evening ladies & thank you :)

 

have been sorting out more of the basic structural elements so ultimately I have the airframe ready to skin in one (long) go, rather then the Spitfire where I did it bits at a time and had trouble protecting finished work as I did some pretty violent things like those I am doing now...

 

starting with the tailwheel well - I started byu cutting just the doors out, but soon realised I could not detail the inside through the small aperture - I won't go mad in here, but I will replicate most of what I can see - here is the real (current) Lopes Hope..

 

WIP538_zpse4vtpel3.jpg

 

..I started by cutting out the section between two fuselage stations in between the whole structure and getting rid of all the solid foam inside - painted it black so none of this is seen...

 

WIP540_zpsnvfjay57.jpg

 

..then from many scaled plan parts I assembled the main structure from litho, with brass strengthening where the wheel leg will mount...

 

WIP539_zpsxrenvuuw.jpg

 

..added some details and skinned the sides of it so it can drop in as a complete pod...

 

WIP541_zpsuiawerdy.jpg

 

..this was then added and CA'd into position ready for the fuselage section to be added back & filling..

 

WIP542_zpswk6qx4ry.jpg

 

..and after cleaning up, the basics are in there I can come back to later..

 

WIP544_zpsnnggaekx.jpg

 

..I also added the airscoop and got the shapes in this area where I was happy with them..

 

WIP545_zpsxmaxycee.jpg

 

WIP543_zpsx4ygzrkj.jpg

 

..the next bit of surgery was around the wing fillets - they seem quite complex on a P51 with the top edge sitting over the flaps and a lower fairing cut away right back to the fuselage wall..

 

WIP546_zpsjolvlsft.jpg

 

..the moulded fillet is a bit ugly and will need quite a bit of work..

 

WIP547_zpsrjm5meug.jpg

 

..I made a slit in the fuselage and added a brass template from a scaled plan - I also faked a flap from bent litho so I could get the dimensions right...

 

WIP548_zps9kbghot9.jpg

 

..then lots of filling & shaping and trying hard to work around and not damage the skinned part of the airscoop...

 

WIP549_zpsl5b82pzv.jpg

 

..and finally after a shot of primer to see whats what, the basics seem to be coming together...

 

WIP550_zpssr8oeep1.jpg

 

WIP551_zpsakfksuha.jpg

 

WIP552_zpsh1vm5mlo.jpg

 

..the skin panels that have to go over that lot are quite distinctive so looking forward to that when the time comes :)

Once again just laughably good. :unworthy:

Stunning to observe your work Peter but it does make me feel as though I'm knitting with spaghetti by comparison.

Howdy folks & thanks for stopping by :)

 

just a little update today..

 

I needed to sort out the landing light - just like this one...

 

WIP554_zpsfiede5lf.jpg

 

..started by cutting the section from the wing..

 

WIP553_zpssqjo2ro2.jpg

 

..the lamp itself has a rounded rim so I made up a vacform tool and vacformed it from black plastic so I don't need to paint near the glass..

 

WIP556_zpsq7wchkga.jpg

 

..made a chrome dome reflector from ali and glazed it, also made up the mounting bracket from plans...

 

WIP557_zpsfsqoo02k.jpg

 

..mounted it all and spent some time trying to heat form the leading edge from PETG in boiling water - it's the blue thing at the bottom, still in it's protective wrap

 

WIP558_zpsmsbmnypj.jpg

 

..hard to photograph it mounted, but it's all in place - the whole unit had to be virtually airtight so as not to let any dust in while it was faired in - a coat of matt black means the metal won't show when I skin it..

 

WIP559_zpsr7uiz4py.jpg

 

..also installed the gun ports by adding ali tube and lining it all up allowing for the vertical offset of the barrel tubes..

 

WIP560_zps5pcy0fs0.jpg

 

..not finished, but the grunt work is done..

 

WIP561_zpsgksbkcqb.jpg

 

..having done most of the big bits on the airframe, I thought I would move into the wheel bays - I decided to cut the skin back to the mainspar to give some working room and realised the hard foam had crept in and needed cleaning out...

