    Looking great, I don't know what else to say.

    You’re welcome, also on behalf of Thierry
  3. My remark would feature the introductory words 'You're on a roll!' so let's say I agree with your assessment It's amazing how complex these structures are on the F40. I'd lie if I said this was my favourite car in looks or otherwise (think I told you before) but this topic is a must-follow for me regardless of that because of everything there is to be learned in it. I especially like the way you've been describing your own flaws / errors in execution, a gesture I consider to be something of a breeze in the world that is scale modelling where it sometimes seems like only modelling gods roam in peaceful coexistence with the fans of those modelling gods who deem themselves not worthy, thinking the gods never err and do everything right at first attempt. Miraculously, modelling magazines almost exclusively inform us of such success stories. I wonder if they are ever true. You're kind enough to show us, on the other hand, that fabulous results are to be achieved even after some trials and errors, minor as they may be. This is also one of the things I liked in Codger's (much missed) build progress description. He simply explained everything that happened... sometimes setbackish, often triumphant. Looking at the Ferrari F40's frame I consider myself very fortunate that my own project is so simple of shape and construction: just a frame, body bolted to it, engine mounted onto it, suspension, wheels and parking sensors, that's it... very basic. I hope, in your case, that one will eventually be able to see the major part of all those frames, beams, supports, struts et cetera that you're building. I personally don't believe in the adage 'at least you know it's there', although I respect those who do live by that comfort, but I DO believe in the power of amazement in case a curious jury member shines his flashlight toward the space beneath the engine, barely visible... to visually uncover a series of meticulously crafted construction subassemblies. That proves presence of commitment and if shown to those who are sensitive to it (such as but not limited to us folks, followers of your topic) it constitutes what modelling is all about: awe-inspiring sensations and inspiration for others to try doing something similar.

    Is it just me or does that look like quite a large car! It is beautiful indeed. Perhaps powerful too, at 24 litres They weren't fooling around. For the Delage I'm planning to elaborately describe the methods I'll try to use for measuring the car; perhaps that could be of any use if and when you'll get the chance to measure this car. Fortunately there are already some drawings to start from (you probably found them already when googling 'napier railton drawing', so it's a matter of getting those drawings corrected. Which is not to say it's going to be an easy task. Walkaround:
  5. Delage 15-S-8 Grand Prix (1/8)

    @NickD Thanks for those tips. I'll study them in a week when the final preparations will be made. I like the string suggestion, will definitely use that one! Laser levels... I'll try to do as much as I can with the laser I already have, these preparations being expensive as they are. Towel will be necessary indeed. 242. The thought of taking 400 dimensions max I'll just leave, unfortunately. I'll see where things will lead me. The frame is the most important basis of measurements. I sketched all bolts, structures and other particulars. The thick red dots will be measured threefold: X-axle, Y-axle and Z-axle (width, length resp. height). The red lines are minor, singular dimensions and diameters. The red lines regarding frame and springs will, in addition, be measured from the top threefold as well, in order to establish exact positions. The next drawing alone represents some 300 measurements-to-be-done. 243. I filled out the drawing on the basis of a number of prints made of photos taken at Retromobile, as well as a few video stills. Those printouts will probably prove to be useful later during the actual measuring. 244. To provide an example of what I plan to measure... the orange dot. 245. It's this screw.246. Y-measurement: the laser measuring device is situated in front of the car on a set location, pointed parallel to the center line of the car. The laser is reflected at the screw. 247. Z-measurement: the device is pointed toward the floor, from the screw. 248. The X-measurement: Supports / reflectors are positioned on both sides of the frame, leaning to the frame. That way the distance between both supports can be recorded. Seen from the frame, most of the other dimensions can be established. More info on the preparations in due time. Total building time: 47h. Total measurements study: 54h.

