Harrumph. The machine is only sixty years old, and already the drive belt is worn out.
When I wanted to file the receipt, I had to create a new folder.
$5.99 for the belt, $99 for knowing what to replace.
And for cleaning and adjusting everything. It runs better than it has in years; I presume that the belt started slipping so gradually that I didn't notice until it wouldn't sew at all.
