I find myself in this situation: I bought a used Sailrite Ultrafeed sewing machine, which came with a bunch of accessories, including a table with a Consew servo motor. The Ultrafeed is in a travel case, and I want it take it on boats. I also have a Kenmore machine from 1970, with a badly-damaged case. It would make more sense to transplant that head onto the table. The machine has the same dimensions as the Ultrafeed, so I just need a new drive belt.

The servo motor also has a needle synchronizer. Is there a practical way to attach that sensor to a domestic machine (that has a clutch)?
