Well people, here is the manometer installed and operating, (again), with the tung oil applied, but not polished up. Figure most people are tuning out for the season, and might want to see it before moving on. It still needs a little polishing and waxing, so the sheen will be a little better once I take it out of service. Here we are the beginning of April, and the 111 is idling along nicely on TSC nut. Only a couple bags left, so the end is near.
So I learned a few things, but am satisfied with the final product. There are a few elements that I would do differently, but I think the scale is OK, for the size of the gauge. Now, the interesting part will be for the unknowing, how many visitors will recognize it's not a clock?
Hope some of you enjoyed the journey, and might also have learned a few things from this thread. Maybe someone will tackle a similar project, and improve on this design. I look forward to it. Thanks for following along. OFN.
