  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
  16. That really is a thing of beauty - love it! Iain
  17. Slow progress - but with the latest fuselage part off the printer I was able to tape everything together with the earlier 737-800 front end and gauge the size: Note the cut out sections for main gear bay and weapons bay. It certainly has 'presence'! Printer is busy on the next sections - broken down to facilitate doing an interior from the side observation windows forward... Iain
  18. Congratulations Gramps - brilliant news! Fury is looking stunning... Iain
  19. Call it 'Lockdown Fever' Peter! But I do think it's all doable and, size/transport/storage/painting aside - not that impossible a project. As I said: this is my 3D design/print test piece/apprenticeship and the project gives lots of opportunity to learn and push my skill-set - which is the driving factor. Oh, and something very different! Some more parts off the printer yesterday, and the next fuselage section is currently half-way through printing - due to finish around 5 am tomorrow. Iain
  20. Which reminds me that I need to extract a digit and review the Quickboost blades and Vector engines... Iain
  21. In my case I've not the finished the wing on mine Greg - I'm still working on CAD drawings for the cores, to be 3D printed. If you go back to earlier posts you'll see photos showing the difference in cross-section and thickness towards the tips - I don't think I have any showing the wing against the fuselage - but, yes, IMHO it makes a big difference and is clearly visible - to me. I've seen models build straight from the kit and they look good - the difference is down to whether you, personally, want to make the modifications. It's your model and you should
  22. Looking good! Thanks for sharing the images. Iain
  23. Agree with file - I just want to be capable of doing my own designs from scratch - but I was really taken with the overall look of the 737 model when I first found it. As a blank canvas it's a great start! I've been doing quite a few changes to the parts using Meshmixer - so cut out gear bays, windows etc. - I *think* I can thin the wings/tail surfaces prior to print - but I haven't got that far yet. As to working together - absolutely! I'm way behind on the design curve - but more than happy to share anything I create between the three of us.
  24. Weight - the slicing software that takes the .stl files and makes them ready for the printer gives a printed weight for each part - but that includes supports which are necessary for a successful print, but will be removed and discarded. I'll do a post over the weekend with weights so far - and showing the internal structures the software creates - I find it all fascinating... At a rough guess I reckon the complete fuselage/tail will be around 2kg (4.4 lbs) - or slightly less. For it's size (approx. 1.2m/4' long) that's pretty light. Yes - the un
  25. Aren't we ALL a little crazy in this wonderful hobby of ours? Sanity is SOOOOO overrated (as I've probably said before)... Iain
