1 Jointer Welcome to a tutorial video discussing how to safely use and operate the jointer.

2 Used to true the edge of a board 2nd machine in procedural order
Overview First a brief overview. The jointer is used to true or straighten the edge of a board. Typically, it is the second machine used in the procedural order after the planer Used to true the edge of a board 2nd machine in procedural order

3 Fence Blade Swing Guard Outfeed Table Infeed Table On/Off Switch
Now, let’s identify the important parts of the jointer. They are the on/off switch, fence, blade swing guard, infeed table and outfeed table. On/Off Switch

4 How long is my board? Needs to be 10” or longer How long is my board?
In order to be run safely through the jointer, a board needs to be at least 10 inches long. Needs to be 10” or longer

5 Depth of cut should… …NOT exceed 1/8”
The depth of cut should never exceed 1/8 of an inch. Luckily on our jointer, the machine is permanently set to this measurement. Unless it vibrates loose, you will not have to adjust this setting. …NOT exceed 1/8”

6 Keep the swing guard …over the blades
Always keep the swing guard over the revolving blades especially when the machine is running. This will minimize the opportunity for injury. …over the blades

7 Pick one edge to joint Pick which edge of the board you want to joint. I typically choose the straighter or smoother edge of the two.

8 Always wear your safety glasses

9 Turn the jointer on Press the GREEN button
With this basic knowledge, you are ready to turn on the jointer. To do this, press the green button. The machine should instantly turn on. Press the GREEN button

10 Push it through smoothly
With the jointer running, push your board through in a slow smooth motion. Repeat this process until the edge of your board is smooth and straight. Keep in mind that you should only joint one edge of the board. While jointing both edges will result in two smooth sides, there is no guarantee that the two edges will be parallel with each other. We will straighten the other side later on the table saw. Repeat as needed

11 Now your board has… …a smooth edge
Now you should have a straight and smooth edge on your board. If not, keep jointing it until you do. …a smooth edge

12 Turn the jointer off Press the RED button
When you are finished, turn the jointer off by pressing the large red button found below the green on button. Press the RED button

13 Danger!! Danger! Use a push stick if your fingers will be closer than 4 inches to the blades of the jointer. In this situation, I should use a push stick. Use a Push Stick!

14 Safe!! Here I am using a push stick to joint this narrow piece of wood. By using the push stick, I am able to maintain the 4 inch margin a safety required for this machine. Use a Push Stick!

15 Safe to use hands if… board is higher than fence
You do not need a push stick if the board’s width is greater than the height of the fence. board is higher than fence

16 Danger!! Do NOT joint end grain
Danger! Never joint end grain. If you need to cut or straighten the ends of your board, you should use the Power Miter Box Saw. Do NOT joint end grain

17 The end splits out Do NOT joint end grain
If you unwisely decide to joint the end of your board, the ends will split out and ruin the smooth edge you just made. Do NOT joint end grain

18 Danger Overview Using stock that’s width is less than the height of the fence without a push stick. Using stock that is less than 10 inches long. Removing more than 1/8 of an inch per pass. Standing directly behind the wood—possible kickback Let’s review four safety hazards associated with the jointer. Using stock that’s width is less than the height of the fence without a push stick Using stock that is less than 10 inches long Removing more than 1/8 of an inch per pass Standing directly behind the wood be jointed due to the possibility of a kickback.

19 Before you start… How long is my board? Which edge do I want to joint?
…answer these questions How long is my board? Which edge do I want to joint? Anytime you are going to use the jointer, first answer these questions: 1. How long is my board? Remember, your board needs to be at least 10 inches to be safely run through the jointer 2. Which edge do I want to joint? Choose the straighter or smoother of the two edges on the board

20 Review What is the minimum length of stock to be run through the jointer? 10 inches How much material may be removed in one pass? 1/8 of an inch Should both edges be jointed? No, the edges won’t be parallel Review Questions 1. What is the minimum length of stock to be run through the jointer? The minimum length for a board to be safely run through the jointer is 10 inches 2. How much material may be removed in one pass? The most material that can be removed in one pass on the jointer is 1/8 of an inch 3. Should both edges be jointed? No. While the two edges may be smooth and straight, there is no guarantee that they will be parallel to each other.

21 Review What is the margin of safety? When do you use a push stick?
4 inches When do you use a push stick? If the board’s width is less than the fence’s height Where should the guard be? Over the blade Should end grain be jointed? No, the ends will chips 4. What is the margin of safety? The margin of safety is 4 inches. 5. When do you use a push stick? You use a push stick is the board’s width is less than the height of the fence 6. Where should the guard be? The swing blade guard should always be over the blade 7. Should end grain be jointed? No, the end will chip out. Instead use the power miter box saw

22 Questions? Comments? If you have any questions or comments, please review this video again or contact your instructor. Thank you for watching.
