I have purchased a Singer sewing machine in a bentwood case. The wood case is not in the best of shape. In addition to some scratches there is a dime size hole in the case. I knew the case was damaged when i purchased it but felt the machine alone was worth the purchase price. I know I can purchase a better case for the machine but I would at least like to try to see if the damaged one can be repaired. My first thought is to use a wood filler, then sand and refinish it. Do any of you have any suggestions?
