Vacuum Manifold welded up assembly

Hi, The other day I took my camera to work, so I could shoot some new pictures, of things we make, to put up on our companies web page. This is just one of the many products or parts we machine up for our customers. This is a Vacuum manifold,we made up. I machined the turned parts on a CNC lathe,the 2 flanges, and the main body. Then my friend Joe, machined up the main body,making the center portion square,with places for the other flanges to be welded in, and the part is complete.
  notice the turned parts, and how fine the finish is.. almost like a mirror. this is so they can get a positive Vac seal, with no leaks.
thought you'd like to see what I make during the week...
