    No hi-jacking intended just sharing what Jackie continually shares is helping me to learn how to do my very best of work. This also holds true for those who are asking me unrelated questions. Back to lathes the below video is but one that has helped me along the way. I think there might now be a " Using what you have on hand." question coming up.

    Here are those shafts installed in the vessel. They will Put the boat in the water next week. I will try to go out to San Jac Marine and take some pictures if I can.

    Jackie do you also do the shaft installations. Reason I ask is it appears all of your prior work could easily be damaged.

    The shipyard does the installation. They are well trained on how it’s done.

    They know there are no second chances. You do it right. The first. Period.

    Thank you for the clarification Jackie I was wondering at what point the liability for your own services ended and at what point someone else's then came into play.

    Louis, our liability ends at delivery.

    Keep in mind, these shafts, along with all rudder post, steering systems, and other critical items come under rigorous inspection before they ever leave our shop.

    It starts with the material, then the prep of the shafts, the welding procedure, the final non destructive testing, and the overall quality of the machine work, including not only the straightness of the shaft but also the fit of the Propeller and Coupling.

    So they sling them down into the hold, rig them in the hold area and run them out?

    Al, on vessels that have a permanent flange forged onto the coupling end of the shaft instead of a removable coupling, that is how the propeller shaft is installed. Large ships are an example.

    These shafts are installed from the outside. The shaft is supported by a crane and chainfalls hung from pad eyes welded to the bottom of the boat. The shaft is simply fed through the bearings. Of course, care must be taken to keep things balanced and avoid binding. To aid in the shafts slipping through the water lubricated bearings, most ‘yards coat the surfaces with dish washing detergent, which is slick and biodegradable.

    After the shaft is in place, the coupling is installed inside.

    Very much so Al and one can learn allot from what Jackie shares. Unlike CNC machining it's all hands on and as Jackie his employees are extremely talented.
