Vacuum Chuck Part 1: Air System

I've been meaning to put together a vacuum chuck for a while now, and finally had a project required it. I broke the video into two parts:

Part 1: Air System
Part 2: Vacuum Chuck Adapter

Below is the parts list to build this portion of the video:

Brass fittings:
2 x T's
2 x air compressor quick couplers
2 x barbed tube adapters
Bell valve
vacuum gauge
plastic tubing

The dust input to your vacuum pump isn't down on the floor where you put your pump, it's on the wall where you put the bypass valve or on your headstock when the bypass valve is closed. An inlined air filter would take care of both inputs.

Thank you! You are exactly correct that there is 'nothing' out there about the air system!

I Also need to know where I can buy the tube/bearing that is going through the headstock?

Nice setup, what size of a pump did you use?

[chadhartley]

Where do you get the bearing and seal fittings?

Excellent instructions. Would you consider using a lapel microphone? Your camera mike is insufficient to pick up your voice when you don't speak loudly and clearly. I dislike having to turn the volume up all the way to hear YouTube videos. Also, give the sizes of the fittings, etc. Standard for air is 1/4", but someone without experience would not know what size to buy.