    Ron, May I urge you to reconsider selling the kit right away... stories are numerous of modellers who sold their stash / equipment, only to much regret that decision later. For the 250 pounds I'd keep the kit for another half year or so, to decide then. Think of all the time you spent on the kit and the amount you're now asking for it.... or perhaps sell it to a friend who will keep it for you, in case you'll ever want to resume work on it. Hope you'll consider this. If this is not an option, regarding the scratchbuilt nuts, you might consider contacting forum member Mustang who was interested in making his own. Perhaps you could save him some work by selling them to him. Brgds Roy

    I'll try not to forget that! Put it in my things-to-do list. Hopefully I'll have time to see the rest of the museum. I think I'll be busy most of the day on the measurements. I'd love to have a look at the other cars as well... Your hopes are set a little high But I'm quite sure that the dimensions will be much more precise than I have now. "Dear Mr Agnelli, Coming back to the matter of the priceless car you once destroyed, (...)" It is and always will be a shame. I really look forward to start working on the model as well. But all this preparation has its fun too, I must admit. If my work would reach Mr Wingrove's shadows I'd be quite happy. I'm not exactly sure what you mean by 'faded on top of it'. The square swirls are doable by means of the recently acquired tool. If you want I can send you a specimen to test with (I have 10 and I can always get more relatively easily); it's ideally used on a milling machine. You could try using it in a collet. If you're interested just send me your address per PM. Measuring a Grand Prix car241. Measuring a car, how hard can it be... the answer: more difficult than it would seem at first glance. Although I've been very busy with my 'regular job / work', which will not change much the next two weeks, it would have been imprudent to not prepare (the preparation of) the measuring work. In planning I'll follow the method outlined by Gerald Wingrove in his unrivalled book 'The Complete Car Modeller 1', pages 11 to 22. The last couple of years techniques and tools have improved so in addition to the techniques described by Mr Wingrove I'll use a laser measuring device for dimensions larger than 15 centimeters. I'll use Jim Ison's drawings as a 'fill out basis' because although those drawings aren't completely accurate number-wise, they do provide a nice basis for an overview of points and dimensions to be measured. It doesn't matter much that the dimensions according to Mr Ison are not correct, because for this purpose it's only important that the general shape is correct. It's like using a template. I will follow the three-step-plan by Mr Wingrove, described on page 19 of his book: 1) Taking a number of measurements to point out the external shapes of the car. This will be done in Florida. 2) Plotting the basic shapes and 'coordinates' on paper and, on the basis of photos, filling out the missing and smaller details. This can be done at home, but extra photos will have to be taken. 3) Each time a part will be modelled, that part will first have to be drawn in a separate drawing, on the basis of the main drawing described under 2. Preparations are currently focused on 1), but each time I think of extra photos that could come handy or are required I'll also note that (for the benefit of 2. and 3). These are the measuring tools I'll use: Most tools will speak for themselves. The laser measurer is Bosch: affordable, very accurate and very basic function-wise. I won't need anything more for this single project. Graduated ark I'll use to... measure angles; measuring tape for measuring curves. The electronic caliper isn't highest quality but I won't take my Mahr to the USA.. that's too risky. The caliper can't be carried in hand luggage because it's sharp; and we all know how harsh airport groundhandling sometimes treats suitcases... Every 'coordinate' will have a twofold-measurement, at the least: height and either length or width. I'll start measuring length-wise, then front- and rear measurements, next the top dimensions and finally interior, engine and wheels. As Mr Wingrove wrote, first I'll need to establish some 'anchor' or 'key' points. Starting on the wheelbase, that's approximately 2.500mm. and I'll call, as Mr Wingrove did, 'A'. Next I'll measure how many millimeters, horizontally and perpendicular to the car centerline, the distance between front wheel center and front spring shackles is. All spring connecting points are measured from the respective wheels (two front, two rear), called 'B1', 'B2', 'B3' and 'B4'. I'll check if the combination of A, B1 and B4 equals the distance between the outer connection points. The height of these points will be called 'C1', 'C2', 'C3' and 'C4'. Now the parts connected to, and subassemblies near, the chassis can be measured from one of the B-points, always perpendicularly to the car. Chassis curvatures are therefore not taken into account. I'll often do checks. Subassemblies, nuts, bolts will also be measured as much as I can. After the chassis and its fittings will have been capped lengthwise, the rest of the body can be measured. For that I'll need higher points, such as the front firewall lining and the end of the radiator house. The heights of these points will be measured as well. Next the width (top, front and rear views) will be measured, based on track gauge, grille ends, distance between springs et cetera. Many measurements of the chassis shape and body width will need to be taken. These 'threedimensional points' will need to be connected to previously performed measurements as well as the floor. To fetch the absolute lengths (for example from wheel center to one of the ends of the springs, say B2) I designed a little system that I might use, perhaps slightly amended. Based on this drawing: Explanation: the laser will be put inside a block of wood (yet to be carved). Only the height of the laser beam can be amended. The wooden block will be positioned perpendicularly to the car thanks to the use of an L-profile or the like, put parallel to the car. The laser beam is aimed at the center of the wheel (step 1). Idem the second (identical) wooden block, pointing at one end of the springs. When both blocks are rightly positioned, the distance between their centers can be measured using the laser beam. That will be the absolute length called 'B2'. I'm not sure how all dimensions will have to be established but I'll continue thinking long and hard about that. In total, for step 1 I'll have to take approximately 300 to 400 dimensions, inclusive of engine, wheels and interior. It's much easier to make a model based on a blueprint than vice versa, but because there's no blueprint of this car and because I'd like to have it as accurately as I can, a little bit extra trouble has to be undertaken. The eventual, very elaborate, step plan will be shared in this topic; as mentioned before I won't share the dimensions; but of course I'll describe the modelling based on them in detail as usual. Total build time: 47h. Total measurements study: 51h.
  8. Pocher Ducati 1/4 - two nuts

