I've never seen anything like this. Once you have her up and running you have to do us a stitch sampler. That is if your guard kitty lets you near her newly acquired machine

Stitchit123,

That is my plan. With all the other machines it takes a ½ to 1 ½ 9x11" felt pieces to do the sample stitches. With this one I'll bet it takes 2 to 3 pieces. It should be fun.

And Pollyanna will cooperate I'm sure.

I have this machine sitting in my upstairs closet. Got it out a few months ago to run it. It is still working but noticed the numbers on the digital panel are not showing up as they should. Bought mine new when they first came out and digital panel went out. Still under warrenty, had it replaced. It does growl and the fan runs all the time.

Sorry to hijack this thread, but I have a real early Necchi (BC) and I am looking for some bobbins. anyone know a source?

Liz,

The digital panel is still available here: { http://www.searspartsdirect.com/part...&prst=&shdMod= }

Steve,
I don't know where to get those Necchi BC bobbins. Maybe Candace or Mizkaki or ArcaicArcaine (?)

Is it?? I have not used it for serious sewing in 20 years because it wants to 'eat' the fabric. Wanted to sell it but DH wanted me to keep it. I do try to get it out of the closet and make sure it is still running.
Good luck with yours.

Liz,

Thanks. I'm going to pull the motor and go through it today. Hopefully I can fix it's growling and make it go zoom zoom. If I can then I'll see what else the machine might need.

Motor Diagnosis, Part I:

I took the Sensor Sew to my basement work area and took the bottom and right end panel off.

There was a myriad of wireds around the motor:


Then I stood the machine on it's left end and removed the motor. It was held in by two hex head screws on the pulley end and a plastic peg on the fan end:


What I found when the motor was out was that there was a lot 1/16" or more of end play to the armature, and the brushes did not make full and proper contact with the commutator.
The bushings the armature shaft passed through were loose in the motor frame.
So I decided to disassemble it to try to fix it.

Ooops, bad idea.
I determined that the belt pulley and the fan had to come off. They are plastic and I didn't want to break them, so I tried to tap gently on the roll pin holding the belt pulley on. (Blue arrow)
I found out the hard way the motor frame was made from cheap, cheap, cheap, pot metal. Not even aluminum, but junk pot metal.
After a couple of gentle taps the frame broke at the bushing area and where it contacts the coil.
(Red arrows)


So, although I'm "pretty sure" the motor was worn out, it's busted now.

I guess I start hunting for a new one. I really don't want to chance a used one unless it's dirt cheep.

To Be Continued ....

You didn't do that damage with a couple gentle taps. I believe, from looking at it, it was already cracked or very stressed. Look at the frame under the big break - where the stud comes up - there are cracks all over the place.
I'm sure you will find a motor. Cost might be an issue but it will depend on how collectible the machine is whether or not you get raped on the price.

Looks to me like it was already in the broken stage when you got it and that is why the motor was sounding so growly. I have never seen a machine like that one. Interesting.
