  1. superb job Nige it really flicks my switch when I see thorough research and fuss free tips on how to improve a kit - no kit is perfect and I think HK have done an astonishing job in getting this out to market - for that they should be thanked & congratulated and I know Neil would love to see how people go the extra mile to take his canvas and make it their own... nice job Peter
  2. well hello folks can't believe a month has passed since I last posted an update... I have not been idle though - I have done a lot of 3D modelling for the tailwheel, main wheels (for which I am getting help!) and the spinner (of which more later..), in between I have also released an airscale instrument panel set for the Hobbyboss 1/32 B24 Liberator and also worked with Airfix to master this airscale cockpit set for the new and mind blowing Airfix 1/24 F6F Hellcat - the decals for all the instruments & placards are in production, but the PE is done.. ..as for the P51, when I had the Hellcat PE test shot done, I also added a load of extra P51 stuff to the fret so I make the most of one-shot production, Part of that was the stainless steel side panels that surround the exhaust ports, and I also made a fold up box structure that is the structure that surrrounds and supports the exhausts themselves.. ..Also seen here are the 3D printed exhausts from Model Monkey - huge shout out for these as they are exceptional quality and amazingly are hollow so are ultra realistic.. ..these were folded and the details added before the boxes were added to the outer panels - the exhausts are not yet fitted so they can be painted & added at the end.. ..and so onto the spinner - this is one of those things that has sat in the back of my mind as a niggle since I started this build - it is unfortunately unpainted on the real aircraft so had to be made in metal - a bit like skinning a tennis ball in sheet aluminium - very tricky.. ..I actually bought the HpH 1/18 Merlin engine model hoping to cheat and get a good basis for the prop & spinner from that, but it is very crude - the spinner is a solid with four peg holes in it to take the blades - there is no reference to the cutouts on the real thing, so that was a 70 euro write off (though I think I can use the blades so may not be dead money...) I restarted my Rhino 3D programme trial and got to work modelling the Spinner... ..when I went to get it printed at Shapeways, I noticed you could choose polished Aluminium so I thought well that would be brilliant as it would save lots of messing around with skinning as I could just polish the part - so at great expense (150 euros) I ordered it with the hub done in plastic.. ..two disappointments... one - it's not polished at all, it is more like a carbide burr in texture, and two, somehow I got the hole cutouts wrong as two were in the right pitch for the blades and two were in the opposite pitch.. ..that said - it is aluminium, and after filing & polishing is just like a cast part - don't know how they do it, but it's bloody clever.. ..as the cutouts were wrong, I knew I had to skin it, so I made a tape mask and started with the lower section... ..with this skin added, I taped it to the top part to mark another tape template with where the cut-out holes were on the next bit of skinning (there are 3 - bottom, lower of the top cone, and the tip) ..this skin needed rows of 3 rivets adding so I made up a jig I could do this accurately with.. ..I was hoping after adding this I could get away with the spinner tip being the base aluminium part, but there is a lip that can just be seen.. ..in doing the tip, I nearly gave up as turning one sheet into a fully compound curve sheath without a visible seam proved very difficult - I don't have any in progress pics, but at this point the bulk of the shaping has been done and the skin runs up over the lower part - I was hoping I could just sand & file this away for a nice close fit (I should have started with the tip & made the lower panel fit it, not the other way around..) ..once it was all sanded away, I was really happy with the result.. ..the prop hub was painted and added to the base.. ..and it is a perfect fit.. ..it feels great having got that done - everything else is easy by comparison I also have the right sheet aluminium that Brian (Out2gtcha) kindly shipped from the US on my behalf so can now start skinning the airframe.. ..a milestone I think, and hopefully the start of more regular updates.. TTFN Peter
  3. Love it I am not a huge jet guy, but I know this is one of the Holy Grail's of modelling and I can recognise & enjoy seeing real modelling skill on display.. Excellent job Cees Peter
  4. crikey thanks guys - I am very grateful for your kind compliments and it is you guys I consider my primary judges who I must do my best to please not much of an update, but it is still a fair few hours work.. I added the main pipes that go in the front of the weel bay roof - these are aluminium tube with insulating tape for the black bits and foil tape for the clamps.. I also made up the uplocks which are tiny parts made from scaled plans and also the gear door sequencing assemblies that are another set of tiny parts with connecting rods.. they are the bits in and around the square holes in the bay roof.. ..and the other side.. ..it may be difficult to grasp the size of these parts so here it is with a 5 amp fuse.. ..starting to look busy.. electrical wiring next, then I think most of what I wanted to do here is done and I can close it all up and protect it and start work on the fuselage structure around the back of the canopy which is entirely absent at the moment... TTFN Peter
  5. hi folks so, I am really glad this week is over - just look at all this piping... I got some 0/6 and 0.8 solder from Amazon which was all I could think would be silver, but flexible enough to be able to bend.. the inherent problem in this is that is also easy to bend by accident, so I would roll it flat using a sheet of balsa and a book (so as not to scar it), slide a brass tube along it to where I wanted to bend it and then bend as needed. This works but for stringing it through holes, through or behind fittings it was an extremely tiring, demanding and frustrating job.. one I could really only do for 30 mins (or a pipe) at a time.. I made loads of fittings and parts the pipes connect to and while I don't have in progress pics, now I have done the bulk of it, and added the door retraction jacks, I took a bunch of photos of where it is at... ..and in detail.. ..so thats it - my eyes hurt onto the uplocks & all the big pipes in the big hole at the front next... TTFN Peter