    I received a request to make another one of these. Unfortunately time doesn't permit that, I'd love to start the Delage measuring preparations... least I can do though is make better photos of the drawings, as these may be used for 3D printing or so. The third one I think I didn't upload before, I think it was the first sketch / step plan. If anyone has a question about writings / numbers etc., just let me know and I'll try to decipher.

    As regards the lighting holes, of course nobody knows for sure as the car was unfortunately scrapped in 1928. Some thoughts on the subject though: * It's true that the Delage 15-S-8 had very similar holes as depicted by Harvey, although I have no idea where you found that (or if you simply guessed it right). I don't recall having seen any photo online on which that structure is shown. This is what you see in the car: These are my own photos. There's another photo taken during restoration of a Delage showing that behind the seat back rest there are at least five round holes just like the big ones in Harvey's own version. Unfortunately I'm not allowed to share that photo. * Everywhere on the Delage evidence can be found of weight reduction. Already 90 years ago they really took this matter very seriously. On the other hand, getting these cars as close as possible to the minimum weight of 650 kilograms for these 1,5 litre cars, as announced in 1926, generally didn't work out as well as was generally expected. I'll quote from pages 51-52 of 'The Grand Prix Car' by Laurence Pomeroy, 1st edition 1949: [Nearing the year 1927...] Everyone was agreed that the existing 2-litre cars were too lightly constructed and the prospect of a reduction in weight, coupled with a maintenance of speed due to enhanced engine efficiency, led to predictions of dire disaster. Indeed, responsible persons claimed that less than half a dozen drivers could take full advantage of the existing 2-litre cars and they considered that new, and lighter, 1,5-litre models would be even more difficult to handle. These criticisms were based on the assumption that designers would do all in their power to reach the minimum weight figure. In point of fact they did no such thing, practically all the cars scaling between 2 and 3 cwts. over the minimum which, in any event, was raised to 13.76 cwt. in 1927. If I had to guess, I'd think there's a more than reasonable chance that Fiat, trying to minimise the weight of their car (and, at the start of the season not knowing whether their competitors had been able to build lighter cars, and therefore perhaps feeling a bit anxious), did exactly the same thing as Delage did on their own car: remove as much metal (=weight) as they deemed opportune strength-wise vs. weight-wise. But as said, we'll never know for sure now and I'd say that in themselves Hannes' thoughts are valid too. As there's no certainty I guess it would be fair to say each depiction of the car should be considered equally acceptable.

