Bernina 730 record update
I went to the thrift store and found a Bernina record for $25. I saw the cam was cracked under the drive shaft arm but it had 10 feet and a hop to do small embroidery. I bought it. The repair of the cam and cleaning came to $160. The repairman told my husband it looked like it had never been used. But now I can't understand what that silver medal arm is for. I thought it was a knee lift outlet on the lower right on the front . It has an elbow in the unit. Any idea?
