firelass77,
a word early on gives me considerable pause. Strip. If you truly want to strip and refurb you are in for a huge project. Cleaning and oiling will do great things to this machine. If you think a treadle machine takes a lot of space, you won't believe how much space it will take once it is separated into bits and stored in boxes. Also be aware that if you do a massive refurb on the head and the cabinet it will be hard to let it go after you have invested so much of yourself into it. That said, Its your machine, enjoy it as you will.
Pleasant memories of Edinbugh flowed into my head this a.m. A few days later I was in Pitlocery. Knocked on a door to tell folks of their chimney fire Laughed afterwards that I had traveled from Kansas USA to give them that information.
