  1. Marks' Models in Hawkins Street, Dublin. The perfect basement model shop CC: https://maps.app.goo.gl/HALzf2kbEGyKC49c6 Zaitoon near the Grattan Bridge for a perfect Shish Kebab after! https://maps.app.goo.gl/9FK2cVrgBzHxua2aA Or Ryleigh's down along the North Quay if you're feeling a bit more sophisticated and fancy a rooftop steak and cocktails looking out over Dublin Harbour: https://maps.app.goo.gl/ojcmVrEe7T5Nd8CZA
  2. Pretty sure that there are collectors out there more than willing to pay good coin for workmanship of this standard on such a beloved icon. Just superb Alan. Congratulations.
  3. It will do after two more tequilas and a lie down. Seriously Pete, you know my perpetual fondness for your visual riffs and this project is of the usual high standard of inventiveness. Great work.
  4. β€œYou do not have to say anything. But, it may harm your defence if you do not mention when questioned something which you later rely on in court."
  5. Mark: I have to say your paintwork on that IP is top drawer. An absolutely compelling representation!
  6. I once heard somebody at work refer to 'going the extra mile' as 'fine if you live more than a mile from a cliff'.... As a sculpting environment it's basically designed to do all those organic/irregular things that CAD (and most 3d packages) can't handle Ian, so most useful in instances like this. Cheers as alway Bill. More than happy to print you off a couple of cushion backs at 1/72 in the next print run, as long as you don't need them urgently? Kind of you as always Chris. Thank you. Pretty sure that sentence would read differently to American eyes! Simply a reflection of my physique by this stage of life pal. If such a cafe existed they could just take my money...
  7. Morning all. Writing from beneath some very energetic skies at present: Oh Mighty Zeus &etc. Hopefully that gave you another data point in order to isolate the problem Ian? If it's any comfort I absolutely hate dialling in resin/printer combinations. Probably not Colin; I might have got carried away. Actually there was originally a reason but having failed to write it down at the time I now have to think about it in case it's important.... 😁That sounds like one of those Doomsday machines that would melt itself down the moment the heating element is switched on.... πŸ”₯ Mercifully I have a dental vacformer picked up cheap in a sale years ago. A test vac was actually ready with some scuzzy scrap PETG a fortnight or so ago. The reason for doing so at this point is that , before proceeding to print any more bucks out I need to an idea of how much to reduce the prints of them by (i.e., taking into account the thickness of transparency along with any dimensional shrinkage in the cured buck). This is vital so that the vacformed transparency fit accurately into its allotted place on the kit. You can see in the shots below who was too busy yacking to the missus about what to have for supper and let the PETG get too hot and blister!! Cosmetics aren't important for this test shot however as it's only the tolerance of fit that matters. Rather to my surprise/pleasure, the guesstimate used proved within acceptable bounds: This particular part was selected to test as the complexity of its compound form in three dimensions would readily reveal any flaws in shape and scale. With the vagaries of the material process involved, such a task is always going to be more of an art than a science of courses, but in terms of buildability I'm satisfied that the reduction value used here will work for the 1/24 version. I did do a 1/32 vacform at the same time but haven't got round to testing yet if the same reduction in size is ok for that scale too: Calling this shot 'Imagine'... As you would expect, commencing work on the inside of the cockpit/cabin requires a lot of planning and familiarization for one as ignorant as myself of helicopter functionality, so started with this simple drawing: - which quite rapidly developed into a series of interdependent features, any one of which will give itself away in relation to its surroundings if inaccuracies of shape and size are present: In such situations where things are a bit overwhelming en masse, I usually just pick an end and work doggedly backwards or forwards from there - in this case starting at the (simpler) rear of the cabin with the three person bench seat: I'll be printing this up as a bare framework sans canvas covering for two reasons: the first being that the thinness of the fabric means printing it at scale would require an exagerrated thickness that would look wrong, and secondly, it's nice to leave something for the modeller to have fun addressing with their own creative choices regarding materials. A bit like tailoring, I will produce a paper template of the fabric cover for my own use first, so may include one in the instructions. The underlying framework (not easy to work out in photos due to the fabric cover and limited photographic angles) is a simple and robust, consisting