hendie Posted October 1, 2021 Share Posted October 1, 2021 Challenging and not for the faint of heart, but you've got form for this type of stuff Bill, so I'm not unduly concerned. Concerned? No. Drooling with anticipation?, yes. 1 1 Link to comment Share on other sites More sharing options...
perdu Posted October 1, 2021 Author Share Posted October 1, 2021 I'm trying but it isnt promising, cockpit details I mean. You may recall I went in search of the rotor brake at Hendon, and even with diligent searching I couldn't find one? Well I contented myself that the rotor brake function could have been a factor imposed by using the basic rotor head gearbox a passage in a book said was automatically engaged or disengaged. Seems not if this passage in Borneo Boys is to be believed... Time for more research huh? I wonder if @bootneck could find it out for us at Weston On The Mud? I will have to ask him, in the meantime some more innards work has been begun. Basic floor and rear bulkhead in. And confirmed to fit. The first diamond pattern soundproofing added to the back wall prior to adding the bits that sit atop it all. A photo I have shows the diamond patterned stuff to be silvery but it won't surprise me if green gets in here someplace. The buck I moulded the canopy on my other Whirly has surfaced exactly where I expected, I have been repolishing and reshaping the resin buck. Fairly happy with this That looks fair to adequate, par for the course anyway. 7 Link to comment Share on other sites More sharing options...

I'd love to see what Tamiya could do to a Walter or a Sea King. Aerodynamically challenged? Wash your mouth out, young man! But if Tamiya were ever to issue a 1/48 (or bigger…!) Sea King a) I would eat my hat and b) I’d be in heaven. I am shamefully late to a new Billocopter, so please forgive me. If I understood your question right, Bill, I cannot think of why anyone would want an automatic rotor brake; definitely applied / released by the pilot. 3 1 Link to comment Share on other sites More sharing options...

perdu Posted October 2, 2021 Author Share Posted October 2, 2021 Terry Postimg does do that occasionally nothing I can do but tell you I am still seeing them on multiple devices, if they are still missing maybe Mike the Owner's advice of clearing the cache could do it. Sorry mate. I have this picture in my stash Obviously (from its title) a restoration job at Long Marston, it shows the cabin roof structure rather well if you peer into the shadows I know there is a flat structure under the rotor gearbox but the rest of the roof bears the arch structure I tried to dummy up last time around. Pshaw, utter junk, I mean it doesnt get close But gave me a basic for the rotor's main gearbox to sit on. I am not doing it that way this time because I need to get the entire airframe looking right to my own eyes before I pop a roof on it. The Airfix cabin is a touch truncated by the mis-shapen tilted cockpit cover, so to make it fit right this time I decided to make the curved roof go all the way back in a strong arch that I can close off properly. With a better MRG structure. Donor sections were sought. The roof behind the crew seats needs reinstating as an arch, how to do that huh? Oh I know find a tubular structure with a suitable radius, how about that fuel tank from someone's random C130? Cut out a suitable length of tube shape, no, not a wide enough radius. Beggarit! But there is a suitably shaped, modifiable donor in the box just there, but doomed to make Crisp hate me again Yes the old Airfix Sea King nose donor which has since been a general purpose paint mule and dogsbody has a pair of suitably curved shoulders. They gotta go in the Whirlybird and a suitable piece was butchered for the cause. This section is going down into the garage for tube glue attachment then I will leave it to set hard. Ciao dudes. 9 Link to comment Share on other sites More sharing options...

Sorry mate. Looks like it's down to the OS version on my Mac, not Postimg specifically. My Mac OS went out of support at the turn of midnight on 30/09. It's also stopping me seeing Scalemates now from that Mac, and probably over the colurse of time others, but I'm typing this from my small Windows laptop, where all is well! Need to sort that Mac! And so now that vision is restored (although this laptop screen is much smaller) I can say that this complex buck work is impressive, and now we are even using a Sea King doner nose no less! Great stuff Terry 1 Link to comment Share on other sites More sharing options...
perdu Posted October 2, 2021 Author Share Posted October 2, 2021 No don't tell Crisp I'm using a nose please, this is a redundant upper fuselage from an already dead one. Tell him that and I can envisage getting a kick from Das Boot, not looking forward to that I tell 'ee. This is the structure I am going to fake up, seen in a rather sad picture of decay. As you see it needs a bit of fabricating but it's going to be far better this time. For all my most diligent searching I still haven't seen this gottverdamte rotor brake though. Fake it with a pseudo roof handled doohdah like the Wessex has? Might have to if I don't get the real thing by, maybe Tuesday. 3 Link to comment Share on other sites More sharing options...

