Hi Rocsew,
Thanks for the info on the pulley wheel. Yes, its a bit hard, and its good to know where to get more parts for such an old machine.
Yes, we have a log house, from 1872...I am in the process of renovating it, so eventually the logs will be cleaner than in the picture and they will have mortar chinking in between them again. The log house is awesome for "thermal mass", meaning that the logs have such mass that they hold heat (or cold) a long time, and thus the temperature does not change fast. If I open the windows on cool summer nights and close them in the morning, the house stays cool all day, even during the hot daytime. No air conditioner needed.
Thanks for the help with the sewing machine.
