Tuesday, February 2, 2016 A nice rainfall during the night left the outside sopping wet, and I spent the day in the shop working on my magneto. One important part of magneto assembly is adjusting the height of the magnets. There are sixteen magnets, and all thirty-two poles should be as nearly uniform in height as possible. When I had all of them bolted and screwed on the flywheel I measured and found that they varied from 1.724" to 1.744". A difference of .020" is too much. Some people adjust the height by shortening the spacers under the higher magnets. I decided to go the other way and put shims under the lower ones. I made the shims of .005" brass. I needed two shims under the spacers for the lowest magnets, and some weren't that low and took only one. And of course some were close enough to the same height that they didn't need any. When I had all the shims installed and all the bolts and screws tight, the heights varied from 1.737" to 1.744". If I wanted to get really nit-picky I could have added one more shim in a couple of places, but a difference of only .007" is more than good enough. The next step was balancing the flywheel. One of the tools I made last week was a mandrel for flywheel balancing. I found that the balancer is mighty sensitive. The flywheel with the magnets on it weighs over fifty pounds, and a little five gram magnet stuck on the outside is enough weight to turn it. I spent a long time sticking on and taking off those little balancing magnets and never did get the thing perfectly balanced. The idea is to be able to turn the wheel to any position, and it will stay there. The thing was still slightly out of balance when I went to town to buy celery and pay bills, so balancing is a job to be continued. |

Thursday, February 11, 2016 A little bit of shop work, some computer time, then a day outside. The shop work was painting a headlight adjusting screw for the touring car. It will bake overnight and I'll install it tomorrow. The computer time was the usual deleting of spam and checking the online forums and classified ads to see if anything I need or want is for sale. The outside work was splitting the pile of wood behind the shop and stacking it in the garage. A lot of the wood was knotty and a lot of it was rotten, so it broke into small chunks no good for stacking. That made a considerable pile which will go into boxes. I may not get it all boxed up in one day, but I hope I can get it done before the next rain. I have more than enough wood put away now to last the rest of this winter and spring and get a good start next fall. |

February 20, 2016 After checking two auctions in Winfield and finding absolutely nothing to keep me there, I took advantage of the warm day for some outdoor work. I cleared a shortcut between the branches of that Y in my woodlot road. Saturday is my eat-in-town evening, so I enjoyed a delicious repast at La Fiesta, then took in a movie. Risen is a well-made film based on the New Testament. It features good writing, with nice character development, convincing performances by the actors, and is well shot and directed. The previews shown with it were for a bombastic biblical epic and a religious-political polemic I will absolutely avoid. |

Taking advantage of one more unusually warm day in the sixties, today I worked on the new south road I started three weeks ago in the wood lot. I want to make it one large loop going down the west side, across the south end of the place, and back up the east side. I doubt that I'll finish the whole thing this year, but maybe I can do the west part and make a turnaround at the south end. Today's work was cutting off branches that were in the way, some of them fairly large. The pieces will be part of next year's firewood. This new satellite view shows the established road in yellow and the new extension I've cleared so far in green. The weather.com forecast shows cooler weather during the coming week, so I'll get back to indoor projects. I want to have at least one Model T ready to go when warm weather returns. |
