Well, I've done most things a normal operator needs to do, change bobbins, needles, re-thread, dust. I have a roller problem. I made a mark where the machine seems to hang It'll do that in 4 places every time I make a pass. Same place each time. I've already got an appointment with the dealer . . . but not until next Saturday. Meanwhile, I have time off, a stack of tops, batting and backing, and a wonkey LAQ. No laughing matter here. Think I'll go clean the basement for a while.
