    Caterham R500 Race car - Custom Build - 1/12

    Right - almost there with these..so some more details: Kit comes with a large steering wheel - JPE version comes with a MOMO but not the right one, and I need 2 anyway - so back to Solidworks and the 3D printer! ..end result: I also made some numberplate lights for the rear of both cars... One of the last big jobs - seat belts. The kit comes with a set of harnesses, with some sticky-backed, satin finish material, printed - but red. And not great detail - so I have to make my own. Standard practice is to use ribbon - I did play around with using 'lead' sheet - as found round the top of fancy fizzy wine bottles - used by the scale WWII plane makers - it is great because you can shape it really easily - but better on smaller scales I think - a bit thin for my purposes.... So I bought some black ribbon - 4, 5 and 6mm covered it. I needed lots of buckles and clips, so I redrew them in 3D and printed a variety - advantage of this printing is that if you fill the bed completely, it takes no longer to process - so may as well make some spairs/some to lose/some to try different finishes with... Testing... I wanted this 'crease' at the top buckle... I din't want them all the same in all 4 seats, so I varied which buckles were connected and which would be 'loose'. Fiddly little buggers to make though - folded the ribbon and glued with super-glue. Trying different glues for the paper printed 'Caterham' logos... ...and completed: Applied logo's to the seats - each car was different - particularly important for the customer! I think one of the cars was perhaps the first with a particular branding (Tillet or Caterham) Exhausts next - I have been playing with the best way to draw/print these - I had some sagging in some prints when done on their side: (Note, these black test pieces were printed at a lower resolution to speed up the printing time!) - I tried 2 halves, but just adding work to actually join and fill/smooth - so the vertically printed ones work best - print takes a LOT longer because of the much larger number of 0.01mm layers! - not figuring out the pipe run - again a bit of a bugger to do! Of course each car has a different can!! Making the exhaust system in separate parts lets me play with the angles more easily - so end pipe, can, long bent piece into collector, and then the 4 pipes that disappear into the side skin - engine-bay side pipes were done years ago as part of the engine. Once this is done, the last 'big' job is the clear 'windscreen' wind deflectors...

    These close up pictures show up all sorts of details/marks etc that you can't see with the naked eye!!

    Wheels needed some more details before fitting, so I added some tyre valves and the wheel nuts, and then the 3D printer was used to make a mask for spraying the 'AVON' graphic on the tyres, which is a detail which will look great on the race car. Luckily it worked first time...:) I modeled the tyre profile on the mask, as the spray would need to go around the profile of the tyres... tiny bit of touching-up will be required on the wheel paint....

    Hard not to go back to parts that I fitted/assembled 15 years ago and replace/improve! I changed these 'large' screws which held the pedal box cover on with 'rivets'... I need to be careful with this, otherwise I might never finish... 3D printer is getting more use - first with the shift-light module... And then making 2 dry sump pans - these can't be seen once fitted, as the car is so low - but they need to be there on the bottom of my custom 'K-series' engine...so not 'perfect' modeling, but good enough. Having made the '7' grill with the 3D printer, I now added the mesh 'panel' that sits behind the grill, in front of the radiator. This has worked out really nicely, imo! I sprayed a plastic mesh and glued in place, to be trimmed later... Of course it isn't all plain sailing. The paint finish on the rear wings had develped tiny cracks - it may have been the clear coat I used - but it meant I had to sand back and re-do. I masked the (home made) decal on the wings and sanded/resprayed. It only required a polish really. But the masking tape pulled the decal off...grrrr. I thought I had clear coated over the decal, but it didn't seem to hold it... So I had to remove, re-sand and re-spray without the decal - I did not have any more of these, which I had printed in NYC. No big deal, as only one time-period of the car had these particular race stickers on. Starting to assemble more sub-assemblies/parts now...

