welcome to the board and a fascinating new interest! I know many members have disassembled their machines for repaint so it can be done, the machines were designed for home upkeep unlike modern machines we don't dare touch
There was a recent thread about a man who pulled a vintage machine out of a pond or shore and showed him disassembling and reassembling it, very interesting. Acquainted me with the tools he used and the way he kept the parts organized.
Again, welcome, and well done on the purchase price!
