Welcome to the site!  

 Sounds like you got into the hobby in a hurry.  I am not familiar with the Jacobs machine but I am sure someone will ring in.  This is a great forum and there are a lot of helpful people here.  Pictures of those machines when you get a chance would be nice!  Also pictures of the specific issue with the Jacobs will probably help anyone who knows about the machine.
