Question about frozen Singer 15-88
You have all been so helpful with my machine that I thought I'd ask a question for Sis about her 15-88. The upper works seem to be frozen. The balance wheel turns freely, but the needle bar and the thread take-up lever do not move. The needle bar and thread take-up lever do not move independently (by hand) from the balance wheel. Any ideas? If the head is frozen, how should she loosen it?
