Timing and Mechanical Repairs

When the needle and hook stop meeting at the right moment, no amount of rethreading will save the stitch. This section handles the mechanical heart of the machine: hook timing, needle bar height, feed dogs that stop rising, handwheels that lock up, belts, motors, and foot pedals. These repairs sound intimidating, but many are a screwdriver and a careful eye away from done. Each guide shows what the part does, how to confirm it is actually the fault, and the step-by-step adjustment with the checks that prove you got it right. You will also learn which timing jobs are sensible at home and which ones are genuinely worth a technician bench.
