Gerhard, my book on restoring antique firearms warns against oiling woodscrews so they will go in more easily, saying that the oil makes the wood expand and grip the screws so you can't get them out again. If that's true, some sort of impervious layer between the oilite bush and the surrounding wood seems a good idea. Andy |

Gerhard I, myself I think that a sealed bearing would be better with the wood. Knowing how oil changes the look of the wood. And the bearing on that app. will never wear out. Good looking build. Nelson Collar |

Hi and thanks for the replays John -I seem to remember that was what you said on the RT job that your doing Nelson- I have a few spare so I ll make them disposable??? ( that is if they ever wear out) John and Andy - I was Worried that any acidity in the wood may couse problems, my plan is the seal the inside surfuces with a layer of set super glue - this leaves and acrylic layer that seals the wood permanently then just to seal the outside with raw linseed oil like the flywheel. I dont think the packing will get into the sealed surface. Wating for the Man flu to leave me alone so I can get back to the project. Gerhard |

just catching up with this build I like your stile there looks beautiful cheers Graham |

Hi Gerhard, I suspect John didn't want the thick grease in the oilite bearings washed out with cutting oil. What he said about tape, and also your plan to seal the outside of them, and the inside of the wood will probably be fine, and by filling the rest of the wood with boiled linseed oil, it won't want to leach out the oil in the bushings either. Most electric motors don't use live bearings, but oilite bushings, but put Gitts cups so ten years down the road, you can replace the oil which doesn't last forever. I have replaced many worn out oilite bushings in my life, and they have been the exact cause of the need for repair work each time. At the same time, if you were building a full sized engine with real wood bearings, you'd put cups on it to put lard in, so the heat of the bearings would melt it, and keep everything lubricated, so the cups would look right in place. I've had to locktite or solder oilite bushings someplace they wanted to leave, and had to wash them dry first, and then replace the grease with oil, and they soak it up just like sponges. That said, I have no doubt what ever you choose for a solution will work out fine, as it probably would if you had just bored the wood and used wood bearings. Now I'm just waiting for your next installment, looking to see the engine come into being. :poke: regards, mad jack |
