Okay, so I can stop worrying!
Thank you so much - I have really loved this process; reading the thread several times, ordering the stuff, reading the thread, again...
The cleaning part was almost miraculous - this 66 felt like 80 grit sandpaper, it was so covered in oil and lint. It was amazing to watch a shiny clean machine emerge from under it.
Thanks to your excellent method, I was able to save almost all of the decals.
And the cleaning of the working parts is just as beautiful - love, love, LOVE it! Thank you!
