How To Flatten Aluminum Table Saw Top?

You may have heard various things about flattening an aluminum table saw top. However, not all of them are effective. In addition, some methods may end up damaging your table saw instead of fixing the issue. So, let’s take a look at the most effective options you can use for your aluminum table saw top.

Belt Sander

One common solution people often go for is a belt sander or a disc grinder. If you are using the right way to sand your table saw top, there’s no reason why you shouldn’t get a perfect and flat table top.

What is the right way, and what is the wrong one? The first thing to do here is to use 100-grit sandpaper in the beginning. It makes the process easier and also more effective. Once you’re done flattening the coarse top with 100-grit sandpaper, move to finer ones like 150-grit or 200-grit.

You have to be patient with the procedure and careful too. For instance, if you hold the belt sander in one place for too long, you will scorch the table top instead of fixing it. There will be dust generated from the procedure, so make sure that you’re doing it in a well-ventilated area.

Last of all, take care of the heat your belt sander is generating. It’s important not only to keep yourself safe but also to protect the table saw from damage.

Flap Sanding Disc

By attaching a flap sanding disc to a power drill, you can easily get an effective metal shaping tool. As long as you stick to 100-grit sandpaper when using the tool for your table saw top, you can get surprisingly good results with this method.

Sandblaster

You must be wondering why a powerful tool like the sandblaster is on this list. It may not be the most common tool people have in their homes, but it can be made available. What I am trying to say is that you can rent this tool from any rental shop.

Using 80-grit paper will get you the perfect finish you want. Nonetheless, if you think that the table saw top is more damaged than you anticipated, you can always utilize steel wool to smoothen the top before running the sandblaster over it.

As for uneven edges and other damages, try upgrading the paper to 100-grit, and all your issues will be resolved.

Ball Peen Hammer

If your table saw top is suffering from dents, the perfect way is to use a simple ball peen hammer. The method is exactly what you’re picturing in your mind. However, you will have to use some kind of padding on the aluminum table top before hammering your way out of unevenness.

In simpler words, use wood blocks on top of the dented area and use the hammer to flatten the area. You have to be careful about the force you are using. Otherwise, you will end up denting the tabletop in the opposite direction.

Sandpaper

The simplest way to even your aluminum table top is to use sandpaper. Larger areas might be more tedious to flatten when you’re using sandpaper to manually flatten your table saw top. However, if the unevenness is in smaller areas, this can be the easiest and, most importantly, cheapest method of all.

Be careful when doing the task, and don’t rub too harshly. Protect yourself using appropriate safety gear to avoid injury. You can also check my article on how to fix an unsquare fence on a table saw if you are interested.

Safety Tips

  • When you’re fixing your uneven table saw top, always find a well-ventilated area to work in. It’s best to do this task outdoors.
  • Keep all flammable things at a safe distance when you’re dealing with rust.
  • Use your gloves, earplugs or earmuffs, goggles, and a mask when you’re using a power tool to fix the tabletop.
  • Make sure you are entirely comfortable with the tool you are using.
  • If you are not confident with doing the task, don’t do it. You can always get your table saw serviced at a tool shop. Or better yet, invest in a new and advanced table saw. You can check my article on the most quiet table saw if that’s what you are interested in.
