Bernina 217 6mm to 12mm zig zag

[AndreaIbis]

I recently bought a Bernina 217 6 mm zig zag. I saw a 6mm to 12mm zigzag conversion kit on a Bernina 217 sparenparts. Other people managed to convert. I open this post to share the experience and have suggestions if someone has already done it.

Very interesting! I´m wondering if this kit is still available and how many hundred € it will cost.

I'm also studying, I'm looking for someone who has already made this change

I found the kit available at Global, in practice they produce a car equal to the Bernina the Global zz217. I would like to understand if anyone has tried to make this modification to bring the machine to 12 mm I already have the offer and it is not so high but when I ask if the kit is compatible with the Bernina, they don't answer me.

I ordered the Bernina 217 conversion kit from 6mm to 12mm, from Global Parts in Holland. 

Ich habe den Umbausatz Bernina 217 von 6mm auf 12mm bei Global Parts in den Niederlanden bestellt.

Nach fast einem Jahr habe ich es endlich geschafft, alles zusammenzubauen und die ersten Tests durchzuführen. Es war gar nicht so einfach, ich bin schließlich kein Nähmaschinenmechaniker, aber sie funktioniert. Nur die maximale Zickzackstichlänge von 9–10 mm ist nicht wie erwartet (statt 12 mm). Vielleicht muss man da etwas einstellen, aber ich komme im Moment nicht drauf. Es gab ein kleines Kompatibilitätsproblem mit den Zahnrädern und den Schrägverzahnungen, da sie nicht richtig in das vorhandene Zahnrad passten. Mit etwas Schmirgelpaste habe ich die Maschine ein bisschen gedreht, und dann hat es geklappt.

After almost a year, I finally managed to assemble everything and do the first tests. It wasn't easy at all; after all, I'm no sewing machine mechanic, but it works. Only the maximum zigzag stitch length of 9–10 mm isn't as expected (instead of 12 mm). Perhaps something needs adjusting, but I can't figure it out at the moment. There was a minor compatibility issue with the gears and the helical gears, as they didn't fit properly into the existing gear. I used some emery paste to rotate the machine a little, and then it worked.

Ich habe auch noch dieses rot eingekreiste Teil übrig, von dem ich nicht weiß, wofür es ist und wo ich es hinstellen soll.

I also have this part circled in red left over, which I don't know what it's for or where to put.
