Ok for you Rocketeer folks, are any of you having trouble with the cams wearing out? I use my 503a Rocketeer all the time for decorative stitches on my little Patchabilities. I use mostly the #8 cam, which is now slipping and messing up sometimes. I did some research and the only thing people complained about with those machines were the cams. The people who bought them loved the machines because they are all metal, well-made machines, but couldn't understand why Singer made such a nice machine then used plastic to make the cams. The cams wear out! Has anyone tried filing off the rough edges on those cams to see if they will have more life. Now I am a little concerned about getting a 319W -it uses cams too. The top hat cams are easy to find, not sure about the flat cams of the 319w?
