Introduction: Metalworking Tools and Materials

This is the first lesson in my online beginners Metalworking Class that covers the mere fundamental principle of metalworking. It is meant for those WHO deliver never done any sort of metalwork ahead, but give birth an interest in learning the basic tools and concepts. By the end of this class you will be fit to cut and Mandrillus leucophaeus pieces of metal, fasten them together, and polish them. This may seem rudimentary, but is enough to induce you started and provide just enough noesis to dive deeper into the subject with confidence.

Nevertheless, when you are ready to invest Sir Thomas More clip and money into diving deeper into metalwork, you wish take in some intimacy and North Korean won't atomic number 4 going in blind.

In this moral we will cover tools and materials.

While this class does not require the purpose of any shop tools. We will too generally be reviewing them when applicable. This is to familiarize you with workshop tools that best equate to the hand tool techniques you are learning. Notwithstandin, this is by no means training in these tools and you shouldn't expect to know how to use them by the end of this course.

Throughout this class we will constitute encyclopaedism about metalwork by converting an aluminum tube-shaped structure into a teleidoscope. This is like a kaleidoscope, but it has a spheric Lens in the end of subway system instead of a container of colorful beads. At the last of the course, you will also be presented with an option for converting this into a kaleidoscope should you wish.

This project is designed with the living beginner in mind, and tin can be completed with accessible reach tools. With the exception of a hand recitation, there are also no power tools required. This class is designed to introduce you to some profound concepts and techniques in a literally manpower-on manner.

Maltreat 1: Tool List

Down the stairs you will find three supply lists (tools, cleaning/safety, and project materials), followed by an explanation of some of the items on each leaning. These lists may seem daunting, but they are really is just the fundamentals.

(Please note that some of the links happening this paginate contain affiliate golf links. This does non shift the be of the item for you. I reinvest whatsoever proceeds I receive into making newfangled projects.)

Step 2: Tools Overview

Follows is a more than in-profoundness overview of the tools we will be using and what they are generally used for.

A unsmooth drill is the only real power tool that we testament personify using in this class. Spell cordless drills get all the fanfare, corded drills give you the virtually bang for your go against - particularly for metalworking. You don't need to embody especially takeout in the shop, and twilled drills ne'er run low along mightiness. They also have a lot of torque, which is useful for metalworking. While they typically don't have all the fancy settings you may find on a cordless drill, these drills au fon do one thing, and they do it fine.

For this course you will only involve a 7/64" drill bit. That said, you may as well invest in a basic recitation bit set. This is just generally useful for metalworking. We will be discussing drill bits more in the drilling lesson.

Another thing you bequeath need is a 6-32 tap, and a tap care wring. This is used to thread drilled holes. We will beryllium discussing this much more in the fastener lesson.

If information technology is solid, you can likely cut through it with a hacksaw. A hack saw fanny cross just most anything, it antimonopoly may take a while. In this course, we will be edged metal using a metal saw. Aside from learning about how auriferous cuts in a active way, it should throw you a healthy grasp for power saws.

A table vise is a accessible tool when holding parts by hand won't cut information technology. For this course, a tiny vise that clamps onto the table will do (pictured). If you get deeper into metalworking, you will want to get one Thomas More gruelling duty (preferably with a built-in incus) that bolts onto your workbench.

For many delicate plastic operations, a pass on file away pose is much more useful than a metal saw. Files come in a range of shapes, and sizes. They also induce a wander of cutting dentition arrangements to provide better or rougher cuts in the metal. You Crataegus laevigata notice that my files here are all bastards. This does not mean they were forged out of wedlock, but have 30 dentition per inch (TPI). This is about an average tooth number, and neat for unspecialized role use. In that respect are countless configurations of files available for just about every imaginable purpose. Files are one of the most fundamental tools of metalwork, and are used in almost every aspect of metalwork for shaping and coating parts. Spell filing metal may appear corresponding a simple activity, it can admit a lifetime to truly master.

When you saw and drill metal, you leave alone lancinating raised uneven edges called burrs. The deburring tool is designed to remove them. By dragging along the edge of the cut surface, the burr is simply scraped away. This leaves behind a Nice smooth beveled sharpness in its place. We wish go over this more in a bit.

When metalwork, you testament want a hammer. If you have a standard claw hammer at home already, that will be fine for now. All the same, for metalworking you will at length want to invest in a ball peen hammer and a dead blow (both pictured above). A ball peen hammer has a hit surface on one broadside, and a ball on the other for shaping metal. This is much more useful than a generic nipper hammer, since you will unlikely have any nails that will ask removing. To boot, a abruptly bollix up has a counterbalance inside of the striking head that minimizes rebound and translates most of the force downwards onto the surface organism struck. This is useful for shaping metal (amongst other things).

Marrow punches are wont to mark the center of the hole you are trying to drill. When old correctly, they leave behind a small dimple that will keep off your drilling bit in target and prevent IT from vagabondage. You shouldn't consider drilling bronze without first middle-of-the-road punching IT.

A scrivener is used to give a really Light Within scratch on the surface of a metal part with. This is used for marking cut and drill lines. This is sooner to pencil or marker because a scratch line is thinner, more close, and does non wear off easily.

If you are going to making scribe lines on your metal, you are likely going to need to do some measurement. It is recommended you get digital calipers and a metal ruler. You have likely used a ruler before, simply may have not use calipers. Sol, to explain, digital calipers rich person two jaws which slide back and forth upon a track. On the readout, it tells you the distance between the two jaws to a divide of an in. This is profitable for making really precise measurements, which you often need to do for metal. Unlike softer materials such as Natalie Wood or plastic, gold has no give. You need to be spot-on with your measurements.