of two legs mounted into recesses in the cabin floor, with a set of 'claws' attaching to framing on the cabin wall: Despite being sure that the bench has the greatest enthusiasm for the mission, I suspect the eSun Hard Tough resin may be required to print it on grounds of strength - particularly at 1/32. Mounted directly above the canvas bench itself is the padded back support cushion (absent in many shots of surviving airframes) affixed to the bulkhead via a set of fasteners. Producing this turned into a bit of a handful, again for two reasons. One was to do with the shape of the cushion itself (due to the complicated profile of the cabin wall and the way that this part has to fold around it) whilst the the other is simply that as a CAD package, Fusion 360 is highly unsuitable for trying to design more complicated organic shapes like cushions etc. i.e., those which show the combined effects of use and gravity on non-rigid materials over time. I know there's the 'Forms' section in Fusion as I've used it for smaller organic shapes before, but it's not up to a job of this nature. After much deliberation I decided on a two step solution to the problem. Firstly I created an accurate - but far too rigid in the raw state - version of the cushion in Fusion: For something like 1/72 this would probably do quite happily: - but for larger scales, that appearance is far too pristine and regular in being devoid of the irregularities and sagging tof an item in regular use. There was going to be no substitute for sculpting such effects so after exporting the part as a high res mesh, I imported it into ZBrush to spend some time learning how to develop the preliminary design into a more convincingly used/saggy looking respresentation of the cushioning: Luckily I had one particularly clear and well-lit photo that provided all the necessary effects which had to be visible (eg. sags/dents/pinches/folds) but it did take a while to become familiar with all the various scultping procedures available in order to be able to reproduce them. When comparing the original (top) with the 'used' (bottom) version treated in Zbrush, the cumulative effect of these irregularities is I feel a more satisfying reflection of the real thing: In a fit of hubris I at one point used a sample of the actual leather texture from a photograph of the rear seat of a Wasp in order to create a seamless brush in ZBrush to apply as a surface texture: - an endeavour as foolish as it sounds due to the texture even at 1/24 being so fine as to be invisible - a pointless to attempt. A quick render using the rather naff 'leather' texture in Fusion though and it could be the greatest cover The Velvet Underground never had for 'Venus in Furs'... 'Shiny, shiny, shiny seats of leather'... A view of the rear to show how the part has to fit around the the features of the cabin wall (some of which provide useful mounting/registration points): The following two renders of the collective appearance use the original 'pristine' cushion as the mesh for the Zbrush version is too big (in memory terms) to introduce back into into the already memory-hungry overall design in Fusion: It doesn't look a lot in relation to the time it took to produce but having to learn new software was unavoidable, especially when thinking ahead to the two front seats that will need similar treatment in turn. I wonder how good Zbrush is with sheepskin? As for the next stage, it seems prudent to move on to the central cockpit console, lying as it does between the two seats and supporting the IP upthe front. Having the basic outline of this blocked-in gives a good basis to proceed with the seating on either side. In this way, producing the largest features first and working downwards in size should - hopefully - allow for overall accuracy and a controllable way of introducing smaller and smaller levels of detail over time Hopefully.🀣 Thanks for reading as always.

  8. Hi Pete! I'm not anticipating problems on either count tbh: I find polishing resin bucks with the Dremel and polishing compound produces a nice mirror-like finish whilst the buck walls themselves are thick enough to avoid structural integrity issues. That's a puzzler Ian. It looks as if the resin has failed to cure on portions of the right-hand object but this is not something I've encountered before. I know you use the Mars 4 - with which I'm unfamiliar as to any idiosyncracies - so all I can suggest in such a situation is a diagnostic to isolate whether the problem lies in the printer or the resin. In this regard I'd print identically-oriented parts with a different resin - something cheap like Elegoo's standard grey should suffice - to see if the same error recurs. If it doesn't, that would point toward a problem with that particular Siraya resin in relation to the printer, if it does, it would likely be a problem with ether the printer, or print settings. Apologies my friend if you've already done all that and I'm simply teaching my Dubai grandmother to suck eggs...
