You all will be proud of me. The grub screw holes in my Singer 319 somehow stripped out when I removed the screws to take the machine out of the table I refinished. I bought a new thread tapping die at Lowes and made new threads in the holes and bought matching screws....not original of course, but it's in the table and works. Woohoo! I was kind of sweating this one and was worried I'd really mess it up. I gave my 319 a kerosene bath today which cleaned it up some what.
