My CNC 6040 requires a vacuum cleaner. I want to make a small bracket that will be connected to the spindle while using a clear plastic to keep it safe from dust. I will use it mainly with PCM or aluminum material. I will however use it for wood at in some occasions. I am yet to make up my mind on attaching mechanism details. In this case, I am not sure on the kind of vacuum to use. I have been thinking of using Karcher MV2 but I am not sure if it is good enough for this job. Its positive side is that it is cheap and small enough to fit below the table that I am currently building.
