Template
I threw away the Templates, so I can't upload.

Attention in the work
-When you uses a thing including the thinner(Bond, lacquer thinner etc) or spray, make good ventilation.
And wear a gas mask.
<-I'm using this mask.

-When you toast mterials etc, make good ventilation.
And don't breathe smoke, don't put smoke in your eyes.

-When you dig mterials etc with Soldering iron, make good ventilation.
And don't breathe in smoke, don't put smoke in your eyes.

-Don't use fire near the things which are easy to burn such as paint, thinner etc.

-When you finished using tools, pull an outlet.

-Read labels of materials and tools, and understand how to use.

How to make
Make Templates.
Make ground plan from "Kousakuyousi"(one of hard paper in Japan).
At first deside thick of every blade.
I decided the thick of blade is 2.6mm.



Make Templates of edge of blade.
Cut out 10mm thick EVA foam.
Width of 10mm thick EVA foam is half of decided thick of blade
Big blade is 2.6mm thick,then Cut out 10mm thick EVA foam to 1.3mm width .
Paste EVA foam with double sided tape.



**********************************************************************

EVA foam is a soft material.
You can process it easily.
Another name is EVA board, EVA zote, Craft foam etc.
I usually use one called "Lion board".
"Lion board" is sold only in Japan.

Watch video.

**********************************************************************

Use a sharp blade. For example, "Pro Blade".
This is so sharp.
←10枚入り ←50枚入りお得パック

When you cut, put EVA foam on Cutting mat.
Don't cut in the air, while holding by hand.
Break a b blade frequentry, if you feel sharpness of using blade became bad.
If you want to do work more speedy, use "Running fire box cutter","Blade breaker".
"Running fire box cutter" can have 6 pieces blade inside.
"Blade breaker" can break easy and speedy.


Use Art knife PRO for small ornaments etc.

**********************************************************************


Serve gap from end of EVA foam to "Kousakuyousi"(one of hard paper in Japan) from "Kousakuyousi"(one of hard paper in Japan).

Make a core.
Use a PVC pipe(diameter 26.0mm).
Cut a PVC pipe.
PVC pipe can be cut with a saw.
But a Pipe cutter is more better.
It can cut quickly and neatly.



This is a video of cutting method of PVC pipe, bending method, jointing method.


When you use this, joint with a stick.


Make a stick.
The best length is 25cm.
There are two methods.
-------------------------------------------------------------------------------------------
1.Iron gardening stick and EVA foam
It's take time, however jointing power is strong.

Cut Iron gardening stick. How to cut is here.
Cut out 2mm or 1.5mm thick EVA foam.
Glue with a Liquid instant glue.

-------------------------------------------------------------------------------------------
2.Wood stick
It's a easy method, but jointing power is weak than above method.

Cut a wood stick with a saw.
Shave it with Box cutter as necessary.

-------------------------------------------------------------------------------------------

Glue with a Hot melt(glue gun).
The reason Styrofoam was pasted together 3mm thick EVA foam is
to make both thick same.



Put 0.5mm thick Plastic sheets side by side.
Glue with a Liquid instant glue.
When you use a Instant glue Accelerator, Hardening speed becomes fast.
(Smoke may be generated. Don't breathe in the smoke and don't put in eyes.)


**********************************************************************


Instant glue can glue a large surfaces easily.
But it can't glue a small surface such as this photo well


Then you should use a following spray.
I always use this.
Watch movie.

Instant glue Accelerator
This can glue surfaces in several seconds.
When you use 100ml, you can make a armorset or about three weapons.
←100ml ←180ml ←420ml

About instant glue
I use general liquid Instant glue.


Case of sticking except instant glue.
"Bond G17"(one of liqud glue in Japan) can glue too. It's can glue narrow surfaces too.
But it's take time.
Moreover, when you use Thinned "Bond G17"(one of liqud glue in Japan) as a undercoat,
glued surfaces may melt.
(If you use Gesso, there is no problem.)

Paint a undercoat on EVA foam.
The effects are as follows.

-Color becomes well.
-It becomes hard to come off.
-Gloss comes out well.
-You can save quantity of the paint.

There are two methods.
-------------------------------------------------------------------------------------------
1.Gesso

-Gesso don't contain thinner, then you can use it in the room.
-You can use also Acrylic paint.

-It's easy to come off than Thinned "Bond G17"(one of liqud glue in Japan). (Moving parts in particular)
-It can't use for PVC pipe or plastic sheets.

【Recommendation】
-Weapons
-Armors without a moving part.

-It'st hard to peel off.
-It can use for PVC pipe or plastic sheets.

【Demerit】
-You must thin it.

Don't use fire until drying, because "Bond G17" burns easily. Don' use a Lighter etc until drying.
The parts will be charred in seconds.

【Recommendation】
-All props
(Props with a moving part in particular)

【Tutorial video】


【Undercoat】
"Bond G17"(one of liqud glue in Japan) thined with lacquer thinner
-for big things -for small things

【Paint】
Lacquer Spray or Bottle lacquer paint

-------------------------------------------------------------------------------------------

I use Thinned "Bond G17"(one of liqud glue in Japan) in this tutorial.
But I recommend Gesso for begginers.

Don't use fire until drying, because "Bond G17" burns easily. Don' use a Lighter etc until drying.
