Sanding is the final task of any woodworking project that needs to be done with the required cautiousness. We use the orbital sanders as it is handy and easy to use and offers a professional edge, after all the aesthetic look, touch, and feel of the surface comes, once the sanding has been done correctly.
An orbital sander is a square model that uses a quarter sheet of sandpaper and is also called a quarter-sheet sander, the best part being it does not require any unique material of sandpaper so whatever is stocked up, can be used for sanding. The orbital sanders are not an aggressive sander and hence not recommended to be used when a tremendous amount of material is to be removed; they are appropriate for fine work on the edges and tight corners.
The investment made in the best orbital sander is worth it because of the promising results if done correctly. This machine moves in a circular motion for giving a more elegant finishing touch to the masterpiece you want.
The working principle is very simple The pad of a random orbit sander moves in 2 ways: It wiggles in a tight orbital pattern while it rotates. This combined movement leaves a random pattern of scratches running in every direction, and overlapping. But when you sand the wrong way, you are going to prevent the sander from working properly. You’re going to receive visible scratches, frequently in the form of long, spiraling swirls.
The following steps to use orbital sanders will surely make it an effortless task for you, and you should not worry if you are an amateur because the process is super simple and you can be a professional in no time:
- The first step is to assure everything about the safety standards while working with sanding so, start with wearing a mask and transparent goggles which are meant for such kind of work to ensure that the dust particles do not enter your eyes or nose, which may cause irritation.
- Now clamp or secure the wooden piece that you wish to do sanding on, this prevents the wooden piece from unnecessary movement while sanding which may cause accidents like excess of shelving in a particular area
- Next up, set up a ventilation system that would collect the dust accumulated while working and dispose of it safely, this saves your time in collecting the stubborn sawdust after sanding.
- The next step is attaching sandpaper, choose the grit as per the requirement of the project. Coarse grits of 40 and 60 grains of sand are suitable for materials requiring heavy sanding. However, a coarse grit might leave marks on smooth boards which is much less than hand sanding. Finer grits 180 and 220 grains of sand leaves a smoother finish, but a longer time is required to achieve the desired results
- Once you finally select the appropriate sandpaper, fix it to the sander. Usually, sandpaper meant for being attached to an orbital sander comes with an adhesive back, which can be peeled and gently pasted on the pad. Or in specific models, these sandpapers are also attached with the help of few spring-loaded clips.
- Now before starting the sanding, let your machine run in its full potential power and speed before you start using it on the wooden piece, using it immediately would not give desired results
- While sanding, do not press against the material as it may cause marks or dent. You must gently move the sander on the entire area, evenly. This will ensure that you are sanding equal amounts from the sides.
- Finishing up: sand the edges of the material by hanging one-third of the sanding pad over the edges to achieve perfection, once you are satisfied with the sanding done, dust the remaining sawdust with the help of a brush or piece of cloth.
And then you are good to go with the area, now repeat the process with other areas, and voila, you have completed the meticulous task very quickly.
