Render a Hot Glue Gun
Firstly you need a drawing of a hot glue gun. You can achieve this in several ways.
1, Draw a real one in your D&T department.
2, Copy this line sketch by hand and then in fine-line pen.
Or 3, Ask your teacher for a print out of this drawing.
Now you have your drawing, you can draw over your A3 drawing or you could use the drawing as an underlay if you have some marker paper or a light-box to work on.
Because marker paper is usually 70gsm (Grams per Square Metre) you can see through it – just about.
Various makes of marker pads are available from art and craft stores. They come in A4, A3, A2 and A1 sizes and are usually 70gsm.
As you can see below,�there are advantages and disadvantages to using specialist marker paper, but the most crucial to students is often the cost.
Advantages:
Disadvantages:
This was scanned with the drawing behind and you should be able to just make out the line drawing.
Using either Persian Blue No315 or Blue No317, carefully and quickly block in the main body shape. Don’t worry if it doesn’t look perfectly flat as you will be laying down more colour.
If the blue is not available then use any strong bright colour such as orange, red, green etc.
Using the same pen carefully add another layer into the grooves and a third thin line to create the shadow (arrowed).
Still using the same pen build up more depth and contrast where the arrows are with just a minute amount between layers.
Don’t worry if yours looks a little sketchy as this will add to the character. Just try to keep the edges crisp.
Fill in the yellow details with flat colour using Yellow No106 or Mid Yellow No104.
Carefully add shading using Bright Yellow No404 and Orange No407. Use the edge of the chisel nib if you are using a single tip KC500 pen.
If you are using the line drawing as an underlay then the only lines that should be edged in black pen are the stand, cable and chrome nozzle.
You can simply use coloured pencils and a fineline pen to create the highly reflective effect to the nozzle.
Aim to draw a sort of desert reflection with a black horizon and a little blue at the top for sky.
It’s the high contrast that makes it work so be sure to leave lots of white.
Fill in the cable and grommet using black or cool grey 10 or 11.
Add some blue, brown and black to the stand to create a shiny effect.
Using a white pencil add some subtle highlights to the top of the cable and grommet.
If necessary add white pencil to create some gentle highlights on the body of the glue gun.
If you want to create the reflection, render this drawing in the same way, using the same pens and colours.
Now you have a few choices.
You can scan or carefully photograph this image so that you can manipulate it with photo editing software, such as Photoshop.
Or
You can lay some tracing paper over it then cut out you original glue gun rendering and sit it on top. The tracing paper will diffuse the reflection and create very similar effect.
See how the tracing paper softens the drawing.
It should look something like this.
Then simply position your carefully cut out rendering so that it looks realistic.
Done !
Alternatively:
You can scan or scan or photograph both images so that you can manipulate the reflection and position the two images using photo editing software, such as Photoshop.
In the Layers tab, make sure you have the image layer highlighted and adjust the opacity to about 60-70%. This will soften the reflection and make it more subtle. Remember this is just a background effect so it should not stand out as much as the main image.
Next you can use the Glass filter to distort and further soften the reflection. Depending which version of Photoshop you have the screen may look slightly different to this but the results will be the same.
Click and hold: Filter – Distort – Glass...
After you are happy with any manipulation, you can layer the reflection behind the glue gun and add a simple border.
I always keep borders simple as they won’t earn marks but they do suggest that the image is complete and it can look more professional.
Done !
