Dust Prevention With Your Table Saw

If your fence piece has been tuned properly it should be parallel to the blade. This will make your wood contact the blade only on the front saw teeth. For an ideal cut, the kerf walls should not be cut by the rear blade, instead they should be barely brushed.

It is impossible for shavings to be generated by the front of the blade and flung at you. This would mean they go through gullets three fourths of the way of the circuit, going 125mph and then jump at you in their last few seconds.

Debris that comes at your face is generated in a completely different way. This would be the rear teeth cutting into your wood, which is definitely not the way your saw is supposed to operate. Instead of choosing a dust hood, you need to pay attention to the message your saw is trying to convey.

This message is that your blade, fence, or both are not in correct alignment. This is something that needs immediate correction. This is a bigger problem than waste, inefficiency, ugly marks, or even a face full of scraps.

Kickback can be generated by even small misalignment of the blade or fence. Keeping in mind that kickback is the catalyst for many tablesaw injuries, making sure it doesn’t happen should be a big priority.

Ensure that your blade alignment is precisely parallel with your miter slots. After this align your rip fence also parallel with the slots. Offset it by a few thousandths of an inch towards the table rear, this is as much as two pieces of regular paper. This ensures you can’t make a mistake in the opposite directions and cause your fence and blade to pinch your stock.

When this is done correctly, the only sawdust coming at you will be from very solid pieces of wood. These pieces will pinch or spread with a lot of force when being cut. If you are still getting pieces like this, you are better off cutting them on a bandsaw. This is safer because kickback will not be an issue with this change in saw types.


DO YOU HAVE a woodworking project or tip that you would like to submit to WooDesigner and get it added to our site? Then go to the contact tab below OR at the top of this page and let me know. Just make sure you are able to give us step by step instructions on it, as well as images as you see here, and we will put it on this site just like you have read on this page! As long as it is clear and concise like you just saw, it will go up. Your name will be credited to the project, as where you live. (Please include that.) Also include the type of lumber you use for the design. We look forward to hearing from you! (Take note that the tip and images and instructions have to become ours. I do hate that so much but in today’s society so many will sue, and yes, you can sue for a lot of money over images.) The tips will need to include YOUR IMAGES that you take. They can’t be images from somewhere online. Remember, we have to go through these images and if they aren’t your own, we will not be able to use them. This is illegal and it won’t be tolerated and you will be banned from this community by being blocked. We can get sued for this, and just one bad apple can ruin our community.
