I have a craftsman sliding miter saw that makes a ton of dust. I have attached a 5.5 hp shopvac to the port above the blade. It really doesn't do anything and the bag thingy put on collects nearly nothing. I have seen on this site people who have made an enclosure type thing with a hole in the back for the dust collection hose. Just wondering how well these work. Also, I didn't find an answer to whether a shop vac will work well. A large dust collection system just isn't in the budget now. Thatnks for any help.
