Metalworking
An Introduction to Tools and Materials
"Metalworking is a science, art, hobby, industry and trade. Its historical roots span cultures, civilizations, and millennia. Metalworking has evolved from the discovery of smelting various ores, producing malleable and ductile metal useful tools and adornments. Modern metalworking processes, though diverse and specialized, can be categorized as forming, cutting, or joining processes." -Wikipedia, Metalworking (taken 7/22/2020)

Modern Metalworking
The strength of metal lends credence to any project. Sparks fly and welds bind. Cutting, grinding, bending and welding are the modern metalworkers techniques. Beyond those basics: there is milling with a CNC, turning on a metal lathe and water-jet cutting. The techniques in metalworking seem are ever expanding.
MakeHaven Badges for the unit: [The 'minimum badges' on this page are still in development]
Minimum: Shear/Brake/Roll, Metal Drill Press
Metalwork starter: Spot welder, metal chop saw, belt sanders, wire wheel, metal brake, angle grinder, metalwork drill press
Welding suite: MIG Welding, Oxy Acetylene Welding, Spot Welder, Stick Welders, TIG Welding, angle grinder
Metal machinist: Bridgeport, Tormach PCNC440, Metal Lathe, Metal drill press, belt sander
For the course, we recommend that you get as many of the badges above as is practical. Also, it is really helpful if you have earned them before the needed unit, so their acquisition does not eat in to your time to finish assignments. Coordinate with facilitators to complete badges.

For now, we are focused on working with the metal itself, and the metal tools. Get some badges and start working on any kind of metalworking project.
Sheet metal is a great way to get started with metalworking. As long as it is not too thick, it is easily bent and there are many ways to cut it neatly. Folding plans are also great!
Adam Savage is an essential maker, and has come to own this place in the broad maker community.
The 'giant nut' video is a good example of the process for learning a new skill.

Introduction to Metalworking Processes
Metal as a material
Metals of the periodic table - there are lots!
metal domains and magnetism
electrical conductivity
Blade edges - knives, chisels and card scrapers
grinding, smoothing and sharpening metal
Hardening & Annealing Metal
marking & blackening fluid for metal
electroplating
Welding
This week is dominated by processes & material properties. While we want to stay on topic with metals, it is also worth it to see how these ideas can apply to other materials as well...
Weld something! It could be your first-ever weld, or a piece of metal art. Either way, this week you should join two pieces of metal.
