| Hello and welcome to the Spoken Tutorial on Filing a Workpiece

|-
| 00:07
| In this tutorial, we will learn,

|-
| 00:10
| What is filing?

|-
| 00:12
| Various tools used for filing

|-
| 00:15
| Different types of filing

|-
| 00:17
| How to file a workpiece

|-
| 00:22
| And common mistakes while filing

|-
| 00:24
| For this tutorial we require

|-
| 00:27
| A file

|-
| 00:28
| The workpiece to be filed

|-
| 00:31
| Bench Vice to hold the workpiece

|-
| 00:34
| Vernier Calliper to measure

|-
| 00:37
| Try Square to check the workpiece's squareness

|-
| 00:42
| Hack saw to cut the workpiece

|-
| 00:45
| Punch to mark on the workpiece

|-
| 00:48
| And a Ball pein hammer

|-
| 00:51
| Let's first see, what is filing.

|-
| 00:54
| Filing is a method of removing excess material from a job or a workpiece using a file.

|-
| 01:02
| There are various types of files for various requirements

|-
| 01:07
| Flat file, for rectangular cross-section

|-
| 01:11
| Smooth file : for getting smooth surfaces

|-
| 01:15
| Safe edge file : for filing the right angled part of the workpiece

|-
| 01:21
| Square file : for developing square corners & square holes

|-
| 01:27
| Half run file : for filing semi-spherical surfaces

|-
| 01:32
| And Round file : for developing holes & round groves.

|-
| 01:38
| Let’s us now learn the filing process.

|-
| 01:41
| My requirement is a 5 by 4 inch workpiece.

|-
| 01:46
| The job or the work-piece which I have is 5 by 4 inches.

|-
| 01:52
| So let us first cut the excess 1 inch part.

|-
| 01:58
| For this, apply the marking medium on the work-piece.

|-
| 02:03
| You can use a chalk piece or ink as a marking medium.

|-
| 02:08
| Once the medium is applied, mark the work-piece using a jenny caliper, as shown.

|-
| 02:15
| So, I am marking a little less than 1 inch according to my requirement.

|-
| 02:21
| Next, use a punch and ball pein hammer to punch on the marked line.

|-
| 02:28
| After this, place the work-piece parallel to the jaws of the Vice.

|-
| 02:34
| Now tighten it to hold the work-piece in place.

|-
| 02:38
| This is so that we can cut the work-piece easily.

|-
| 02:42
| Next, take the hack saw and cut the excess portion of the work-piece.

|-
| 02:48
| Once the excess part is removed, measure the work-piece once again.

|-
| 02:54
| Yes, the measurement is proper now. I have 5 by 3 inches .

|-
| 03:00
| Now, let’s start filing.

|-
| 03:02
| First we have to select a suitable file.

|-
| 03:06
| I need a smooth edge, so I will choose the Smooth file.

|-
| 03:11
| Make sure that the handle of the file is securely fitted.

|-
| 03:16
| Do not use a file without a proper handle.

|-
| 03:19
| You will end up injuring your hands.

|-
| 03:22
| Make sure that the file is clean before you start filing.

|-
| 03:27
| Using rusted files will damage the work-piece as well as bruise your hands.

|-
| 03:34
| So, now I have selected the proper file.

|-
| 03:38
| Next step is to place the work-piece securely in the Bench vice once again.

|-
| 03:45
| Position yourself at 90 degree perpendicular to the Bench vice.

|-
| 03:51
| Place your left leg in the front & right leg at the back.

|-
| 03:57
| This is the best position for filing.

|-
| 04:00
| Now hold the handle of the file firmly in your right hand.

|-
| 04:05
| With your left hand, hold the tip of the file as shown.

|-
| 04:10
| Ensure that, the right thumb is pressing the handle of the file firmly.

|-
| 04:15
| Now we are ready to start filing.

|-
| 04:18
| There are three methods of filing. They are :

|-
| 04:21
| Straight forward filing

|-
| 04:23
| Draw filing

|-
| 04:25
| Diagonal or cross filing.

|-
| 04:28
| Let’s see them one by one.

|-
| 04:30
| Moving the file lengthwise across the surface of the work-piece is called Straight forward filing.

|-
| 04:38
| In this method, the filing is done by moving the file up & down slowly.

|-
| 04:44
| You can see that your work-piece is getting filed and the excess material is being removed.

|-
| 04:51
| In Draw filing method, the file is pulled towards the body with an even pressure.

|-
| 04:58
| In Diagonal filing method, the file is moved diagonally over the surface of the work-piece.

|-
| 05:06
| The movement of the file is from one corner of the work-piece to another, diagonally.

|-
| 05:13
| Once the filing is done, we have to check the flatness & squareness of the work-piece surface.

|-
| 05:21
| This is done with the help of Try-Square & Vernier caliper.

|-
| 05:26
| To check whether the flatness is proper, place the Try-square on the work-piece as shown.

|-
| 05:33
| Do so at 3 different places on the work-piece.

|-
| 05:38
| Check this against a light source.

|-
| 05:41
| This is a clear indication of flatness.

|-
| 05:44
| If the surface is uneven, then you will see light rays between the work-piece and the Try-square.

|-
| 05:52
| In such cases, you will need to file again.

|-
| 05:57
| Next we will check the squareness of the work-piece by using the Try-square.

|-
| 06:03
| Keep the Try-square on the corner of the work-piece, as shown.

|-
| 06:07
| Now touch the edges of the Try-square on two adjacent sides of the work-piece, like this.

|-
| 06:14
| Check whether the adjacent sides of the work-piece are at 90 degrees to each other.

|-
| 06:20
| If not, then file again.

|-
| 06:23
| Another measurement that we need to do is to check the thickness of the work-piece.

|-
| 06:29
| For this, we have to use a Vernier caliper.

|-
| 06:33
| Place the work-piece within the jaws of the Vernier caliper, as shown.

|-
| 06:38
| Measure the thickness of the work-piece.

|-
| 06:41
| Now repeat this at least on three different locations on the work-piece.

|-
| 06:47
| Identical measurement indicates that the work-piece is even in thickness.

|-
| 06:53
| Now its time to learn what not to do while filing.

|-
| 06:57
| Do not file a work-piece at an angle

|-
| 07:00
| Do not file a work-piece at both the edges skipping the centre.

|-
| 07:05
| With this we come to the end of this tutorial.

|-
| 07:08
| Let us summarise, In this tutorial, we have learnt

|-
| 07:12
