Jigs are used to hold the lathe tool in place. With the help of a jig, you will be able to sharpen your bowl gouge with consistent bevel angles.
You should also try to get your hands on an angle finder. An angle finder helps you verify the angles that need to be sharpened. Couple the angle finder with a sharpening jig, and the sharpening process will run smoothly.
Lathe tool sharpening does not have to difficult if you have the right tools. Once you have got all your tools ready, it’s time to move on to the next part.
You need to know that the main tool that you are going to sharpen your lathe tool is the grinder. To use the grinder to sharpen your lathe tool, you need to first dress the grinder.
Now, what do I mean by dressing the grinder?
Well, chances are, that debris remains on the grinder from past sharpening operations. You want to remove that debris and prepare your grinder for the optimum sharpening of your lathe tool.
Dressing the grinder involves using a diamond sharpening tool. Scrub the grinding wheel’s outer edges with the diamond sharpening tools. This will remove any debris on the grinder.
Step-3: Get your angles right during grinding
Lathe tools operate best at specific angles. Finding the right angle is crucial if you want to sharpen your lathe tool right. Using an angle finder tool can help in this matter.
Step 4—Make Sure That There Is Proper Contact
Position the lathe tool at rest and proceed to move the lathe towards the grinder. Keep going. And stop when you reach the point where the tool makes contact with the wheel.
Watch out for one thing: At all times, you must ensure that there is minimal contact with the blade and the wheel. Otherwise, the sharpening process will go wrong.
Be extra cautious not to press too hard on the lathe tool. If too much pressure is applied from your end, there is a high probability that the blade will bounce.
Step 5—First Phase of Sharpening Lathe Tools
Grinding the lathe tool against the grinder can be divided into two main parts.
The lathe tool needs to be pushed gently against the grinding wheel. Special care must be taken to ensure that the lathe tool is not in contact with the wheel for more than 10 seconds.
You’ll see some sparks emerge during this time. Sway your lathe tool from side to side during this short interval. You are doing it right if sparks are produced during the process.
Step-6: The Second Part
You should do the 10-second sharpening procedure a few more times. And when you are satisfied with the sharpness attained on your lathe tool, dip the tool in a bowl of water. Cooling allows you to hold a tool for the remaining part of the sharpening process. Repeat the entire process for the opposite face of the lathe tool.
