Cheryl, I'd previously put together an extensive series on how to re-wire a potted motor here:
http://vssmb.blogspot.com/2012/01/co...ted-motor.html
It uses mostly still photographs rather than video, because a) shooting video of the extensive procedures covered would be prohibitively time-intensive, and b) with longer, more involved stuff like re-wiring, I think still photographs might actually be better, so you can follow along at your own pace.
If there's enough demand I may one day attempt to video a re-wiring, but I'll likely have to acquire some specific types of lighting and a camera with a very shallow depth of focus, neither of which are in the budget right now.

Rain, Thank you for posting this excellent tutorial! I wish you had this video posted 2 years ago when I started collecting. I had to learn the hard way; and even then, I didn't think about marking the shafts with the dots. I loved the"x ray" section of the tute, very well done. I enjoy you helpful post. I was through following your tute on removing the 201 bobbin case to clean that area up, I was able to do this simple task. Thanks!!!!

Muv, please disregard steps 1, 3 and 4 from message #7 in this thread, and just try step 2 when you have time. I'm messing around with a machine right now and I *think* I may have found what ails yours.

Rain,
I think you can save yourself the air fare. I have had fun with the screw driver this afternoon.
You will be pleased to hear that the 15K is now fixed. All it needed was oil on the shaft, and I feel a bit of a dimwit about not getting it sorted before now.
No joy with the Serata yet. It has nearly a century of black muck welding the balance wheel to the shaft so I can't get it off to clean and oil it. I'm inclined just to leave it as it is. What is interesting though is that there is a lubrication hole in the balance wheel to take the oil straight to the right place, whereas with Singers you have to take the wheel off if you want to reach that spot. Very clever, the Germans. One of these days I might do a video about pre-War German bobbin winders. They are in a class of their own.
Talking about clever Germans, I have two machines, the Little Vesta and a Frister and Rossmann transverse shuttle, that disconnect the motion with a much simpler mechanism, so you have no wretched stop motion screw to contend with. Want to see pics?

Suh-weet, Muv, that's a relief! About the 15K, I mean. I'd never heard of a Serata; I'd have guessed it was a small city car that gets excellent mileage.
German design and engineering is thoroughly astonishing. I learned this both at design school and while researching articles I've had to write for work, like this one I'll link to below. It will admittedly only be interesting to a minority of people, as it's about the industrial design of a German gas can--the "Jerry can"--from the 1930s:

In any case, Muv, would love to see pics.

Hello Rain, The Serata is the treadle on my "How to Treadle" video. It was manufactured by Bernhard Stoewer in Stettin. You will probably enjoy the website www.stoewer-museum.de
My husband has just walked in so I am showing him the jerry can article - it's just up his street.
I think I could start a whole new thread - Ingenious Features on Vintage German Machines. Interested?