 

WIP562_zpsitidkkph.jpg

 

..made up some 'T' stringers from PE and strips of plastic card - I actually made another version to be folded up but it didn't work as I forgot to etch a scoreline into the top fold - these will work just fine though..

 

WIP563_zpshdoifqvo.jpg

 

..the best place to start was with the central rib, so I made up a laminate from plastic & ali and scaled the real one's layout - mine is shallower as I have brass sheet in the wheelbay roof to support the leg mounts...

 

WIP564_zps1t8ohzkc.jpg

 

..the main details & openings were transposed from the plans and added...

 

WIP565_zpsfgrpck7g.jpg

 

..and then the rib itself was detailed - I will only add what is painted Yellow Zinc Chromate (I think - anyone know the right colour?) - so I can spray the complete bay before adding all the gubbins..

 

WIP566_zpsngvnfs6a.jpg

 

..and the rib in place with the rear spar faces which are next..

 

..you can also see I had to cut a hole in the well roof as I found a big opening with loads of bobbins & pipes coming through from the engine bay..

 

WIP567_zpsxroppmja.jpg

 

WIP568_zpskuql6k47.jpg

 

..rear spar wall is next and then the stringers - after that it's all the ribs with cut-outs for the gear legs etc..

 

..I could be in here for some time...

I'm always amazed not only at your modeling abilitites but your engineering genius in figuring out what and how to do it.

I'm right with Hubert

evening folks :)

 

..I had a full day at the bench today so got lots of the groundwork done in the wheelbay...

 

..started with the face of the main spars - I took details from the drawings for where there was rivet detail..

 

WIP570_zpsyo18tdke.jpg

 

..and added flanges where there are ribs to help with placement and vertical orientation (and they are there on the real one...)

 

WIP571_zpsume7uxyq.jpg

 

..there is a central bulkhead at the front of the bay below the engine, so again I took the drawings and made a template I can use..

 

WIP569_zps5qxktqrc.jpg

 

..this isthen transferred to litho - in thiscase what actually fits in the model and a best fit made so I can use the detail but don't always have to rebuild everything..

 

I start by drilling pilot holes and then either use a burr in a dremel or a broach (best tools ever you must get some) to widen the hole to the plan diameter - a quick sand or rub with wire wool and the holes are done... for apertures I drill holes and then scribe to join the holes & break out the bit in the middle..

 

WIP572_zpscnypwtub.jpg

 

...added the spar walls and all the 'T' stringers in the roof...and also cut out two small square holes for the U/C uplocks..

 

WIP573_zpswmu2rewr.jpg

 

WIP574_zpsisbnooqo.jpg

 

..both sides..

 

WIP575_zpsyjajijm1.jpg

 

WIP576_zpsc720wv3a.jpg

 

..and in a day spent on metalworking added all the forward panels to close the bay off ready for ribs..

 

found a top tip by accident - using my UMM punch set and I used a 5mm punch in a 5.5mm hole and it flared the edge which is something I have been trying to do for ages & spent hours & lots of fails getting wrong...

 

WIP577_zps9mhpp7nt.jpg

 

WIP578_zpszaquj2og.jpg

 

..ribs next...

ribs coming along in the wheel well - each one hand made to fit the space given they are shallower than scale as the roof is lower....

Guys, don't be fooled.. i know exactly what Peter is doing here.. he has dismantled a real P-51 and is posting pictures of its component parts.

There's no way that anyone could make a model this realistic and we shouldn't be taken in by it.

still plugging away on the wheel bay...

 

wanted to make the big spar attatchement seen here (the long black thing on the left with loads of bolts in it)

 

WIP586_zpstuywxps9.jpg

 

scaled the drawing and started drilling lots of holes in a square tube of brass of the same size...(always drill any hole in anything first, before doing anything else...)

 

WIP588_zpsx4j6znis.jpg

 

..put a template each side and ground away the waste...

