How to Use Power Rasps
Rasps are very helpful tools for power rasping and the procedure required to use these power rasps is very easy to go through. They look a lot like files, but they are rougher and are made for removing wood from surfaces. They are introduced in several shapes that include round, flat and half round. All you have to do is read this brief note on the process of dealing with a power rasp and you will realize how easy it actually is.
Step 1 – Safety First - Use the Handle
Your safety is the most important factor while using a rasp, so make sure you hold the handle first and let the rafting bit do its job. Sometimes a rasp may not have a handle; you may have to grasp it on the lower part of its teeth. Be careful. Make sure the rasp is clean and wiped with a damp cloth. If you see any kind of debris in the teeth use a rasp brush to clean it, but do not pull back on the brush, as this may turn the teeth of the brush brittle.
Step 2 – Brush the Teeth
Once you are done with the tang bit (which means rasping over the surface), make sure you brush your rasp’s teeth and leave it in its given handle so that it does not rust away. Also, make sure you hold the rasp by its tail or handle. Now place the rasp against the surface where you want the curve to form. Make sure you remove the sawdust from the rasp often with a brush. Blow or wipe the sawdust off the block so that you can see your progress.
Step 3 – Push in Desired Direction
Now that you have started using your rasp, push it in the desired direction and do not pull back at all. Always keep pushing the rasp in a single direction because that will keep the teeth sharper for longer durations and usage. Cleaning teeth can help keep the bristles sharp and better to use. Some rasps are used on electricity, which means you do not have to worry about the pressure. Make sure you switch off after usage.
Step 4 – Curve in
Make sure you use the rasp to make deeper and more prominent curves. A curved rasp is far better for more shallow curves, while a flat rasp is more efficient at making blunt cuts and slants. In order to know more, simply buy different kinds of rasps to find out about their curves and flats.
