Brainstorm (or Free Association):

Free association. What this means is that we have a web of memories that are connected based on related features. Through this, seemingly distant concepts can become connected to each other. For example, seeing a pineapple in the grocery store might remind you of Hawaii which then reminds you of a past vacation with family, and suddenly you’re feeling nostalgic for that relaxing time. See the figure below for what this web of free associations looks like. These connections take you in unexpected directions and make unexpected/original connections. A powerful tool for ideation!

Hardening – Hardening steel involves heating it up to a particular temperature and then rapidly quenching it in water, oil, or whatever medium is appropriate for the specific alloy. However, the steel has to have sufficient carbon content for it to harden. Depending on the application, the hardening process frequently leaves the steel too hard-similar to a piece of glass. So the tempering process is used to “take out” some of the hardness, leaving it hard enough for its intended purpose but with enough ductility to be tough. Obviously, this is a very simplified description of the process but I think you get the idea.

Steel changes colours at different temperatures. So you can see how hot the steel is by carefully watching its colour as you heat it. Once it reaches the correct temperature, quenched it in oil or water (oil is the proper quenching medium for spring steel). Keep it completely submerged in the oil, and swirl it around in the oil until it cools off. Then remove it and clean it off for the next step: tempering.

I will add a detailed explanation asap.

Jig – is a device that allows you to repeat procedures accurately – this could be cutting or drilling or even folding. In this case this is a professionally made jig for the drilling of Kitchen door hinges:

• Preps doors for 35mm Hinge Cups and 8mm screw holes
• For drilling holes for hinges with either screw fixing or pre-mounted euro screws
• With template for wing mounting plate
• Bit for hand drill machine
• 2 x drill Ø 8 mm
• 1 x drill Ø 35 mm
• Bit for boring machine

drilling jig 2So this jig (using a portable electric hand drill) allows you to drill holes for two screws and bore a hole for a recessed spring mechanism, over and over again. Of course you can make much simpler jigs to help you drill holes accurately in your work with just a couple of bits of scrap wood.

Printing (Litho vs Gravure)

A quick look at the key feature, process and benefit differences of Gravure and Web Offset printing:

  • The gravure printing process has the ability to print a smoother image and more consistently on lightweight papers.
  • Web offset printing presses have fixed cylinder cutoffs, whereas gravure presses have a variable cutoff dictated by the cylinder diameter used.
  • Web offset dots are printed as a round dot; gravure ones are hexagonal.
  • Web offset uses a printing plate; gravure a cylinder engraved with cells which carry ink.
  • Web offset is an offset printing process, whereas gravure is intaglio (i.e. the cylinder comes into direct contact with the paper and is not offset).
  • Web offset inks are dried by heat from a gas oven. Gravure inks contain a solvent called Toluene which, as well as being toxic, evaporates, hence drying the ink without heat.
  • Web offset presses can print either long or short grain; gravure prints short grain, due to folder configurations.
  • Web offset printing is suitable for 8pp A4 sections upwards from runs of 50,000 upwards. Normally gravure will print sections from 8pp to 168pp in size and is competitive for runs, usually, from several hundred thousand to millions of copies.
  • Web offset plates will run for around a million impressions; gravure cylinders, which are coated in chrome, can last for over 20 million impressions.
  • The set-up costs of a gravure press are several times that of a Web offset printing press – hence the size of run needed for the process to be competitive.

Tempering: After hardening, the metal is too brittle to be usable, so it needs to be tempered. Steel needs to get to about 600 degrees for tempering. Use the colour of the steel as a guide to its temperature, which is indicated by the steel being a blue colour. In order to be able to see that, the steel needs to have the black colour from the oil quench scrubbed off. Quench in oil.
