This is a project I have been working on for some time now but it still dose not work as well as I like it to. So I thought I ask for help… This miter saw station works using an old blower from a furnace to remove dust from the cutting area around the saw. It removes about 90% of the dust made when cutting. Furnace blower don’t work well for dust collection. They do not generate sufficient static pressure to get the velocity need to move material.
So how dose this work at all, that a good question. I have noticed that is much easier to blow dust around the shop than to suck it up. I have played around with this premise for some time. Many of you that have garage shop have opened the overhead door and used a leaf blower to clean out the shop in no time. This station utilities the intake and the exhaust of the blower. Just behind the saw are two intake ports that drop into two filter bags. At the sides and top are small hole that blow in and down from the exhaust. The idea was to push the dust down to the intake ports, making an air curtain that keep the dust from move out into the shop. Only a small amount of exhaust air is used.
I am hoping to get more the dust to stay in the the box put it is hard to see how the dust is moving within the hood.
I have also put a craftsman auto switch in to make the blower turn on when the saw starts up.
Let me know if you have any good “i deer s” that might help.
