Glenn, Hope I didn't mess up my machine. I started on it before I found your site here. I just acquired an old New Royal. She was rust fast and nothing would move. I sprayed it with WD 40. Got everything moving except can't get pressure foot off yet. It is rusted on. Did the WD 40 do any harm? Should I get your rust blaster and respry everything now? I don't know know what to do now. Cannot post pics tonight or I should say this morning considering the hour. LOL Wish I had found your site earlier. Any help will be appreciated. Thanks and blessings, Gragra
