It wasn't today but last week I fit a borrowed handcrank to the Singer 99 that Cari-in-Oly gave me this fall. Roserips loaned me the handcrank as a trial run to see how we liked it and for use at next year's fair here in Lewis County. It took about 15 minutes to swap out. The only bummer is the case's lid is lacking about 1/4" of clearing the crank. I'll probably just sew up a bag for the crank to live in while not in use instead of modifying the case. It would be easy enough to remove some wood from the inside of the lid but I just can't bring myself to make a permanent mod like that to a perfectly good cover.
