Hello, Bezzer here just joined. I do love vintage machines and working on them. I have roughly 20 in the basement that i am going to restore. I sell machines here and there and just picked up my first service job. singer 500a. I have a service manual and just going checking things out and light cleaning. I saw somewheres that you should not run machine without 0 cam. Havent ran it yet but it does not have any cams with it. Customer wants me to get some for it. I am watching an accessory kit on ebay but other than that not sure where to get. Look forward to communicating with fellow enthusiast and sharing my victories and mistakes both for learning purposes for all. Not sure how to post things yet just responding to your post at this time.
