sharing options...

sandbagger Posted March 1, 2019 Author Share Posted March 1, 2019 Hi all, Well the engine is done. There are details I've not added as this model will have the engine fully enclosed. The second Fokker D.VII will have more detail as its engine will be fully exposed, Mike Sepp, scvrobeson, bstachel and 4 others 7 Link to comment Share on other sites More sharing options...

sandbagger Posted March 6, 2019 Author Share Posted March 6, 2019 Hi all, A few more bits done. 'Properplane' Heine propeller treated with 'Tamiya' Clear Orange then Hull Red. Weathered with 'Tamiya' Weathering Master Set B (Rust) and 'AK Interactive' Kerosene wash. 'GasPatch' Spandau 08/15 extended handle guns with 'Alclad' Gun metal, then Steel. Weathered with 'AK Interactive' Kerosene wash and 'Tamiya' Rubber Black. Figures assembled and primed for painting - Anthony Fokker ('Aviattic'), Photographer and camera ('Black Dog').

sandbagger Posted March 9, 2019 Author Share Posted March 9, 2019 Hi all, I've applied the 'Aviattic' linen effect lozenge to the first Fokker D.VII now. Under the decals, although it's difficult to see in the shots, is pre-shading. I've yet to apply the kit decals and weather it all in, Mike Fvdm, scvrobeson, MikeMaben and 3 others 6 Link to comment Share on other sites More sharing options...