    Right - back on it after a trip to France and marshaling at the British F1 GP! I tried a bit of clear resin to make the rear fog and reverse lights - I'd made the casing already, so made the 'lens' to fit inside. I thought I'd try a few details inside in the lens to see if it showed when painted (with clear red) - it actually worked quite well! I used a bit of silver paint inside the lens to help, especially with the reverse light. I'll add some screw details later... I had a back-up plan using some clear red reflectors cut up, but the printed clear worked well... ...although I did have some weird artifacting with some of the prints - I think what happened was that the first few layers stuck to the FEP film, not the plate - then it stuck, and then i was getting some refraction of the UVA light through the clear resin - no idea, but I managed to get a few pieces that worked for what I needed. I needed to find a way to fit my wheels - the bolt holes did not quite line up - I think the file was scaled slightly over the years, but I wanted something stronger anyway... Incidentally, the Tamiya kit is so well made that it even has the alternative suspension mounts that the 'real' car has - in this model the trailing arm (link arm?) is fitted in 'comfort' mode - the lower boss is for better handling. It is all to do with 'rear steer' on the de-dion tube, and this kit actually can be used to demonstrate the difference and why the 2 positions work - I'll make a video next time I make one... So I drew up some 'spacers' (I wanted a slightly wider track) which included the rear bub bolt and the front bearing grease cap. These would mount on the existing wheel bolts, and fit snuggly into my new alloys. I used my trusty metallic pens to colour these - quick and effective! Needed to finish one of the cages... ...and some more decals.

    Finished the wheels (or at least the main parts - need to add the air valves etc!) Printing the tyres was a pain - teied different angles etc, sometimes they would 'sag' as they printed due to the number of supports - still learning all that! Had a few flats! But once done, and cleaned off - I primed and sprayed with Tamiya Rubber Black (or tyre black - can't remember) - I am going to print a mask to spray 'AVON' on the tyres. I ended up using Alclad Chrome on the rims - but not to full 'shine' effect - just enough to glint a little bit. I did try the Spaz chrome you can see, but wasn't impressed - far more to do with prep. and not fiddling with the airbrush - alclad gave me a 'hint' of chrome over the top of the other.. . Nothing fixed or attached yet... Lots of small bits next - mirrors, fog/reverse lights mainly... Getting pretty close to assembling these parts to the cars and....finishing!!

    On a mission now, so I also drew up some other parts - the tiny ones like fog lights, rear view race mirrors etc - none of which are correct in the kit for what I need. I also drew up the '7' grill, which printed amazingly - years ago I had tried to resin cast the original wire one that came in one of the Tamiya kits (The VX powered JPE) as I needed more than one, but it was impossible - not now! I had to make another cooling fan for the radiator of the blue car - the yellow one consisted of part of a camera film case, carefully bent wire, carved fan blades etc etc - huge amount of labour. I drew up this one, made the fan separately so I could paint more easily,. I'm currently trying to get the wheel/tyre sizes spot on so I can manufacture those, and am about to start finishing and painting all those parts to assemble...

    Next job was the tillet seats - carbon fibre race seats which are only about 4mm thick in 1/1, and are very curvy. Now I had the tool to print them, I still had to create the 3D file - youtube solidworks tutorials to the rescure: Not perfect in terms of 3D drawing, but good enough for my use! UV curing: Had to get the scale right, and played around trying to get the shoulder 'bulge' correct - this had to fit in the model... Once I was happy with the size and shape I primed and sprayed black - although the seat was kevlar, so it would be covered with decal and also some fine flocked sheet to represent the fabric on the real thing... Fun shape to try and cover! Once I had added the kevlar, I thought it looked a bit too yellow, so I sprayed a few layers of Tamiya 'smoke' to darken it a little...much better. Quick coat of satin clear to seal it all up. Then the self-adhesive flocking material - bugger to get the shape right for the side pieces... Most of the rear and lower sides of the seat would not be seen, so I saved materials...still have a few bits to patch up, but overall - done! These seats were the biggest issue to figure out - its only taken 15 years lol

