The chunk key or the lathe tool has been used for many years. You will find this tool at any mechanical shop, and you might also require it. So, in today’s article, we will learn how to make a lathe tool from scrap metal.
In the next section of the article, let us go through the list of supplies that are required to make a lathe tool from the scrap. They are as follows:
- Scrap Metals
- Machifit 5C Collet Block Set
- 5C Type Spring Collets
- Lathe Cutters
- Mill Cutters
- Emery Cloth
- Threading Taps
Steps To Make A Lathe Tool From Scrap Metal
Step 1: The first step is to take a skinny steel piece that will be used for the crossbar
Collecting the Steel Piece
Step 2: The second step is to use the AutoCAD tool and draw a CAD model of the Lathe Tool
Designing on AutoCAD
Step 3: Once you complete the design, take the printout of the design.

Step 4: The next step is to lock the steel piece into the machine and drill the center taper.

Step 5: Now, you must start cutting the iron piece into three diameters.

Step 6: In this step, use the emery cloth and shine the surfaces.
Shining the Surfaces
Step 7: After shining the metal surface, measure it once according to the design.

Step 14: The next step is to adjust the middle diameter of the new tools and shank it to half so that it would fit into collet-sized 0.500.
Adjusting the Diameter
Step 15: Place the block inside the Mill-Vies to find the edges. You can perform some test cuts to check.
Adjusting the Edges
Step 16: Now, swap the end part in the collet, and thus, you will be able to drill and chamfer through-hole for the 5/16 crossbar.
Drilling and Chamfering
Step 17: Use the Ball-Turner to flat the ends of the crossbar.
Using the Ball-Tuner
Step 18: Now, place the screwdriver in the middle of the rod.
Placing the Screw Driver
Step 19: The next step is to test the tool.
Testing the Tool
Step 20: The last step is to clean and polish the lathe tool.
Things To Remember
- Make sure you remove the additional rust before drilling it.
