  1. RAF Museum have posted a really useful cockpit 360 view of the Amndover on their Facebook page: https://www.facebook.com/rafmuseum/photos/10159054124882612 Great content for anyone building one of these... Iain
  2. I've used about 2kg of 1.75mm HIPS filament in total so far - including test pieces/failures and supports. I managed to get 18 x 1kg rolls from a company in Germany, via Amazon before Christmas, for an extremely reasonable £12.99 per 1kg roll - so cost at those prices about £26 so far. And they are a variety of bright colours - will all look the same under paint! However, that source has now dried up. Just checked and probably around £20 - £25 per 1kg roll now - so still under £50. Expect roughly another 2kg in filament for engines/
  3. Holy thread resurrection Batman! I think there's some confusion over just which March I last posted a B-17 update in - 2020 - not '21! I'm still undecided regarding whether I want to fix the outer nacelles, or not. And besides - model is sat at the office - 50 miles away - and I haven't been there much in the last year, some some reason... Iain
  4. And behold, Bob's your confused metaphor... Or, this is where we're at this evening. 61cm/24 inch rule for size: And the tail fin joints have been sanded smooth: More when there's more, I need to go and lie down in a darkened room! Iain
  5. Upper forward fuselage - with side observation windows and main entry door cut out from the CAD model: And with the cockpit section. This, like the other pieces, is double-skinned - but with no infill in-between - so I can easily strip down to a thinner skin and cut out the areas to be glazed. Printed in grey HIPS to make things easier with regards to colours and window fitting: Obviously, these parts go down to floor level - which should simplify things later. Hollow nose cone: And t
  6. That's brilliant Mike! Great to see it with a wing on - I think it looks really good. Wings are next for me to look at - going to see if I can thin the trailing edges on the .stl files before I slice/print - and probably remove the control surfaces. It's fun being just slightly mad, isn't it! Iain
  7. Item the next... Forward lower fuselage - with the area around the nose gear bay cut out ready to add a suitable bay at some point further along the build: Ready to add to the section behind. Like the gear bay area, I've cut out the top of the well for the retractable MX-20HD electro-optical/infrared sensor turret. An opening for this was already on the CAD model - but was capped off - and caused a previous print to fail. Opening it up allowed me to run tree supports in from either side of the part to support higher print layers:
  8. OK - latest parts: Ignore the surface marks - that was me whipping over some of the parts with some wet and dry paper - surfaces are actually really good straight off the printer - but will take some surface prep to smooth out the layer lines. These are easier to sand off than ABS prints... I mentioned that I was pleased with the PEI bed - and print settings - no shrinkage and perfectly flat base surfaces (any curves on straight edges are camera distortion on the wide-angle lens): The horizontal cuts are in
  9. Sorry to see that! Doubt it's Tamiya/Mr Hobby compatibility (if both aqueous/alchohol based?) - I mix them all the time. *Could* be that layers haven't sufficiently dried off between layers (I leave mine for days at least - sometimes weeks) - or possibly decal solvents not dryed/cleaned off properly (I've had similar happen because of this). Deep breath - and, maybe, a large whisky - you might be surprised how much can be made good as new with some careful touching in, and a light varnish... Iain
  10. I think Tim's being a little too subtle there... I'm loving HIPS as a print medium - and getting superb results now with the printer settings all dialed in, a PEI bed and the enclosure. The material is absolutely perfect for our purposes - but it is sensitive to temperatures - both printer and ambient. Inside the enclosure it's mid 30's deg. C (90's F) whilst printing - and I've learned to let everything cool very slowly to room temperature, before opening the enclosure and removing new parts from the bed. I now have a suitable thermometer tie-
  11. Looks like it'll be a useful set - it's on my shopping list... Iain
  12. Just a thought re size: I'm sure a lot of the thoughts around size are because, traditionally, the static scale models side of things has been smaller scales/model sizes - compared to the model flying/Radio Controlled hobby, where large model airframes are the norm. This project really isn't that bad when compared to those flying models! OK - perhaps I'm trying to rationalise the project, or maybe not... Meanwhile, another section on the printer after a support failure yesterday - should be finished tomorrow am, but will try and get some photos of the othe
  13. Connie will be back on the go soon - the 3D Print side of things will form a core part of the next stages - now I have the tools and am gaining experience. Because it's usually raining over here! Iain
  14. Someone on our modelling club's Facebook page asked how the 737-800/P-8A Poseidon compared in size to my other big project - the 1:32 Lockheed EC-121 Warning Star - so some images for anyone interested! As I've mentioned - I will be using my printers for parts for the Connie too. Iain
  15. In answer to the earlier weight question - I've just weighed the fuselage/fin as is the above photos and it's 1.22 kg - not bad at all for something this size - a vac with the necessary internal reinforcement would weigh at least that I reckon. Obviously, more weight to come... OK - so, yes, it's very, very, silly - but it's currently dominating the table in the living room - and it's a pretty impressive thing to see, if very slightly mad. As an exercise in 'can I print something big' it's worked - and taught me a huge amount in the process. Iain