    OK - BACK TO 2019 - another 4 years have passed since I did a bit of work in NYC on the decals and dashboards....but then I had the brick wall of how to make some bits... In the mean time I had taken up model making again in the States. New skills and techniques mean that I just know I am not going to be able to resist going back and adding more detail to these kits - particularly when it comes to paint finished and washes/panel wash etc. But the biggest issue was the damn seats. I've kept up to date with the 'home' 3D printer market, but the FDM printers (the ones that squeeze molten plastic out of a tube - think toothpaste - and build up layers) simply don't have the resolution required. Cheap though - you can pick up a descent kit for £150 - good enough for learning and 'rough' stuff - although actually they are still pretty good now! - and clean...as soon as you start to use resin you have mess, smell, clear-up everytime etc etc.. Resin printers, that use a laser to 'set' UV sensitive resin in very thin layers, are a different level of cost! You are looking at £2-3k for a good, small model.... ....until now! There are now a handful of small printers available for less than £350. These use a UV emitting LCD screen to 'set' each layer - the resolution (thickness of the layers!) is way higher than any FDM printer - in fact you can even see the pixels of the 2K LCD screen being printed if you really zoom in. So last week I invested in an Anycubic Photon - a very popular Chinese printer you can get from Amazon. It produces stunning results.... It has a small print area, but for the size of parts I want to make, it is fine. DO NOT READ AHEAD IF YOU DON'T WANT TO BE TEMPTED - THE RESULTS YOU CAN GET FROM THIS PRINTER ARE AMAZING! Of course you have to draw the 3D cad files to print - I have access to Solidworks, which I have used in work - but I am not an expert user by any means - I have been drawing boxes and shelves in NYC - so the learning curve to draw a complex shape like a Tillet seat is large! I thought I'd start with some wheels and tyres - these models have ACB 10 tyres, which have to be the simplest tread to try and draw up as well - result!! So - I worked through some tutorials, and... So on to the first print - the printer comes with some resin to try - in this case, translucent green...out to Dads workshop.... BOOM! I was amazed at the results... Moved on to some grey resin... ...as I had the file for the central cast hub, I am able to reproduce those as well - lucky as I can't find the plastic sheet with 8 hubs machined onto it from 2003! So this is a 3 piece wheel: I have to play around with sizes to allow for paint clearance etc - but it works brilliantly. You can get different types of resin - so I have got some flexible resin to try and make 'real' tyres - I'll have to reduce the wall thickness right down, and make sure I can use pigment on the resin to make it black - as the flex resin is clear - but that is to come. I'l probably use the grey hard resin and spray for now... More updates tomorrow - I'm staying up waaaay too late every night working on this - but it is good to get the modelling MOJO back after 18 mths....

    Hi Robin - cheers mate - appreciate it - finally got to the next stage so about to start updating again - can I ask a big favour (that is not important in any way) - could you possibly edit your post above to not 'quote' the thread - I keep trying to edit your post and it doubles the page length for scrolling lol - hope you don't mind!! cheer
  13. De Havilland Mosquito FB Mk.VI This particular version is modeled on one that took part in Operation Jericho, RNZAF, No 487 Squadron Finally - that took a while! My first aircraft kit (although I started and finished a Spitfire for a mate in between) and it is a cracker - I know it is expensive, but cannot fault this Tamiya kit. Although I used some Eduard detail kits (engines, guns etc) you certainly do not need these to make the kit amazing. I'm learning the weathering thing, and I know this is a little 'dirty' - but I thoroughly enjoyed it and learning what I did. ...sorry, I find it hard to edit the number of photos I want to do some more pics with a bit of photoshop play, backgrounds etc.... And finally - I posted the montage below on FB.... ...within minutes a friend sent me this. She made my day and it makes me smile each time I see it....

    Gonna start a finished thread, but here is a preview!

    Tamiya 1/32nd De Havilland Mosquito

    I added a bit of shadow to the canopy... ...although I seem to have not taken any pictures of that! I bought one of those plywood frames to hold the plane while I work on it - a bit flimsy, but I recommend it - saves damage from fingers etc, especially when working on the underside. At this point I was touching up chips etc where paint had fallen off some PE bits... It can be adjusted for different sized models... Props were next - I had left them as I did not want to damage them. Although I painted and 'weathered' the hubs, they won't be seen (of course!) I did add some 'chips' to the leading edges of the blades, and add some 'streaks' - but kept it quite subtle. Next it was the exhausts. I used some of that 'buffing' Humbrol paint which I had from years ago, oils and some rust 'powder' - no real planned combination, but it came out ok! ...again, some of the shine was taken back later. Almost forgot the mesh guards that are on the air intakes! I used graphite pencils and some wash to add depth to the engine that would be on display...this is a 'finished' shot... I had to tweak the multi-part canopy a bit to help it fit - the internal frame was a little high and was stopping the clear bit from fitting easily, so I had pried it off the model, and shaved a tiny bit off the frame so it sat a fraction lower - then I glued the canopy itself on with white glue. And that was pretty much it! I took lots of 'finished' photos (which I'll post in the 'finished' section!) and only after taking these did I realize I had missed off one part - the windscreen wiper!! (now added) Now I just have to figure out how to display/mount it. I like the idea of keeping it clean, but it needs something, so maybe a grassy base....then what - I don't know! No where to display, and the joy was in the building for me, so maybe sell it? But then again I like the idea of displaying it with the 1/32nd Lancaster (HUGE) and a 1/32nd Spitfire and Hurricane! Finished photos next...
