I just setup my new vacuum chuck system. I’m using a refrigerant evacuation pump as seen in the photo below:
When the vacuum is at less than full pressure, there is a fine mist that comes out of the output side. The mist goes away if the vacuum is at full. I’m wondering what the mist is – is it just water vapor, or pump oil? It doesn’t feel oily or damp and has no odor.
The first chuck I threw together worked like a dream. I turned a platter, and then reversed it and took the foot completely off. Looks like it will also be really handy for off center turning.
