FW190 - a plane paper plane

[Guest]

Taking the liberty to intrude in your community of realistic shiny models I'll try to 'sell' an old-fashioned but very cheap modelling type, the cardboard model.

Very accidentaly I met with Fenlander's group-chat message on the net and switched my intention building a Spit to the FW190 being the group-build subject as per 1st of April.

I'm not very certain to be able to get the 1:50 bird ready within 3 moths, but we'll give it a try. 90% of the drawing work is done and in this thread I will try to show a bit readable sequence:

[ATTACH]14556.vB[/ATTACH] STEP 1: A 3d-view of the model can be found on the I-net and inserted into an empty AutoCad drawing. I have the opportunity to use this software but one can use any drawing-pack (preferrably vectorized) as long as the measurements are clearly and accurately presented.

[ATTACH]14557.vB[/ATTACH]STEP 2: Browse the net on the measurements of the type you intend to build.

[ATTACH]14559.vB[/ATTACH] STEP 3: Measure the sizes of the inserted picture

[ATTACH]14558.vB[/ATTACH] STEP 4: Calculate the percentages and the deviations(!) from reality/drawing. If there is an error in comparing length/span/height then you'll have to reconsider your computation, the sketch or your measured values. The height of a plane is very often an arbitrary factor !

[ATTACH]14560.vB[/ATTACH] STEP 5: Decide the scale (your mm : real mm) you want to build, scale the inserted picture to the size of your model and check the measurements of length, span and height.

[ATTACH]14561.vB[/ATTACH]STEP 6: Copy (draw) the picture in a new layer, add centerlines and check wether the model is positioned rectangularly to the grid of the drawing you're working on. If not you'll have to rotate the copied figure adequately.

[ATTACH]14562.vB[/ATTACH]STEP 7: Look for straight elements in the model's fuselage and cut it into as few as possible cylindric or cone elements. I used a FW190 type D as a basis since this was a picture with the fuselage-sections in it that you have to fiddle out by yourself from top and side view only. (I shifted a copy of my FW190 A over the new inserted type D picture).

[ATTACH]14564.vB[/ATTACH]STEP 8: Adapting the 'D-sections' to my A-type by slightly resizing the heights and widths of it.

[ATTACH]14565.vB[/ATTACH]STEP 9: Is the most difficult step in the entire drawing procedure. The construction of the (mathematical) development of the sections. There are many ways to achieve this result and in fact it is a seperate chapter. I finally wrote an Excel-programme based on the (dxf) co-ordinates from the drawing.

[ATTACH]14568.vB[/ATTACH]STEP 10: In order to make 'gluable' sections of the ribs they are copied to a seperate part of the drawing.

[ATTACH]14569.vB[/ATTACH] STEP 11: Each rib is reduced slightly in order to fit it inside the fuselage elements. Taking in account the paper's thickness of 0.2mm.

[ATTACH]14570.vB[/ATTACH]STEP 11a: Offsetting the original shape and deleting it.

[ATTACH]14571.vB[/ATTACH]STEPS 12: All ribs are provided with 'slabs' that are to be glued inside both ends of the fuselage elements.

And since I am out of screendumps this is for the time being the temporary end of the story. To be continued...

Hi gerard, youre not intruding at all, we welcome any type of scale model ,whatever its made out of. I have seen some outstanding card models, and having had a go at one (and failed!!!) i can appreciate the skill involved in making them (not to mention doing the plans too like yourself!) so please join in the group build, myself and all the other members would really like to see your model. cheers tony

I second what Tony says,welcome aboard. I'm looking forward to seeing how you tackle this. Variety is the spice of life as they say.

Cheers

Thanks for your warm reception. Meanwhile the drawing has passed many steps of minor importance and is very close to the stage of colouring. You have a huge range of paints at your disposal and you know how to use them as well ! I even have the impression that most of you prefer this stage of modelling. My Acad-pack however is primarily a technical piece of software and although you're able to create shiny and diffuse objects - using 3D technique - I prefer to use Paintshop for colouring.

I will jump from the ribs straight away to this item.

This is going to be great Gerard, i for one can't wait to see the build up of this 190. Good luck.

Don't overestimate the result John; particularly you shouldn't... Having a glance at the magnificent stuff you have created. Even the close-ups are astonishing realistic. The mud on the tracks a.s.o. a.s.o. Fortunately I realise that using paper/carton one never will reach such results and certainly no diorama's.

For instance fiddling around with a bunch of sketches and photo's, downloaded from the I-net I just used the whole morning driving in all the wing rivets and even only the upper wing part. Even not convinced wether they are the correct number on the correct spot.

Anyhow, it will resemble a 190 when it's ready.

I hope.

Don't leave yourself short Gerard, we kit builders just stick pre-molded plastic together. You are building this from scratch, and using the computer too. I've only just found out what the interweb was let alone using CAD software (i like to give it a go though sometime). I do envy you though, if i make a mistake it's a repaint, you can just hit undo lol.

The ability to take a plain white sheet of card and turn it into anything other than a birthday card or a box amazes me to no end. I've even studied net development once and it still amazes me!

I am looking forwards to the resulting aircraft!

On the comp. yes, you're right, but once paper is glued to paper and the parts are eroneously of a different length.... then it means a redraw, a replot, e recut and a reglue. Building a prototype this is not an exceptional event [ATTACH]14605.vB[/ATTACH]

progress report

[ATTACH]14882.vB[/ATTACH][ATTACH]14881.vB[/ATTACH]

Almost finished drawing. Outstanding are prop, spinner, landing-gear, wingroot fairings and nose-bulges.

As soon as dwg is ready i'll upload the pdf's.

Till then.

This is outstanding work Gerard.

Here she (preliminary) is. Can't yet start building since at the very first print the color-cartridge stated to be empty :-(

page 0

page 1

page 2

In case of an error-message (page error) just change percentage of the pdf-display.

See you soon.

One month late...

Ok guys, it's done.

[ATTACH]17752.vB[/ATTACH]

....

but how can I upload the three (drawing) pdf pages ????

This is µ▒♦╖◙ stupid.... how did I do that previously ?!

Come on guys, this is amazing. Prior to the FW190 GB, Gerard did not have a model of the FW190. As part of the GB he designed and made this amazing Card FW190. No Tamiya engineers and research dept, he did this by designing and creating the drawings, converting it into 3D projections and then printed, cut out and glued together a masterpiece. Congratulations Gerard, you are the master of Card models :no1b::respect1:

[spanner570]

Truly stunning.

Thank you for sharing your amazing skills with us.

It has been a pleasure to see this superb model come to fruition from, in essence, a couple of pieces of paper.
