This serious is powerful In clarity! Wow! The idea of loosening and protecting the attachment screws is EXCELLENT! 👏

[@andveryginger]

Thank you so much for these videos! Checking the motor was the most intimidating part of restoration for me, despite having some experience with wiring and soldering. Even still, I did not remove the worm gear and commutator. I simply used a flashlight to check as much as I could, cleaned what I could reach, and sealed it back up. You make it look easy! After seeing this, I might attempt a more in-depth cleaning at some point in the future. For now, got it together and troubleshooting a sluggish foot pedal (a replacement worked fine with the motor, so I know the issue is with the pedal), and some skipped stitches. Looking forward to seeing more, and learning more about how to do better work on the next one!

When discussing the screws on the worm drive gear itself, for the *201-2” the screws are NOT IDENTICAL”. One screw is longer than the other. Match the LONGER screw to the notch in the armature. In contrast, the shorter screw is a secondary set screw. 😀 Lastly, the END TIP of the armature shaft (motor side) has a MARKING to show the notch of the spindle.

This series is amazing! Cannot wait for parts 9 and 10 as I am restoring the same machine currently . Can you please add how to disconnect the electrical parts from the machine?

i understand cleaning up the commutator but i do not understand why you would sand the iron parts of the rotor?

[@behrensb1]

Do you still like the tri flow greaase? Another Singer expert on youtube says its too thick, not to use on sewing machines, and recommends Sew Retro grease. Do you recommend cleaning the windings with an electronic cleaner spray? Thanks for any advice!

Thank you for showing the video. I just bought a 15-91. The motor was slow and started to make smoke. Open it up and the motor brush was broken inside. Trying to dig inside without taking a parts. But the pieces of the brush is still inside. What is the best way to clean it up?

[@angelatamborra2976]

Thank you for this amazing video's!! I'm in the process of restoring my Singer 15-91 sewing machine. This is a first for me for I've never restored a sewing machine before. When removing the shaft is there suppose to be a thin fiber washer on it? I don't see one on the shaft or on the bearing and I read on a blog that there should be one. Please help!

[@caitkistner4643]

How much of a difference will it be for a belted motor? I have a 15-90. I cannot find video #9 &#10, are they still in production?

[@vintagesingersewingmachine6320]

Hello Everyone ! What do you think about the computer generated voice ? I think it might turn some viewers off !

[@andveryginger]

The computer generated voice is certainly better than some other generated voices I've heard -- better natural pronunciation, and a bit more natural pacing and flow. I think, were it not, it would be much more of a turn off. In this case, it works well enough, and is clear enough to narrate what you're doing on screen.

[@Countrycharm17]

I'm so grateful I found your videos! I just purchased a 15-91 in a beautiful queen anne cabinet with bench. Shes in great condition except for a pretty deep scratch near the singer logo. 😔 I'm a jeweler, so I've been using my flex shaft and an ultrasonic to get the job done. Trust me, your videos are the BEST on KZbin on how to do this! I love the step by step process. Voice over is calming and encouraging, and the music compliments the narration and isn't too loud. THANK YOU SO MUCH! On the grease, what do you think of the Sew Retro Grease??

@@Countrycharm17 Hi Carol ! Thanks for the feedback. I can more accurately describe the actions by typing it out and thinking about it ! Sew Retro Grease is good to use too.

@@vintagesingersewingmachine6320 She's done and purring like a kitten! I couldn't have done it without your great videos. Her name is Rose, I named her after the lady who purchased her in 1947. I discovered the cabinet is Mahogony once I sanded the damaged top and refinished. Yay, I love her! Thanks again! Ps. I did use Sew Retro grease.

I have a singer sewing machine. I found it while cleaning up in my building that used to be my father in-laws. If interested I am selling it.

[@vintagesingersewingmachine6320]

Sorry for the late reply, It's been a hard year. I'n trying to finish up my projects without starting any new ones. You should't have any problems selling the machine.Thanks for watching !

You did not cover removing the motor gear grease wicks and clips and replacing the wicks, which become hard and non functional after 70 years.
