  1. Thanks for your advice Kev and Bevan. I decanted the spray into a clean empty Tamiya jar and added about 15% Mr.Color Leveling Thinner 400. Left it alone for about 40 mins and watched the bubbles fizz as the gas vented off. Sprayed it through the airbrush a short while later and it worked a treat. The paints are great, quick drying but sometimes you just want the precise control of the airbrush instead of the broad brush effect of the spray can.
  2. Can anyone tell me which thinner to use with the Tamiya spray cans please? i have read of modellers decanting it into a container, then leaving it to degas for an hour before attempting to spray from an airbrush. There must be some risk of the paint drying out if thinner is not added in time. Can MrLevellingthinner 400 be used or is it better to use the Tamiya own brand , yellow, white, or blue top? Thanks for any advice as this is the first time I have attempted this.
  3. Yeah Finn, now you’re talking. I grew up with those very aircraft flying overhead my school at Dhahran in the ‘70’s. Come on Airfix let’s get on with it.
  4. I think some members here might be able to answer Mike. Is there more than one manufacturer which produces custom sets of seatbelts and canopy masks for specific aircraft?
  5. The EE Lightning is the English Electric Lightning as also utilised by the Royal Air Force but which has not been seen in the sky for several years now. I too would buy a F-35 version though if it appeared in 1/24. Just to remove any doubt, the Jaguar referred to is the Sepecat Jaguar not the four legged or four wheeled version.
  6. Experience of Eduard canopy masks has been wholly positive in my experience. I purchased the ( different manufacturer’s) seatbelt and canopy inside/outside masks for convenience and also because the reputation of the manufacturer for seatbelts, led me to erroneously believe their quality products and reputation would extend to the canopy sets too. Indeed their own marketing states “High quality detail set” and “Tested on Humans” on the packaging. Well they may well have tested their products on humans, but they didn’t test them in the kits they are designed to be used with. ”Jimbo”- I have used the Eduard masks sometimes after a period of several years before getting round to using them and have noticed no shrinkage or drying out, even whilst living in a very dry environment.
  7. All the WNW re-released in 1/24 scale! They have already got all the CAD in 1/32 so why not?
  8. I have recently purchased a couple of precut vinyl mask sets for the inside and outside of the canopies for the Tamiya Spitfire IX and the Revell FW190 in 1/32. They are produced by a certain manufacturer of very good scale seat belts without naming them. The masks when applied are way off and the incorrect size leaving gaps of 1.5 mm along certain edges. They would not result in an accurate finish if used. The seatbelts which are paired with the canopy masks are up to the high standard I have come to expect however. Has anyone else had any fit issues with these or do I just have a bad batch? comments.....
  9. It just has to be an EE Lightning or a Jaguar!
  10. Thanks Kev and Brian, I’ll give that a go and see what happens..... ....ten minutes later and it worked like magic. Clear sellotape pressed on firmly, peeled back and it lifted the decal clean from the surface with no underlying damage to the paintwork. Thanks for the great tip. p-t
  11. Does anyone have any tips on how best to remove a decal from the surface of an engine cowling panel? The panel was airbrushed with Tamiya gloss acrylic and then clear before the decal was placed. Am trying not to ruin the perfect paint finish and fastener detail underneath. The original decal was printed out of register which only became apparent after drying and I am trying to redo the panel with a replacement decal. Thanks for any suggestions.
  12. Lovely job Miroslav. I just ordered the wet transfer stencil set , do you have any comments about the surface prep or application of the HGW transfers? thanks. p-t
  13. With the discussion about so called “oil canning” on aircraft structures and whether it should or should not be visible on model aircraft a little light bulb went on and harked back to an aeronautical engineering degree participated in, sometime during the last century. What we are talking about here is called a Wagner Tension Field .... Tension field theory describes the highly buckled (wrinkled) state of membranes or very thin plates whose boundaries are subjected to certain planar displacements well in excess of those necessary to initiate buckling. The present interest in tension field theory is because lightweight structures with stretched membrane components have potential applications in space. In addition, membrane structures which are pretensioned by internal pressure have application to lightweight portable bridges, protective coverings and various air cushion devices. The theory was conceived by Wagner (1929) [1] whose primary concern was to explain the behaviour of thin metal webs in beams and spars carrying a shear load well in excess of the initial buckling value. Such webs offer little resistance to the compressive strain component of the shear and the spar flanges must be held apart by struts to prevent collapse. In the simple case of rigid spar flanges and rigid perpendicular struts the stress field in the web in the highly buckled state is primarily that of tension at 45°. As the shear load increases so does the magnitude of this tensile stress field and, just as a taut string resists a kinking action, so too does this tensile stress field resist the out-of-plane displacements engendered by the buckling action of the compressive stresses; these opposing actions result in a decreasing wavelength along the compressive buckles which form at right angles to the tension field. Strictly speaking such problems are non-linear and their exact analysis presents formidable difficulties. However, within the framework of large-deflexion plate theory it may be shown that for large values of the ratio (applied shear strain)/(shear strain at initial buckling) the relation between applied loads and planar displacements and stresses again approaches linearity, and it is this asymptotic regime for which tension field theory is applicable. In this regime the flexural stresses and the planar compressive (post-buckling) stresses are negligible compared with the tensile stresses; the assumption that their magnitude is zero is physically equivalent to the assumption of zero flexural membrane stiffness, and it is this which characterises tension field theory: the membrane is envisaged as being finely wrinkled at right angles to the lines of tension. In general these “tension rays” are not necessarily parallel and the boundary conditions need not be those of pure shear, as in our previous example, but shear must play a dominant role in the boundary deformation because of the requirement that the principal strains at any point are of opposite sign. This requirement will be considered in greater detail later but it is clear that if the principal strains are both positive so too are the principal stresses, and if the principal strains are both negative the membrane is ineffective in carrying load. Having been around aircraft all of my professional life, I have seen enough to commend any kit manufacturer to simulate this effect on a model. Bring it on. Any WW2 large aircraft in service for a short while would begin to show these effects. Standing by for incoming rounds.
  14. 1/24rth too large? That is why Airfix provided the option to fold the Hellcat wings, just like on the carriers. Now there is the justification to yourself to buy and build it.
