Those mice worked hard for that warm winter enclosure. I guess that is better than finding a live beehive or a live hornets nest in one.
Like Windy said and I alluded to earlier, Dempster’s (to me) are harder to work on than many other mass produced mills as it seems Dempster’s engineers were paid by the # of parts and or modifications.
Welcome Larry! The Dempster 12 was my first mill to resurrect. I didn't think it was difficult to restore, but had no previous experience so didn't know any better. You'll get it done. We're here to help.
