Vacuum Upgrade – CNC

I finally got around to stage two of the vacuum system for the CNC machine.

First I built an articulating arm for the vac exhaust. I used nothing but scrap wood. Well, except for the knobs and bolts of course.

Articulating Arm

Unfortunately the exhaust is a bit too powerful, the suction doesn’t quite keep up and some dust is being blown back out the front.

I had been thinking about building a baffle for the vacuum’s exhaust anyway with the hope that it would cut the noise level more. Perhaps it will also cut the exhaust speed enough to create a negative airflow from the front to the back.

Well, maybe next weekend.
