How to Build an Overarm Dust Collector for your Table Saw
Learn how to build an overarm dust collector to retrofit your table saw for improved dust collection. A lot of the dust generated by the table saw comes off the back of the blade and this shop made overarm collector helps capture that dust. This video is a follow up to my original "4 Table Saw Dust Collection Upgrades" video by popular request.
The table saw can be one of the biggest sources of dust in a wood shop if it isn't equipped with proper dust collection. Having dust collection below the table isn't enough since a lot of dust will come upwards off the back of the blade which goes into the air and lands all over everything in your shop. A lot of newer table saws have above the blade dust collection but older saws aren't equipped with it. This video shows how I built my overarm dust collector for my Delta contractors table saw and the materials that I used. The overarm dust collector is height adjustable to suit the thickness of the material that you are cutting. It can also be used with a cross cut sled which was one of my main design criteria. A lot of overarm dust collectors or over the blade dust collectors won't work with a cross cut sled which means you can't capture the dust from the top of the blade when you're using a sled. This overarm collector doesn't function as a guard since the front of the blade is still exposed but that is necessary to use the collector with the cross cut sled.
