Hi Glenn, newbie here and thanks very much for the instructions. I'm very keen to try this for my old singer handcrank that i've inherited, have cleaned it thoroughly with smo to the best that i can. I'm of course, terrified to ruin the machine, so forgive me asking silly questions. first, use denatured alchol and linseed (as per your earlier instructions above) and WORK ALL OVER THE MACHINE in circular motions, is that right? How many times and how long? is this process also known as french polishing? I tried to do research on youtube and there was no mention of linseed oil? I just want to be sure that i fully understand the whole process before embarking on it. Thanks very very much for your advice.
