The reason for the large piping is  over a long run ya gotta have a big pipe a small one just doesn't work well

 

Gives more volume too.  Just like air pressure more volume never hurts.  I like the you set-up.

Looks like a nice set up. What is your intended use? A vacuum chuck for your lathe?

I rather like my vacuum coupling.  It's an industrial bit o' kit I got for next to nuthin' on the flea bay.

I can go pretty fast   - - not mind you that I'd trust  vacuum with high RPMs.

I welded up a rig to go on the coupling to prevent it from spinning.  Apparently it is overkill and  unnecessary because the hose is stiff enough to  keep it still

here is a vid of the coupling  I took the fixture off that I had on it. the hose seems plenty  stiff enough to hold it under power

 The pipe thread into that aluminum disk is a left hand thread.  Hard to find a left hand pipe tap.  If you need one  I got one you can borrow so long as it won't be used  in steel.

I turned the aluminum disk so that it's double as a pulley for my slow speed rig.

Who We Are

Operation Ward 57 Challenge Coin Display Project

We are a woodworking community with an emphasis on sharing and learning the skilled craft of woodworking and all of its related disciplines. Our community is open to everyone who wishes to join us. We support our American veterans and active duty, being a veteran is not a prerequisite to join. Join us now!

Objective

Air Force Command Center Plaque

Of course just like most online woodworking communities we are centralized in the arts, crafts, and trades that are woodworking. But, we have another focus in our Patriot Woodworker community, we are the only woodworking community that was founded on our care and concern for our disabled veterans.

Volunteer

Patriot Woodworker Volunteers

The Patriot Woodworkers are an all volunteer community, from the staff and hosts who run our online woodworking community to the members who frequent our forums, you'll find volunteers in all of us. We are not on a payroll, unless you consider the spiritual rewards gained from volunteering, as compensation.

Education

Logging

One of the many projects we are working on is a wiki for our online community. A wiki is a great way for woodworkers and enthusiasts to share their knowledge to others, and to impart their knowledge for others to learn from, and utilize as well for their own benefit. We hope you'll consider being a wiki contributor.
