perdu Posted October 21, 2022 Share Posted October 21, 2022 Even I dont look for all the pipes Tony. Nice to see that sophisticated Rotoflex coupling on the drive shaft, wish I'd had those for my various Imps that developed driveshaft coupling failure... More stupendous work Tony. 2 Link to comment Share on other sites More sharing options...

And finding it an inadequate aid to comprehension; given up trying to understand what you’re doing and resolved to just be thankful that you’re doing it and letting us in on the process…. Thanks: hope the coffee was good Steve. I think I know what I'm doing (with the Wasp, not life in general, just to be clear), but as to the why, well, that's a source of constant speculation. I may have been deprived of helicopters as a child? You'll recall me bleating about wanting to build a torpedo-toting version of the Wasp whilst ruing the necessary exclusion of the missile sight. Well, there I was last evening disconsolately leafing through the webpages of the HMS Ambuscade Association (we've all done it) when I found a photo of their Wasp running with torpedo, flares and APX/BEZU sight all clearly fitted together at the same time. I can't embed the photo as their albums are protected but the image in question is this one: http://www.ambuscade.org.uk/Images/Slideshows/David Marchant/album/slides/scan0025_jpg.html In fact David Marchant's crew page from which it is drawn is a treasury of period 1970s photography, almost bordering on photojournalism/social history in the way he captures people and events: http://www.ambuscade.org.uk/Images/Slideshows/David Marchant/album/index.html As well as his excellent description of Ambuscade's helicopter operations here: http://www.ambuscade.org.uk/am_sea_ops_Flight.htm You never know what you're going to find do you? So glad to have discovered David's references buried away in the Association's pages like that, making this now officially Wasp XT778 ('323' in the period 1976-80). 😄 Nimbus update to follow later this evening..... 9 Link to comment Share on other sites More sharing options...
Pete in Lincs Posted October 24, 2022 Share Posted October 24, 2022 Result! I'm really happy that you now have a definite 'target' so to speak. Looking forward to more, and I'll have a butchers at those links. 22 minutes ago, TheBaron said: I may have been deprived of helicopters as a child?

TheBaron Posted October 24, 2022 Author Share Posted October 24, 2022 Figuring there were too many other features of the engine deck that have to line up with another it was time to take the plunge and begin work on the Nmbus itself. The main 'core' - as it were - from urbine, forwards through the bulge of the combustion chamber and axial compressor up to the forward intake was a relatively straightforward matter of using a dimensioned drawing to revolve a profile from: - which in turn (no pun intended...) lead to a relatively straightforward panic attack upon realizing that the wide mouth of the air intake up front then completely buries the three couplings sticking out the rear of the MRGB! That is, until you belatedly check your references for yet another instance of not seeing what was staring you in the face the whole time, which is that the intake does indeed cover up the oil and hydraulic pumps on either side unless you cut the required sections out of it on either side like the real thing: Image credit: Graeme Molineux Lacking any manual for the Nimbus but posessing a digital copy of RR's brochure for the engine (which contains some excellent technical drawings and a table of dimensions) was also most useful in confirming those cutouts to the lower qudrants of the intake: If I bung the MRGB back in for a moment you can see the kind of clearances we're talking about under there: Pretty tight! I haven't worked out yet what some of these fittings are for around the rear of the intake but that long feature mounted at an angle halfway up appears to be a level gauge - perhaps for engine oil? Tucked away under all the components bolted around the Nimbus are a ribcage around the compressor up front and a trio of rectangular features around the the turbine drum down at the rear: That and a whole shed load of bolts.... I see I've missed a ring of them in that shot. Bugger. The Westland lads went a bid mad with the ruler and compass on this bit to be honest: Bolted to the turbine drum, this cradle provides moubting points for the reduction gearing and output unit that sits below the exhaust: I've just blocked those latter units in temporarily here with some basic cylinders to aid the design work on that cradle; there'll doubtless be some back and forth involved when tweaking the relationship between those two structures in terms of aligning specific details later. 52 minutes ago, Pete in Lincs said: Whereas I have a memory of playing with the Scalecraft Wessex.

Anthony in NZ Posted October 24, 2022 Share Posted October 24, 2022 Great choice of scheme and load out...Gonna look amazing! I am hearing back from the Museums collection manager today as to a time to do some measuring for you. How are you off for the flotation devices, need anything measured etc there?

If your tape were able to drape over any of the following areas, that would be enormously helpful: Rotor blade breadth/width (tail & main) Width/length for that big floation gear lozenge and struts would be most helpful. Wheel hub diameter Width of tailplane Width/height of pilot seat/back Any dimensions you can get for the torpedo mounts...

Terry1954 Posted October 25, 2022 Share Posted October 25, 2022 Excellent news on the Ambascude Wasp loadout. What were the chances of finding such a shot! Always liked the lines of the Type 21 frigates and I recall how futuristic they looked to my eye when they first appeared. I think I built my way through a couple of the old Airfix Amazons. Very nice work indeed on the Nimbus. A masterpiece in its own right. Terry 2 1 Link to comment Share on other sites More sharing options...

perdu Posted October 25, 2022 Share Posted October 25, 2022 Masterful it is, isn't it? Have a delighted wow from me. This image has me almost drooling, so detailed already Saved already for my nefarious purposes I did wonder if you were going to do as much to the drive shaft then I realised you had stopped it in the right place to add the coupler sleeve to the rear bearing. Studying that in my set of archive Scout photos (same device children!) I found a smashing shot of the coupler with a metal data plate wrapped round it Bugger, means I have to try that in 72th scale for my next Scout. Yup next! Found this and a few other relevant pics in said archive if it is any help. Let me know if they'd help Tony 6 1 Link to comment Share on other sites More sharing options...

WHEEL Hub dia =200mm Tyre dia =375mm Tyre width = 120mm Fork width =225mm This is outer face of wheel Inner face Inner on other side of fork Ok, on to decipher next load.