  9. As it should be. Glad it's working out Pete!
  10. Very kind of you as always G. Many thanks Bill: it's taken a while to get round to posting it up as I kept finding another flaw just at that point when you think you've caught them all. Gives you a whole new level of respect for those who have to do it on the real thing! Cheers T. I'd be lying if I didn't admit that - for reasons I'm not entirely sure myself - those carriers were a source of personal satisfaction. The various racks and carriers on period aircraft always draw my eye - possibly as there's something very Victorian-engineering about their structure that persisted into the modern era... Generous sentiments from you as always Chris - my thanks. Sincere thanks. It often - not out of any personal hubris - amazes me that we can make these kinds of things ourselves now. Being of a certain age I grew up with this kind of 'materializer' idea as a well-worn scifi trope. Thanks Colin. Yes, we're of a like mind on the glazing - vacforming is the tool of choice. I've the bucks designed: - but as it'll take a while to dial-in how much allowance to make for shrinkage and cross-section of the transparent material, am only in the early stages of test-printing the bucks for both scales: N.B to self: remember to write the reduction factor on each one. With regards to the roof windows - this is a downright frightening image: Actual operational incidents here, complete with an unorthodox submarine recovery procedure... https://hmsnaiad.co.uk/naiad_flight.html Gracious of you Kev. My thanks; and decent of you Neil to avoid appending 'of aberrant obsession' at the end of that sentence! Cheers Simon. It seems to be a universal law that the closer you get to the end of a project, the more it seems to slow down so that you think you'll never get there... 😁 Kind words and nice to feel missed Pete. Likewise fond felicitations to yourself. How's retirement treating ye? Cheers Ian. That's interesting about the nature of the problem with Siraya stuff: I've only used their purple and blue Tech Cast stuff for metal casting so no experience to draw upon with their ABS I'm afraid. Odd that the flaw exists between supports - could you post a picture of the issue? For the main parts like doors, torps etc. in the previous post I used Elegoo's 8K Space Grey resin: at a 3 micron layer height (and slightly under-exposed) the stuff gives beautifully crisp renditions of the CAD designs. For larger surface areas with sparser detail like the rear fuselage/boom assemblies I still use Elegoo's standard grey which I've been using for years. Anything printed in black is using eSun's hard Tough resin for extra strength. That's very kind of you to say so and I'm grateful. Cheers Dave. To end: reading about Hawkwind recently - only saw them once at the Hammersmith Odeon in the early 80's - but what is possibly the most-Hawkwind anecdote ever regarding one of their solstice gigs at Stonehenge during that period: (Source: The Saga of "Hawkwind", by Carol Clerk.)
  11. 1/6th of the way round the sun since the last update here and I'm shamelessly blaming interstellar debris as an excuse... (This - interestingly enough - from an issue of Flight magazine published in the early 50s.) Work on the Wasp has in fact been continuing in the background of the business of living in these times, so best to recount some of the key developments before what's happened and why get lost in the fog of the now. Essentially I've been gradually working my way through the plethora of parts which amassed in CAD form over the past few months and which were long-overdue for translation into solid objects. Due to the combination of extreme thin-ness and compound curves on things like doors and so forth, this required a lot of troubleshooting with resin types and orientations in order to maximize part strength and avoid striated surfaces due to poor orientation of such curvatures in space. It also took a lot of customization of support types in VDT, which I have to say has proven itself a godsend for the variety of shapes involved here in terms of facility. Here are the final results of all these various print runs en masse: And lest anyone gain a false impression that over time you ever get good enough for your efforts to succeed first time on more than a single part, this rarely rarely happens as the image below demonstrates in terms of the the level of failures required to iron out flaws and reach that point above: The usual caveat applies to the following images in that they are shown freshly printed i.e., resin washed off but none of the print-support stumps sanded from surfaces. The design of the rear wall of the cabin was revised in Fusion compared to the printed version shown here in previous updates, in that it now has the angled rear-window panels on either side of the central panel integrated into the one design: It turned out to be feasible in the end to print these as one component and will, I think, prove a more accurate solution than trying to glue them on separately at the right angle during assembly: All of that surface details remains present in the 1/32 version shown