Air Line Question

[myfinishingtouch]

I'm getting ready to add air lines to my garage. I've uploaded a picture of what I was going to install but now I'm not so sure. My question has to do with the area on the right side where I reverse direction. I had envisioned the pipe drooping down from left to right and then dropping 6 inches with two elbows and coming back to my take off. But as I'm thinking about it now, the pipe will probably droop and slope from left to right but after the two elbows I'm thinking the pipe should actually end up going upward -- I added a rectangle to show the two 90 elbows. I have a pipe bender. Should I bend the 6 " ****** and see if that will direct the return pipe downward?

I'd appreciate your thoughts.

Thanks,
Dave

It will give that much.

The thumbnail is small and tough for my eyes to see I can add most people don't bend black pipe, you can use a back to back 90° elbows and make a "Swing Joints" to get whatever the pitch is you need.

That's a great idea about the swing joint. I had to think about it for a minute but I get it. I was wondering how I was going to offset the lower pipe so I could do the vertical take off and using the swing joint should take care of that nicely.
Thanks,
Dave
