Hi to all. This is the model that I have decided to make. With this post, I begin my step by step. This, will be useful for all the scales. Now. I'm planning all the pieces that I need. Soon I will begin with the pictures.

Pedro,

Thank you so much for taking the time to post a step by step build log here with us at Armorama. I personally am very grateful that someone of your talent would take the time to give us all here an insight to your scratch building voodoo magic

Especially in this small scale we often find that not only are parts missing that should have been included with the kit but are also not available via the aftermarket, leaving us somewhat frustrated. Of course the only other alternative would be to scratch build the item. And without the skills, tools and basic techniques it isn't easy to accomplish. And then there is the limitations of the injection mold process that leaves us with large blobs of unrecognizable shaped plastic to represent the smaller details items in the kit. This is true even in the larger scales too.

Anyhow, I am very pleased, overjoyed and happy that you have a little time for us. I will be taking a seat up front for this one as I am sure all of us here will too!

Preform your magic the floor is yours . . .
-Eddy

Hello Pedro. You have chosen an unusual subject to model, good luck with it. I will be watching your progress.

First, you must remember that they are only my techniques.For you, they can be useful or not.

PLANNING THE DRAWINGS.

I think this is the most important step for our model. For this, we can use some programs of drawing very useful in order to make a good job (Corel draw, freehand, adobe ilustrator). We will draw all the pieces again with their views (front, sides and down or upper). Before, I used plotting paper, but the pieces had different measures and I had to repeat the pieces two or three times. Now, all the pieces has the same measure and I can to make my models with a great security.
First example.
With three different views we draw the chassis exactly.

Second example.
The radiator ready for print. Later, they will be very useful to cut the pieces over the plastic.


It will continue………

Pedro.

TESTING THE DRAWINGS

Well, we have ready all the basic pieces that we need to begin the model. In this step we will prove our drawings.

The pieces, grouped by modules.



Now, we will remember when we were young. We will make a paper model, in order to prove the pieces.




The paper model are ready. We can to see that all the pieces fit correctly.



Now we can to cut the pieces in plastic.

Great trick using Corel.
I know how to use Autocad and now I can put this knowledge in use when I model.

Pedro,

I have an older version of CorelDraw and AutoCAD too! I never thought of using these programs for scratch building. Great concept. Both programs are rather expensive for most modelers.

I found a free program online for those on a tight buget that has most of the features included in AutoCAD to be able to achieve drawings like the examples that you have shared with us. The program is DoubleCAD XT by IMSIDesign. It is very user friendly. And yes there is a learning curve with this program but worth the time you invest into getting to know the program. I found it over at Downloads.com for anyone interested?

Hi Eddy, all programs, are rights for this steps. I only mentioned the most famous.
Well, we continue with the step by step.

CUTTING THE PIECES




We print the drawings and glue these on the plastic using adhesive bar.

We mark the lines without cut. We can to drill the holes for rivets, windows, etc.

Using ours fingers, we eliminate the rest of the plastic. Later, we will eliminate the paper with water. Now, the pieces are ready for be glued.


Regards. Pedro

A question about the forum. How I can edit my old posts? In Forum FAQ say "You may edit your own posts at any time," but now I can to edit only the last post during some ours.

Are there any problem with my old pictures in this post?

Pedro,

I am happy that you are taking the time to inform and teach us some new and interesting ways to help us all in scratch building our own stuff. Keep it coming! I would have never thought about using a water-soluble glue stick to attach the printed drawings onto the plastic. Hummm

Concerning your question about your inability to go back and edit your post? Well it seems that a certain member here at Armorama had apparently gone back to some of their previous postings and deleted them. So the staff here at Armorma decided that it would be in the best interest to all to limit the amount of time we could go back and edit our posts. My understanding is that we now have an hour after posting to go back and edit. After that the edit button disappears.

Thank you,
-Eddy

Eddy, it was the best way in order to use my drawings.

At first, I want to remeber that these are only my techniques. Perhaps, I'm explained things that all people know.

Well, I continue with the model. I have ready the first pieces.

Now, I want to use electrical cable to make the hoop on the radiator. Always, the problem is that the cable is doubling. Well, we shall use a rule in order to repair this.

Thanks guys.

When I have the cable ready, I always glue these (and all metallic pieces) with tamiya cement. This is the best way in order to put the pieces correctly. Finally, I glue these with ciano, using a fine electrical cable.

Thanks Daniel.

Now, I am with the chassis. In this step, first we will cut the plastic pieces and they will be glued on the paper drawing with the adhesive bar. We can to cut the pieces exactly. Second, we glue the pieces with tamiya cement. The paper will absorb the rests of the glue. We only can to do this with little surfaces.



Radiator, engine compartment and rear box over the chassis.

Thanks Paul.

MAKING CIRCLES

I follow detailing the chassis. We need to make the trasnsmision and the engine steering wheel. For this, we normally use a compass, drawings, etc.. but not always we make perfect circles.

Some pieces we can to make with this step.



The material that we need. The most important. A glasses. Drill, caliber, scribers (homemade).



With the scriber, we cut the external circle.



With the caliber, we adjust the external circle using a file or the scriber. We have ready the circle.



If we want to make a hoop, with the scriber, we cut the internal circle. We use again the scriber in order to adjust the internal circle.



We have ready the hoop.



An important considerations in order to avoid the deformation of the plastic .

1.You must remember that you need to be patient and to have some practice. The first time, second....you will say asrfkjasdkfsañlsdjfaggggggggggg.....
2.You must to maintain the scriber sharpened.
3.You must not to press strongly.
4.You must to retire the scriber frequently.

Hi Pedro

I think your thechniques are very interesting indeed.
For my job i use a drafting software and me too i was thinking how I'll can use it for model works.
It's very clever your way to obtain the paper jigs

I'll follow your tread carefully

Thanks a lot for sharing

cheers

Pedro,

I have been following your step by step and find it very interesting and useful. I would like to know how you created the louvers on the engine side panels? Did you shape each louver before you set them into place?

Great tip for creating the circles and tools you've made for cutting out the circles.

thanks to both.
Eddy, scribers was an idea of a Spanish modeller, my friend Jose M. Clavero.
To make the louvers is very easy. Three pictures.

Pedro,

Thanks for posting your process for creating the louvers. I've always wondered how these were done. So simple!

I went ahead and made a set of cutting scribers per your step by step method for making circles and have been doing a little practicing. Monkey see, monkey do!

Hi Eddy. I hope you can to make excellent circles with the scribes. These, are very useful to cut, mark, etc.

Well, this is the first progress in my model, applying the technics that I have explained in my step by step. Now I only are with general forms.



I'm waiting some help with the chasis because I haven't a good information.

Hi Pedro

its fascinating seeing what you do, and how you do it.

good on you for taking the time to take pictures and explain how you do it

it makes for compulsive reading

cheers