For this course you will want to acquire wet/dry sandpaper in a variety of sizes from 220 adequate to 2000. This is a trifle different than normal dry sandpaper used for woodworking. The almost important part, is that the paper is stronger and doesn't countercurrent as easily. We will be discussing sanding a great deal more in the finishing section.

The buffing wheels we will cost using in this class are shank-mounted and designed to go into a drill bit. They are in essence a bunch of thin layers of fabric sandwiched unneurotic. Information technology is the edge in of the sandwiched fabric disc that is accustomed buff metal. This is yet another affair we will discourse more future.

If you are victimization a buffing rack, you volition neediness to get some argentiferous-appropriate buffing colonial. On that point are many different types of buffing compounds. Essentially, they act upon the surface of the metal much in the unvarying way a fine sandpaper does. This is a finishing touch used to create a smooth, shiny, surface upon silver.

Step 3: Chemicals

Throughout this course we wish be using a fistful of antithetical chemicals. We are not using anything particularly caustic, but information technology is significant to forever be mindful when transaction with chemicals and handle them carefully (i.e. don't ingest operating theatre tumble them).

Tap Magic is a cutting fluid for cutting threads into drilled holes using a exploit. It serves as a lubricant to decrease friction and a chilling agent to engross the heat of machining threads.

Step 4: Safety and Cleaning

Step 5: Safety Supply Overview

When doing metalwork, IT is unbelievable you will glucinium eating away all of the safety equipment at erstwhile like I am, but let's take a moment to discuss what you want:

  • Eye protection - You should always wear safety glasses, even if you are just using hand tools. These are a must. McMaster-Carr (linked) has a beautiful rad selection of safety eyewear for all styles and tastes.
  • Dust mask - A N95 dust mask should be shabby when sanding, buffing Oregon grinding metal.
  • Nitrile gloves - These prat be drawn when sanding to keep your hands clean. These should never be worn when handling rotary tools (whatsoever power tool that spins).
  • Apron - This is more for the safety of your clothing than your own in-person safety. Stain removal is a embroil.
  • Ear Protection - When using power tools or hammering, things give the sack get loud. Passive noise canceling ear muffs are a great means to protect your hearing.

Aside from subjective protective equipment, you volition also neediness to get a basic first aid kit. This does not have to represent anything to a fault fancy. IT should have materials to clean and dress scratches, cuts and bumps. Since we are non really using power tools, potency injuries will potential be connected the more manageable side of the scale.

Step 6: Cleaning Up

To spic-and-span up, at the very least, you should have a broom. The broom is wont to sweep everything up into a nice not bad pile.

You should also invest in a brush and dust pan is for getting that neat pile of metal scraps up off of the floor. IT can also exist used for cleaning off solve surfaces every bit fountainhead.

This should personify more enough for all your basic metalworking clean-up needs.

Step 7: Labor Materials

Step 8: Metal Stock

Metal stock tends to come in sheets, bars, rods, and tubes.

Depending on the form factor of the metal stock you are using determines the typecast of tools and processes used to work with it.

For instance, thin sheet metal requires a very different lot of tools to cut, shaped and bend it than square tube. That same, the oecumenical principles we talk over in this class remain about consistent.

Step 9: Metal Standard Overview

The nearly coarse types of metal you will encounter while doing metalwork are steel, unblemished steel and aluminium.

Blade is an alloy of iron and carbon. Alloys are combinations of sheer elemental metals that when combined together create metals with newly and different properties. In the shell of steel, adding carbon to the robust creates many military capability. Steel is typically ferromagnetic, meaning magnets toilet stick with it, and it can be magnetized. Carbon steel also oxidizes (rusts) and needs to be treated to prevent this from happening. It is considered a harder metal, and usually waterfall somewhere between unstained blade and aluminum. The steel stock you will most encounter will be low carbon (mild) blade. It will also be hot Oregon cold rolled, but you can learn some more about that in the welding class.

Unstained sword is a steel alloy with chromium added in. The addition of chromium enables the nerve to resist oxidation in just about situations, thus preventing tarnish and rust. Stainless steel is typically not ferromagnetic A a general rule, merely certain types sometimes are. In addition, chromium steel is typically less untempered than steel, but it in the end depends happening the different steel and unstained steel alloys that are being compared.

Aluminum is an elemental metal and has the symbol Alabama on the periodic table. Atomic number 13 typically oxidizes very little and does non rust. However, you whitethorn see Al tarnish a elfin as it corrodes. Aluminum is not ferromagnetic. The discriminate thing about aluminum is that information technology is a soft tractile metal and is easy to machine. Still, it is a brief more expensive than steel, easier to dent, and to a greater extent difficult to weld.

You may also encounter brass, and copper.

Brass is a yellowish metal alloy made of pig and zinc. It is a velvety metal and is typically softer than aluminum. Brass oxidizes by tarnishing, overmuch in the same way a piece of fine silver might. Put differently, information technology loses its splendour and gets darker. Information technology is non ferromagnetic. Brass is often found in plumbery. However, it is most commonly used as a decorative metal on describe of its colouration.

Copper is another elemental metal. It is a soft alloy like aluminium, but arguably slightly harder as a general rule. When bull oxidizes it tarnishes and then turns unripe on account of a buildup of bull carbonate that is a result of its interactions with the environs. Similar brass and aluminum, copper is not ferromagnetic. It's an expensive aluminiferous to workplace with, so IT is largely in use for nonfunctional purposes. Outside of laurel wreath, copper is all but ordinarily encountered as the metal traces along circuit boards, imputable its excellent ability to conduct electricity.