hendie Posted October 2, 2021 Share Posted October 2, 2021 sheesh. You're taking no prisoners on this build are you Bill. A good move though - that choice is going to give you what you're looking for internally as well as providing a sound base for the rooftop works later on. 1 Link to comment Share on other sites More sharing options...
perdu Posted October 2, 2021 Author Share Posted October 2, 2021 This week's edition of "What's stirring down in the lab?" includes How Far Can You Stretch An Idea? And How Far Should You...? Also in the lab today How Clear Will Resin Stay If You Do It Harm With Abrasives? First off cure some window experiments with Limino Clear resin, then illuminate... Then attack with abrasives to see how hard the windows got, One window was the oddball effort from Airfix with built in dents and ripples the other a piece of CD case, thanks to @CedB, cut and filed to fit the enlarged (I had to move it forwards, remember?) back window panel. Both were infilled and backfilled with the resin so I can give polishing resin a try, having been significantly useless at polishing superglue under the same conditions, we shall see For the canopy moulding I used a pull technique rather than 'plunge' but feel free to refer to either name. The working version will be PETg I think, 'acos I am almost out of the favourite thin acetate packaging material. Crusaded digits time methinks. 🤞 7 Link to comment Share on other sites More sharing options...
perdu Posted October 2, 2021 Author Share Posted October 2, 2021 Found it! The rotor brake is fixed to the input shaft to the main rotor gearbox and operates with a lever on top of the centre console. Or so it says on a Flight type diagram I just found. Pictures coming tomorrow. 4 Link to comment Share on other sites More sharing options...
Terry1954 Posted October 2, 2021 Share Posted October 2, 2021 That is impressive pulling (or plunging) Bill. What thickness acetate was it, and what thickness PETg might you use? Terry Link to comment Share on other sites More sharing options...
perdu Posted October 2, 2021 Author Share Posted October 2, 2021 It was just 'thin acetate' Terry but I will have to use 0.3 PETg, tomorrow might be interesting... 1 1 Link to comment Share on other sites More sharing options...

perdu Posted October 3, 2021 Author Share Posted October 3, 2021 I did say the rotor brake is on top of the centre console but that is slightly incorrect, it's a lever on the side of the console (with gurt great label on it ROTOR BRAKE) with a Y shaped handle on top seen here alone on the image of a single pilot machine's cockpit. This one looks as if it might be a reddish plastic handle but in RAF service they seem to be black material Black to the newer machine, this seems to be a civil operated Whirlywind. SE-HGZ? Did I say newer? Built in 1958!😲 When I zoom in on the original picture I can read rotor brake on the legend facing the crew, I am happy with that. It goes in the 'pit painted black so we dont see it... 7 Link to comment Share on other sites More sharing options...

perdu Posted October 4, 2021 Author Share Posted October 4, 2021 I am not going to include invisible at this scale ribs between each stiffening strut, so here is my lower front bulkhead about to take up its forever home. This will do for in here I havent mentioned the Airwaves set yet ('cept in passing) and I am not sure how much of this will get in the game but the floor with its proper sized cutouts is a definite. So the forward depth of the bulkhead is decided by my mate Andrew's work back in the eighties when Airwaves were attempting stuff nobody else had. Cheers Andy. The upper bulkhead and fuselage roof portion will be measured off the back of the foot hole positions, then I will build the innards and MRGB and fit out the controls. Airwaves even gave me yaw pedals with the proper brake pedals on the etch sheet. 8 Link to comment Share on other sites More sharing options...

perdu Posted October 4, 2021 Author Share Posted October 4, 2021 This looks good so why dont I want to use it? Anyway, all that gubbins isnt right so of it comes. Now where are we? Oh yes, upper fuselage roof completion ahead? Well maybe but still no cigarillo? OK, es possible no? Er no... The lovely semisculpted rear panel sits much higher than that in real life. Try this with a reduced height panel. Looks much better, how about from where alone it will be visible? That'll do, paint the innards soon after finishing the cab for the crew. Cockpit next. 7 Link to comment Share on other sites More sharing options...
Brandy Posted October 4, 2021 Share Posted October 4, 2021 Looks much better, but the lower surface of the central beam is not a straight line all the way, it flattens off for maybe the rear third of its length. I know you want it right.... Ian Link to comment Share on other sites More sharing options...
