Give it a "motorectomy" --- just unbolt the motor. If there is no top to the treadle irons, just buy a good thick piece of wood, have someone router out the right shape for the machine, bolt the wood to the irons, and sit the machine down in. Should work. That's exactly what DH and I are in the process of doing for one of my old machines that didn't have cabinet or irons.
Be sure you put up pics. We like to see these resurrections!!
