  • If only they had told me what they were doing......

    A couple years ago, I was asked to build two aluminum frames to "support some ductwork". I was given a sketch, and the job went without a hitch. End of story...not quite.

    Last week, the new doctor in the Vet Tech program asked me if I could raise two stainless steel enclosures hanging from the ceiling in the operating room.



    The bottom is only 66 inches off the floor. People are always bumping into them, or having to look around them.

    Looking inside, I found the two frames I had built. Turns out they bought the wrong length enclosure, and they didn't want to wait for a replacement. If I had known, I could have shortened them, and made the frames to fit back then. But they never asked.

    The enclosures have a quad electrical outlet, an oxygen and a nitrous oxide quick disconnect, and a waste anesthesia gas suction line. Everything except the pvc is flexible.



    The frames are secured to the ceiling with threaded rods and self-locking nuts. Getting into the overhead to hold the upper end of the threaded rods was a real problem, so the upper part of the frame had to stay in place.



    I developed a plan to remove the SST enclosure, shorten the frame in place, then put it all back together. The first thing I did (not part of the plan, though) was...



    Yep, it's definitely too low.

    After getting everything out of the way, I cut a section out of two legs of the frame, and installed temporary supports.



    Then I cut the other two legs, installed joiners on the upper ends, removed the temporary supports, lifted the lower part of the frame into position, and secured it with clamps.



    Now it's just a matter of riveting the joiners on all four legs, reinstalling the plumbing and electrical pieces, and shortening and reinstalling the SST parts.

    What could have been taken care of in a couple hours is going to take three or four days to fix now.

    Yikes, I just noticed the clock. Now you know how slow I am.

      I can see you raising it up, but then how do those short nurses
      plug into the electrical outlet and more important, the oxy line ?

          OUCH!
          May I suggest turning a safety edge around the bottom of the boxes too...
          At least you had some nitrous on hand to ease the pain...
          Cheers,

            I only raised it 12 inches. I had the Doc and some students do a "reach test" to where the outlets would be, and they all approved of the new location.

              Given your forum name I think a remote controlled raise/lower would be in order.

                  Si... that is best. Wear it loose, so you get some warning of the threatened damage before it happens.

                    It's a ballace, trust me.
                    They rarely give you all the needed information to do a bang-up job.

                    I have learned to fish it out of them. BUT this was a hard learn.
                    I use to scare off some good work going too far with open questioning.

                    I think folks figure they called you for answers not questions.

                        I got all the riveting done, cut 12" off the enclosure, and got it back on the frame. You can see the splices here:



                        The fit to the ceiling is very good, and I was able to reuse all the holes in the lower part of the frame.



                        Just a little more to do, and I can start on the second one. I hope it goes as well as this one.

                          Nice job!
                          Agree 100% on the subject "If only they had told me what they were doing......" No idea how often I've had jobs where 'what they wanted' was at odds with what they were trying to do.

                            66 inches from the floor. I don't see the problem. Plenty of room for folks like me

                            Were the splices made from the bits of frame you shortened?

                            Nice job, doesn't look like it was modified from the outside.

                              I cut the two temporary pieces and the eight splices beforehand so I could deburr the ends in the shop. The pieces I cut out will be used by the kids for welding practice.

                              Thursday I got the second one taken apart, and I have the legs shortened and splices installed on the frame. I'll probably finish up Monday.
