Just bought a Singer "lunchbox" machine that seems to work fine (shuttle bobbin type). Although I have not actually sewn anything on it yet, everything turns, goes up and down, and lights. My question is about the box itself. The base of the "lunchbox" was basically gone. We took the machine out of the base and the rest of the pieces fell out. The sides are still intact. My DH can make a new bottom easily enough but it looks like it was inset in some groves before the box sides were actually put together. Wondered if any of you DIYers would have any ideas on how to fix this properly? Have not looked up the serial number yet but will soon. Thanks!
