Wonders never cease! While looking for something else on eBay just now I stumbled upon this:
http://www.ebay.com/itm/FEATHERWEIGH...item2574d9564e
This is not an endorsement. I don't know this seller and have not tried this product, but it does seem as though it would be one more accessory that I might need. Has anyone else tried it?]]
Realizing that since eBay listings don't last forever, I decided I need to edit this to state that it is a listing for a crank attachment handmade by Scott Bishop to fit Featherweight 221 and 222 machine.
