I decide to construct the light stand based on the instructions from
link posted by neXus.
CONSTRUCTION
I first picked up a useless cardboard box from office.
This size is small enough to create a trial prototype.
The dimensions of the box was just right for me to shoot a 1/144 scale.
I cut the windows into the sides with 1 & 1/2 inch borders, as instructed. Namely the 4 sides of the box. I feel that just the top, left and right are necessary.
I put the box up and sealed the box into shape with masking tape.

I applied adhesive to the window frame using glue stick and applied the diffuser. I have used 70gsm white A4 copy paper as the diffuser.

I briefly layed 2 pieces of A4 copy paper (same as diffuser) as the background. I have not done a continuous background as instructed by the tutorial because this is just a trial prototype to see if this project is worth continuing.
I know that I should use a fluorescent daylight lamp for this trial setup, but I wanted to see if I can make use of my incandescent lamp. Basically, incandescent lamp is 'warm' light and has a yellowish tone.
THE TEST
Camera: Compact type Canon Ixus 40
Subject: HG Gouf Ignited Yzak Custom
Lighting: Incandescent Lamp x1, No Flash.
Test #1 Incandescent Lamp
Parameter: Custom WB (Fluorescent)
Setting: F/2.8, Exposure 1/13s, Exposure Compensation 0.
Test #2 From Top
Parameter: Custom WB (Incandescent) fromTOP
Setting: F/2.8, Exposure 1/20s, Exposure Compensation +0.7.
Setting: F/2.8, Exposure 1/30s, Exposure Compensation +0.3.
Test #3 Direct from Front
Parameter: Custom WB (Incandescent) Direct from FRONT (outside tent)
Setting: F/2.8, Exposure 1/40s, Exposure Compensation +0.7.
Setting: F/2.8, Exposure 1/50s, Exposure Compensation +0.3.
Test #4 From Side (Right)
Parameter: Custom WB (Incandescent) from Side (Right)
Setting: F/2.8, Exposure 1/13s, Exposure Compensation +0.7.
Setting: F/2.8, Exposure 1/15s, Exposure Compensation +0.3.
CONCLUSION
I have white balanced with the background as reference and kept the pictures unPSed.
The diffuser filters off quite a bit of the light. Any immediate impact of the light on the kit is visible from Test #3, where the white areas on the Gouf Ignited looks to have a tinge of yellow
The lamp from the top (Test #2) and side (Test #4) gives identical colors. However, Test #1 results in a darker shade on the face and body while Test #4 shows the whole MS clearly, but casts a shadow to the left side. Hence, I believe that with 2 lamps on the sides will yield the best results. Over the top lighting may not be necessary.
All in all, the light tent does reduces the shadows to a certain extent.
Understanding your camera is important and not all cameras are the same. Play around with your settings to get them right. I have used the lowest ISO to reduce noise, hence I need to compensate by stepping up the exposure. I tried +0.3 and +0.7 and felt that +0.3 works best for me. By stepping up exposure, I am prone to blur pictures. Hence, I have used a tripod and a short timer to take the pictures.
I am definitely going to scale up and build a large one, so that I can engage the subject from more angles. I will be trying out different diffusers along the way, while I will still use mahjong paper. I will be using various coloured paper as background (for this trial, I shouldnt have used white over a white model).
If you are keen on trying, Things you need:
1. Cardboard box
2. 2x Fluorescent/Incandescent Table Lamps
3. Mahjong paper
4. Coloured paper
5. Masking tape
6. Pen knife
7. Scissors
8. Glue stick
9. Ruler
