About a year ago, I modified my ridgid contractor saw to a workstation setup with lots of storage and some other features like a down draft table and integrated dust collection. I didn’t want to spend a whole lot extra at the time to tackle the dust collection above the table so I modified the stock blade guard and hooked up a 2.5” hose to a vacuum which is plugged into a tool actuated power switch. Air is pulled through an overarm type setup that can fold down behind the saw when not needed. The vacuum provides some collection but there is not enough air volume to efficiently collect all particulate which gets beyond the shroud. The splitter has to be removed when doing dadoes and rabbets so collection is sub par during these types of cuts. Over the past few months I have been trying to size up a good solution to this problem.
I like the overarm solution but it limits the cross cutting abilities on my saw. The only way to improve this would be to make the overarm fold down behind as my current setup. I am not particularly fond of the factory splitter and it is a pain to take off everytime I need to do dadoes and rabbets. This screams out “over head dust collection” but there is an issue getting back to my DC main duct without the overarm. So I will do both. An overhead shroud and an overarm duct. More to follow….