  12. Delage 15-S-8 Grand Prix (1/8)

    Good news! Rev's Institute has welcomed me to visit the museum and take all dimensions I need to make the drawings. I'll fly over on the 9th and will get back on the 16th of February, so after a week. Obviously I'll use the opportunity to explore Miami, the Everglades and the Florida Keys, as I have never been to this part of Florida before. I'll just consider it a holiday! When at Naples I'll do quite a few measurements on the car, something I'll try to prepare as well as I can. Also I'll make a list of parts / points of view that I don't have good photo references of. After having studied my photo map last week it seems I have more stuff than I had thought but still, not everything I'd like to have. Also, not everything was photographed from the right height. I have decided to not share the dimensions or the newly made drawings in this thread, as I would hate it if Heller, Ebbro or a small kit producer would simply see this thread and use the dimensions for a new kit, not remunerating me for my energy and expenses (as a hobbyist!) of fetching those dimensions or creating those drawings. Rev's Institute has agreed to act as custodian of the dimensions and the drawings based thereupon. Of course I won't cease to share an abundance of build, method and technique pictures in this thread. I guess 99,99% of all visitors (those who aren't interested in scratchbuilding this particular car) wouldn't care in the least if the dimensions or drawings were made public, but it seemed nice to explain anyway. More news in due time.
  13. Who needs those! Looks good Thierry, you're on the right track if you ask me.
  14. Delage 15-S-8 Grand Prix (1/8)

    @Hannes I had not heard of that book and ordered it today, thanks for the recommendation. When I was at it I also ordered 'The complete history of Grand Prix motor racing' by Adriano Cimarosti, a book that had been on my wish list. World of Books had one of each, seemed like a nice opportunity. 236. Meanwhile Rev's Institute informed me that there had been an error in measuring the wheelbase; it's 2,500mm. (98,5") after all. This has solved one issue regarding the structure / space between steering wheel and rear of bonnets. The new version of this drawing starts to look a lot like the real car. Here a comparison between Mr Ison's drawing (bottom), the newly amended drawing (center) as well as an overlay drawing of these two (top). 237. There's more good news. I remembered that some photos of the inner views of the car had been published, particularly this one:(Copyright Auto Restorations Ltd. New Zealand, educational / referential purposes only, picture will be deleted upon first request)238. I measured the diameter of two adjacent cylinders, calculated their average and compared that number with the space between those cylinders. This proved that the cylinders in my drawing were spaced too broadly. I therefore compressed the cylinders (no pun intended, honestly), using probable dimensions between cylinders 4 and 5 and behind 8. Fortunately the new assembly fits the new drawing rather well (yes! #1). En plus, the bore appears to match those numbers as mentioned in literature, being 55,8mm. (yes! #2). This is what the intermediary result looks like: Yes I'll admit I played with the pistons' heights a bit... 239. Meanwhile I asked Rev's Institute for permission to measure the car electronically, because that would be more precise than measurements by hand and sight; this would moreover be an opportunity to fetch more dimensions than planned originally. Lastly I'd be able to take some more photographs that I had forgotten to take while at Retromobile. There could be multiple reasons to refuse such request; this being a unique and invaluable car... I can imagine the owner would prefer to have this car have as little contact as possible with eager research fingers. On the other hand, no blueprint of this car has survived WW2 so I can imagine Rev's will consider it opportune to have a drawing that's as accurate as possible (and considerably more accurate than any of the existing drawings, to say the least). If I'll be granted permission I'll probably fly there this February. Next I'll make the drawings and building can finally start. The reason of all this trouble to get correct information is that I'll only be able to motivate myself to finish a job of thousands of hours if the basis is correct. 240. I also found this beautiful impressive picture of the engine in full glory (chassis #5). The compressor can here be see very well, with nothing to block view. (Copyright Supercars.net, educational / referential purposes only, picture will be deleted upon first request)At first glance it looks like it's an enormous engine, but that really is just an illusion. The total length between front of compressor till rear of block is only, approximately, 106cm. (41,7""). It's just a small 1,5 litre block after all. Hopefully some more news on my request to Rev's soon. Total build time: 47h. Total measurements study: 48h.
  15. Delage 15-S-8 Grand Prix (1/8)

    @NickD Ill update more in detail later. Some preliminary highlights: - Re-measurement proved it’s 2500mm. after all. Other dimensions are okay. - New drawing looks very much near the truth. - Engine drawing redone, fits beautifully now. - Have asked for permission to fly over to Florida to measure the car electronically for greater accuracy and more dimensions, as drawing of Mr Ison cannot be used. Yes I’m crazy. Will get an answer on this request in a few weeks. More info, including very promising new drawing, to follow.
