Electrical Power tools

WHAT IS MAINS POWER/TOOLS.

Mains electricity is the general-purpose alternating-current electric power supply. In New Zealand, the Mains voltage is 230V. Which is an a.c. (Alternate Current) This means that the current is constantly changing direction. Mains powered tools are the tools that can only be used Mains power

THREE MAINS POWER TOOLS I HAVE USED.

Welder

Drill

Grinder

TASKS I HAVE USED THESE TOOLS FOR.

Welder- Connecting two different pieces of metal material together for various projects (eg toolmakers clamp)

Drill- Making a various range of holes in different diameters (measured in mm). (eg weather vane drilling holes for the rivets to go into)

Grinder- I have used this tool when manufacturing my toolmakers clamp to grind down my weld to look clean and sit flush with the rest of the surfaces .

WHAT IS “RCD”

Why is it important?

RCD stands for Residual Current Device. It is a device that is designed to prevent any fatal electric shocks if you touch anything that might be live. An RCD will most likely be used in the workplace, or at home. RCD eclectic cables have a switch in them that help minimise the risk of getting any harm from electrical hazards.

WHAT IS DOUBLE INSULATION?

Appliances and tools of this type are called "double insulated". They have two levels of insulating materials between the electrical parts of the appliance and any parts on the outside that you touch. ... Double insulation construction of appliances and tools allows the manufacturer to produce a lower-cost product. Double insulating also helps make a heavier duty cord so they cannot be damaged as easily as other cables.

EXTENSION CORDS.

Why are extension cords a safety hazard? 

If the extension cord is covered, heat is unable to be realised and could combust resulting in a fire. You should always make sure extension cords are visible and if at all possible, not running across highly trafficked areas. They can be a potenetial trip hazard for people walking through the area.

PPE.

No matter what you're doing you should always wear appropriate PPE to protect you from any hazards presented by power tools, such as Dust and Debris. PPE such as goggles, dust masks, gloves, hard hats, and safety boots should be worn where appropriate.

Pneumatic Tools and Power

WHAT IS A PNEUMATIC SYSTEM?

A pneumatic system is a system that uses variable pressures of compressed air to control different tools/attachments to use during your required tasks. The compressed air comes from a device called an Air Compressor.

WHAT IS AN AIR COMPRESSOR?

An air compressor creates and supplies all the power for all the equipment in a pneumatic system. The rate the compressor can deliver air is measured in cubic feet per minute. There are multiple different types and sizes of compressors. Piston or reciprocating, rotary screw compressor, rotary sliding vane compressors. centrifugal compressors.

SAFETY AROUND COMPRESSED AIR.

Compressed air has the potential to cause serious and permanent injuries. the compressed air will cause minor injuries if it breaks through your or anyone else's skin. if the air gets into your bloodstream there is potential that it will travel to your heart and brain and cause permanent damage.

To avoid any injuries while using compressed air make sure all hoses and fittings are securely fitted to the apparatuses that are being used. also, you should never spray others or yourself down with the compressed air as this will cause injuries,

PPE:

Safety is a huge part of any workplace environment so when using compressed air you should always use the correct PPE for what you're doing. for example, when using a dust-off gun you should always use a full face shield to protect your eyes from any debris that will be flying around. One hundred percent of the time when using any power tools you should be using ear defenders and safety glasses to protect you from noise and debris.

Rendering Internal

Standard: AS91066
In DVC we are doing an internal on rendering. We had to design a bottle at the start of this year and now we are rendering it. We had to render it in three different materials. They were solid plastic, metal and clear plastic.

What did I like? i like my design as its simple and effective 

What didn't I like? I'm not a fan of my rendering technique

ART UPDATE T3

Here is an update with one of my current folio boards

Week 2 Term 3 ART Update

This year my kaupapa in art is City and Urban world I’ve been working on little art prices throughout the year. Here are a few pictures of what I’ve done so far

 -this is one of two art pieces that I have made of a park bench I think this one here is not the greatest as I was still getting used to watercolours. I like the use of colour for the wood but just needs a bit of improvement overall

 This is a digger that I drew in charcoal as I was going to try to incorporate the construction, side of the city theme into my portfolio. This piece could do with some more detail and refinement and I think this piece would look better with a more of a detailed background.

 This here is one of my favourite pieces I have done to date it has two variations a coloured one and a black and white one both of them have a small amount of detail.

I made this piece as a test of how watercolours blend and mix to help me get a little more skill I think if I went over the painting again and layered some parts up it would look quite good

this photo here shows the charcoal drawing I made of the sky tower I feel as it is out of proportion and needs redoing as I feel like I rushed through it

This was another drawing where i tried to add the construction side of the theme in. as you can see the crane in the background and the layered building that is getting built

This is also another one of my favourite pieces it a very abstract piece compared to all my other works but I think it works well and looks good

I

here is the start of another abstract art piece where I've just gone over the paper randomly with different colours

JOJO RABBIT ANSWERS

1. because it's a different way of showing how people were thinking as adults can choose their thoughts as this happened later in their life whereas Jojo was brought up into a nazi society, therefore, it's all he's grown up knowing

2. if the text was written to be based around an adult I think it would have a completely different storyline as some of the adults had very strong beliefs and had a smallish idea of what they were thinking.

3. He used a child's perspective as this helped show the audience how the nazi era had an impact on children while being able to use an aspect of humour through childlike behaviour.

4. The children in the Film are represented in a way that shows they are curious and questioning what's going on whereas the Adults are represented in a way that shows they are very opinionated and believe in what they think

5. I think that during the film Jojo used his imaginary friend Hitler to help him get through different stages during the film this was shown in one of the starting scenes where Jojo was getting bullied so he ran off and "Hitler" said some things to him which inspired him and he ran off all happy