below as well, so my guesses about minimum feature size in the 1/24 version to survive scaling down seem to be holding up pretty consistently across the model so far: Pretty much the same for the doors; both front: - and rear: - retaining equal levels of detail when scaled down to 1/32: Door pillars too will look even nicer with the naviagtion lights installed later: Too fragile to reproduce in 8k resin, the sliding windows for pilot/obervers had their frames printed using eSun Hard Tough resin: Again the 1/32 version of these also survived the Alice in Wonderland treatment and printed as well. Amongst a number of other components requiring the black eSun resin for strength were the jury struts onto which the floation gear attaches as the front: On the 1/24 version shown here you can see from the translucency down the sides just how thin the edges of that I-beam shape are. In this view below the translucency also betrays how thin the walls of the recess which the float gear struts fit into are as well - even after I added a small reinforcing panel inside of there on either side: These features also reproduced at 1/32 quite pleasingly: - however the walls of the strut recesses were just so molecularly thin at 1/32 that it necessitated them being largly filled in as a compromise between being present but not causing the print to fail in those regions (as it had done in tests): Driveshafts from main to reduction gearboxes were also done up in black stuff as they'll be helping to support and align the entire engine/gearbox asssembly later on: The rear cabin framing at 1/24: - and at 1/32 both required the stronger resin to avoid breakage during kit assembly: I wasn't sure if the door handles (on the right end) would work at 1/24 but they did: More improbably however they also printed at 1/32 using the smallest feasible tree support I could devise in VDT: Enormously pleased with how the nose parts came out in the 8k resin at both 1/32: - and 1/24: Some residual striation around the drain holes (necessary to avoid suction issues during printing) on both to tidy up at the same time the holes are filled. Detailing along the top surfaces was everything I hoped it would be, despite my heavy handling during support removal resulting in some breakages along the cheek window guttering (though these are easy enough repaired with some tape and the UV laser): Underside and RADALT enclosures: The weapons loadout had some attention in the form of prints for the Mk44&46 torpedoes: Mk.44 first - this performed nicely at both scales: I wasn't worried about support structures for that annular feature at the rear on the 1/24 scale: But VDT came through again in allowing for some very fine structures to support it at 1/32 scale without causing undue damage to the torpedo casing in the process: I just noticedthere's still a revision to do there at 1/32 as you can see the supports for the fins themselves weren't strong enough. The propeller assemblies of the '44 at the smaller of the two scales: Mk.46 behaved itself equally well at both scales, with no features failing: Parifcularly pleased with part definion on the props for both sets, 1/24 looked nice: - yet 1/32 turned out far less of a problem than I'd feared in terms of effective support processes: The same story regarding all the fiddly detail on the carrier racks and sway braces which took so long to do up in CAD: in printed form there were no features missing or compromised at either sale (shown here at 1/24): Suspension bands on the torpedo bodies also nice and crisply rendered: Also added to the pile at this time were the landing light assemblies and transponders in both scale: Fairing seen here in 1/24: With no detail absent from the 1/32 version in relation to its larger cousin: For reasons which as modellers I hope you'll understand, I couldn't resist doing a mockup of the Mk.46 torp at 1/32nd scale the other night, 'just to check' that the parts fitted together Ok: Over the weekend I sat down and drew up a snag sheet for all the parts still needing to be designed in CAD: The bulk of this as you can see involves the cabin & cockpit interiors, to whit I have the reference mosaics done up ready to start preliminary sketches for those areas: Particular thanks need to go to @Ex-FAAWAFU, @Terry1954, @Anthony in NZ for imagery of the interiors which they've shared with me from their collections that will prove invaluable in the next phase, as well as all those positng stuff in the BM Walkaround for the Wasp. Thanks for reading as always and hoping this finds all here in good form. Tony
  12. Glad it was of some encouragement Lee! After the first flush of success as it were, over time I came to find the amount of work it took constantly tending the above arrangement to get 'good' i.e., usable for modelling purposes overly time-consuming, so took the plunge late last summer and invested (no pun intended ) in a proper burnout kiln for the studio. Now it just works away in the background whilst I'm doing other things and rarely a fail. I got mine from Tuffnell Glass over in Yorkshire; Martin there is a very nice guy to deal with. Best, Tony