 

WIP587_zpsq0elrndd.jpg

 

..and added small lengths of wire & micro nuts...

 

WIP589_zps373edjak.jpg

 

..andf fitted to the spar...

 

WIP591_zpssxafhgyk.jpg

 

..also made the gear retraction unit from a bit of perspex acrylic - filed & sanded to the shape with a disc added to the front face but allowing for the slide on gear legs to come later...

 

WIP592_zpsw6npqhgi.jpg

 

..finished all the ribs...

 

WIP590_zps20hrxcco.jpg

 

..and sprayed everything with Xtracolour zinc chromate - nothing is assembled yet, just placed for the photos

 

WIP594_zpskkc0v0zy.jpg

hello again my friends

 

sometimes you get to a bit of a model and get a bit overwhelmed - that is me now in this wheel bay. The Spitfire I did was simplicity itself, a few ribs, a few pipes & done - the P51 is a complex aeroplane with many things going on and crucially differences between the C and D model (for which there are more reference pics about...)

 

..when this happens, I just try and pick a part as at some point it's got to be made, so why not now... I might not fit it to the airframe yet while I work out all the layers of stuff so things don't clash with each other, but to maintain momentum just pick something & crack on...

 

..this looked fun, so I started with it - its a condenser of some sort and in a 'C' is the opposite bay to a 'D'..

 

WIP602_zps3gwvbijb.jpg

 

..I got my lathe out & dusted it off and started turning the end caps - I only took one pic and it's rubbish so sorry about that..

 

WIP601_zpsva7jtix0.jpg

 

..I also made some of the pipe unions on the lathe from hex stock and soon had a kit of parts to make it.. the decal for the word 'CAUTION' was letter by letter stolen from a 1/24 Mosquito decal for something or other - the little one says Fuel when it shouldn't but thats our little secret ...

 

WIP603_zpshgm2yfwf.jpg

 

WIP607_zpsl3hkxy0o.jpg

 

WIP608_zpsbmerxtqs.jpg

 

..next was the inner gear door retraction jacks - again these are in a different place on a 'C' - right up front in the big hole in the roof of the bay, whereas on a 'D' they are on the rear spar face..

 

..you can see one of the pair at top left with a label hanging off it..

 

WIP605_zpsywpmdoxx.jpg

 

..lathed the piston parts and got the size / angles from drawings..

 

..the three little lugs on the fronts of the jacks had to be made and added one by one as I had no idea how to do it otherwise..

 

WIP604_zps5ickqntv.jpg

 

..and painted & decalled - this time stolen from what may have been a Sea Fury..

 

WIP606_zpsmvwd0w9z.jpg

 

..one of the most intimidating parts is a fuel selector valve assembly - the multi-pipe thing seen here on the right with all the pipe stubs..

 

WIP611_zpsicicxa6a.jpg

 

..had it been a hexagon it may have been simpler as I have some 6mm Hex brass stock, but it's not, it's a pentagon...

 

..I started by turning the centre boss on the lathe, then measured & marked out where to file flats on some ali rod and filed faces to start the core part, I also ground 'V's' into some brass tube so I could bend it at 90 degrees and solder it as you can see the unions the real one has are not curved like just bending a pipe would be so this was the only option..

 

..I made the pipe unions one by one...

 

WIP612_zpsvyvu0k5f.jpg

 

..cut the core off and drilled it toaccept the unions, I also added some airscale bezels to get the fittings on the faces...

 

WIP613_zpsbpjpebah.jpg

 

..and dry fitted - all these unions are at specific angles so I will work that out & fit them properly tomorrow..

 

..I will add heat shrink tubing for the rubber pipework later on..

 

WIP614_zpsp8twpeki.jpg

 

WIP615_zpsje2ct1ea.jpg

 

..the last little bit was adding the fuel gauge to the centre rib..

 

WIP610_zpsygqblfyx.jpg

 

..and the back of the instrument with it's wiring...

 

WIP609_zps3ccaiqeb.jpg

 

..if every day I make a part, one day it will be complete...
