Factors to Consider Before Buying Knife Belt Sander
Before pulling the trigger and buying a belt sander for knife forging, there are a few things you should consider. There are many options available, so you need to analyze what model will work best for you. You may even consider the best knife grinder for beginners if that is your preference.
Then, you can be confident that you are making the right decision. Keep in mind these belt sanders and different than straight-line sanders, which are more ideal for sanding tasks.
Dimensions & Weight
As you can see by the chart, knife belt sanders come in a variety of weights and dimensions. The best size for you will depend mainly on your projects and workspace.
For example, a lighter, small option would be best if you have limited space or if you plan on moving the machine regularly.
Otherwise, one of the more heavy-duty options will be your best bet. That’s especially true if you have large projects, and you will be using the machine for a prolonged amount of time. A big tool that’s great for this kind of job, is a top-rated bench sander.
The speed of the belt has little to do with the efficiency of the sander. Anything around 1,000 RPM is plenty to shape a knife. Of course, the faster the belt runs, the faster you will be able to remove material.
Most knife belt sanders come with a belt between one or two inches wide. It is recommended that for most knife making, a two-inch belt is ideal. This way, you can grind and sharpen your material. However, depending on the size of metal you are working with one-inch may do the job just as well.
The quality of the knife belt sanders on our list varies. For example, the more plastic found on a machine, the lower the quality it will have. Plastic wears down and breaks faster than metal.
If you want the highest quality of belt sander, look for machines that are primarily constructed in steel or cast-iron. These will outlast belt sanders that have several plastic, flimsy parts.
How to Use a Knife Belt Sander
A belt sander is relatively simple to use. As with most skills, the more you practice and experiment with different angles, speeds, and materials, the easier it will be.
Over time you will become more and more satisfied with your finished product. You will also feel more comfortable with the process.
Below is a reference to get you started with your new knife belt sander.
1. Plan Out Your Shape
Before you power up the sander, plan out the shape that you want your knife to be. You can even draw the shape roughly onto your metal. This is called profiling your knife.
2. Position The Material on the Table
It is easiest to keep your cuts level if you rest your metal on the small table in front of the belt at least until you get your basic shape worked out.
3. Power Up the Machine
Press the metal into the belt and follow the line that you drew before. Go into the belt at an angle. This will profile the knife much faster.
4. Sharpen Your Blade
When you start your project your sandpaper will be 80 grit. By the time you start sharpening and polishing you will move up to a 120 belt then finally a 220 belt.
Things to Keep in Mind
- Knifemaking using a belt sander is an acquired skill. You will learn by a lot of trial and error.
- Use a full-face mask to prevent metal shards from getting in your eyes and lungs.
