This is fine, but the mainsprings must be wound enough to provide sufficient power. Newcomers to antique phonographs will often hesitate to wind the mainsprings too much. Once you’re confident that your spring motor can be used without damaging it, winding the mainsprings is necessary. Important Note: a phonograph spring motor should never be disassembled until after the mainsprings have been allowed to completely run down! In all cases, know your limits (we all have them) and seek advice or assistance with jobs that are beyond your present skill set. This is a job best left to the experienced. Occasionally the problem is bad enough that the mainspring(s) will need to be disassembled, cleaned, regreased, and reassembled. Sometimes the repeated act of winding the mainsprings and allowing them to run down will redistribute the mainspring grease and the problem will resolve itself. If a “thumping” or “chugging” sound is heard as the motor runs, it means the mainspring grease has become hardened or thickened in spots.

(Paraffin-based products such as 3-In-One oil may become gummy and are not recommended). Minimally, all bearings and governor pads should be lubricated with sewing machine oil or other good quality lubricant. Unless it has recently been serviced, the mainspring grease and lighter gear lubricants have probably dried out. Your antique phonograph is probably powered by a spring motor.