  6. haha you guys make me laugh - I want to learn how to knit! had a bit of time this weekend, so lets press on... ..first up some landing gear torque assembly fittings - seen here, it's the green bracket & bellcranks and a torque tube.. these seem to sit the deepest under the fuel selector so had to be done next.. ..first I made the housings from plastic card... ..then made up all the belcranks and any bits that go in either bay - primed white as I have run out of mr surfacer... .. ..then all these were painted.. ..and assembled, including tiny banjo fittings where small rods come off the cranks to various bits... ..and added to the airframe - the lower roof height in the model is making placing & spacing some of this stuff challenging... ..next this bit - the fuel shut-off valve - it's quite a distinctive and complicated little assembly... ..no build pics for this bit, but here it is completed... ..also added the hydraulic accumulator.... and then spent many hours plumbing the fuel selector valve - there is still one pipe to go between it and the fuel shut off valve, but there are some gubbins I need to add before doing that... ..still lots of bits to do, but feel like its a bit of progress to get that done.. TTFN Peter
  7. Crikey - that is superb stunning job, there are so many things I like about it, I don't know where to start.. Peter
  8. 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'.. ..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.. ..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 ... ..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.. ..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.. ..and painted & decalled - this time stolen from what may have been a Sea Fury.. ..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.. ..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... ..cut the core off and drilled it toaccept the unions, I also added some airscale bezels to get the fittings on the faces... ..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.. ..the last little bit was adding the fuel gauge to the centre rib.. ..and the back of the instrument with it's wiring... ..if every day I make a part, one day it will be complete... TTFN Peter
  9. evening folks 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) 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...) ..put a template each side and ground away the waste... ..and added small lengths of wire & micro nuts... ..andf fitted to the spar... ..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... ..finished all the ribs... ..and sprayed everything with Xtracolour zinc chromate - nothing is assembled yet, just placed for the photos ..thats it for now - back soon TTFN Peter
  10. thanks chaps 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.... ..just the last pair to go... TTFN Peter
  11. I like rockets - no canopies Superb job as usual Jeroen, looking forwardto following this one Peter
  12. 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.. ..and added flanges where there are ribs to help with placement and vertical orientation (and they are there on the real one...) ..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.. ..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.. ...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.. ..both sides.. ..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... ..ribs next... TTFN Peter
  13. Howdy folks & thanks for stopping by just a little update today.. I needed to sort out the landing light - just like this one... ..started by cutting the section from the wing.. ..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.. ..made a chrome dome reflector from ali and glazed it, also made up the mounting bracket from plans... ..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 ..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.. ..also installed the gun ports by adding ali tube and lining it all up allowing for the vertical offset of the barrel tubes.. ..not finished, but the grunt work is done.. ..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... ..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.. ..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... ..the main details & openings were transposed from the plans and added... ..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.. ..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.. ..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... TTFN Peter
  14. So do I - I think that is next on my bench in a year or two, just like that one Stunning build as usual John Peter
  15. 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.. ..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... ..then from many scaled plan parts I assembled the main structure from litho, with brass strengthening where the wheel leg will mount... ..added some details and skinned the sides of it so it can drop in as a complete pod... ..this was then added and CA'd into position ready for the fuselage section to be added back & filling.. ..and after cleaning up, the basics are in there I can come back to later.. ..I also added the airscoop and got the shapes in this area where I was happy with them.. ..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.. ..the moulded fillet is a bit ugly and will need quite a bit of work.. ..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... ..then lots of filling & shaping and trying hard to work around and not damage the skinned part of the airscoop... ..and finally after a shot of primer to see whats what, the basics seem to be coming together... ..the skin panels that have to go over that lot are quite distinctive so looking forward to that when the time comes TTFN Peter
