Hi everyone ,it's been quite some time since i posted anything new, so i decide to make a small tutorial,of how i make my scratchbuild aircraft,this tutorial is for my new fb-22, i hope you like it.

first you have to draw the aircraft that you want to build

this are the tools i use to cut the polystyrene

to help see the lines were to cut ,use a pen to mark the polystyrene

this is the fuselage after being sanded

in this picture you can see were the airintakes and exhaust , are located

now the fuselage is ready for cutting the wings,this is the type of plastic i use
(https://www.whatifmodellers.com/proxy.php?request=http%3A%2F%2Fi868.photobucket.com%2Falbums%2Fab242%2FPEDROSPE%2F100_1369.jpg&hash=b38329cf14a902450bbab2674961d9ebb2f1af23)
the wings are already glued and the cockpit is also ready
(https://www.whatifmodellers.com/proxy.php?request=http%3A%2F%2Fi868.photobucket.com%2Falbums%2Fab242%2FPEDROSPE%2F100_1370.jpg&hash=8d3488e048bee0b1dd21c9d87add5d4f8198b8bc)

since you can not mark the polystyrene, i use self adhesive paper or plastic sheets, to mark the panels of the aircraft
this is how the aircraft looks after everything is done

as you can see it's not very difficult,but it takes a while to get use to work with the polystyrene and all this materials are very easy to find, feel free to ask me any questions.

Pedro
That's just like those solid balsa kits I built as a kid, 50+ years ago! :cheers: :cheers:
bobbo
looking really good.
One question, how long does the physical build take?
That is just pure genius !!
OK... how do you manage the cockpit well and other hollow areas?
:unsure:
Wow!!
That might work on my future car builds, thanks :thumbsup:
Thanks for taking the time to prepare this tutorial. It helps a lot.
The "polystyrene" you use for the fuselage seems like some sort of foam, resembling styrofoam. Does it have a brand name?
That's very nice, interesting tutorial as well. Many thanks :thumbsup:
How do you paint the polystyrene foam? Can you just apply paint on the foam, or do you need to apply a layer of putty first?
royabulgaf: you'll need to look for expanded polystyrene foam (EPS) or extruded polystyrene foam (XPS).
I think this material is XPS, it's more uniform and can be sanded to a smoother surface than EPS. EPS is commonly used as packaging material (e.g. packing peanuts).
Styrofoam is a brand name, they produce XPS.
HI everyone thanks a lot for all your kind comments, i ´m sorry that this tutorial is not as completed as i wished for ,but i don't have much time for making it better,sorry about that, one very important thing that i forget to say,is that you cannot use any SOLVENT BASED GLUES to glue the polystyrene, because that will destroy the polystyrene, you can use non solvent glues from uhu that can also be use , to glue plastic parts (like wings ,airintakes,canards etc...)to the polystyrene, another very important thing about painting, do NOT USE ANY SINTETIC PAINTS,to paint the polystyrene,because that will destroy it ,use acrylic paints,now to answer your questions;DARTHSPUD-it takes me about a week to build an aircraft,but it depends on the time you spend on it, i usually dedicate about 3 hours a day,the fuselage is the part that takes more time,mostly the sanding process.
ROYABULGUF-well the polystyrene that i use can be bought on supermarks that sell construction materials,here in Portugal i can find it on AKI OR MAXMAT, the polystyrene can be roofmate or floormate, the roofmate is better, because it is easier to sand ,and has a better finished look when painted.
HOBBES-the paints i use are all acrylic paints, i usually use tamya acrylic paints,mixed with water ,but you can use any kind of acrylic or plastic paints,just remember not to use synthetic paints, i just use this paints, to paint for example, the exhaust nozzles of an aircraft.
I hope my answers helped you.
best regards
Pedro
BLIMEY! :thumbsup: :bow: :cheers:
holy ****, that looks awesome :o
very nice scratchwork :thumbsup:
thanks, I know what kind of material you are referring to.
Wonderful work.
Ian
That, Sir, is some very nice work! :blink:
I have thought of the same method, but usually shy away due to the problems of getting an even cross-section when sanding from square to round... though like everything else, it's probably taking the time to practice.
It would certainly take the expense out of making multiple versions of the same aircraft, not having to purchase multiple kits...
I will have to use your work as inspiration and actually get making something.
As an aside, I understand that Ados F2 contact adhesive plays well with expanded foam and won't melt it... or the blue and green varieties of foam, anyway.
You could also probably use a couple of thick coats of primer to seal the foam and get a smooth surface for painting. Maybe it could even seal it enough to use enamels?
Cheers
Rick
Very nice - true handcraft, and a great result! :thumbsup:
Hi everyone,thanks again for your kind comments,now to answer PERTTIME question;to make the hollow areas on the cockpit and landing gear,i cut a rectangle with a razorblade, the rectangle should be at least 5mm in depth,the length and width depends on the scale you are building your aircraft,after cutting the sides of the rectangle just "dig" the inside with a x-knife or small screwdriver, so that it becomes hollow,then smooth the bottom of the area by using a piece of plastic, i usually glue a piece of selfadhesive plastic to disguise the irregularities, the process is the same for the areas of the landing gears.
Rick lowe you make a good point, when you say using a couple of coats of primer to smooth the polystyrene,and that's what i do before painting, but a few years ago i learn the hard way, that synthetic paints meltdown the polystyrene, so now i always use acrylic paints, because they are easier to mix with water or alcohol, giving more time to paint a model.
best regards
Pedro
