Get my son to re-wire it. I have my old Elna, and I didn't like the knee control, so years ago, he got a foot control and re-wired the machine for it. It was my first good electric machine and I still have it and will not part with it until I depart. Had to get a bank loan to buy it, way back when.
Guess I should tell you, son will not be doing another such as he is getting close to retirement and is on a 3yr. job right now.
