Steampunk - The lubrication manifold Jigsaw Puzzle

This is the lubrication mixing manifold, it is perhaps the most important part of the machine. Using only a single operator, it allows a user to select a special blend of lubrication so each part of the machine works properly. You can send oil to different parts of many machines at once if you set the valves up ahead of time. Naturally this system has a way to reverse the process so the old oil can be removed and then again replaced. It's truly a modern invention of this time. Everything is regulated so there is little to no guess work involved. In the past it would have taken a small team hours to complete the task, but all of that changed with this invention.
