    Questions for Necchi BU owners

    I'm looking at a Necchi BU and trying to justify spending the money. Lord knows I don't need another sewing machine. But ......... what's need got to do with it?

    Anyway, on the one I'm looking at the motor bracket is bolted to the head with two bolts in a horizontal line. There doesn't appear to be any way to adjust the motor for belt length. The machine has a rubber band belt on it.

    My questions are:
    >Is there belt adjustments I'm not seeing?
    > Do these normally use the rubber band belts?
    >Does yours use the rubber band belt or if not what belt number are your using?

    If the machine normally uses the rubber band belts I'll be reconsidering buying it.

    Joe, I can;t remember how my BU motor was mounted but I'm sure since it's an external motor there's some adjustment there. No, that stinkin belt is not original. I hate those things with a passion. People buy them because they are the cheapest belt you can get and you don't have to know the exact size you need.

    Which model of Necchi BU is it Joe?

    Probably not a BU Supernova. They have a cover over the belt and motor. If itís a BU Nova, the two holes are slotted for adjustment. Iím pretty sure that the BU Mira also has slotted holes under the two horizontal bolts.

    Good call CD. When someone just says "BU" I always think of the plain black original "BU" no name as that's what I had. I also see something on one of your pics that's at times another peeve of mine. I'm not fond of the lug belts unless they're the narrow v'd ones because I've found that they don't really fit right in the pulleys of my machines. Guess that's my automotive background.

    CD,

    The machine I'm looking at has the motor bracket like the black one in your second pic, but a different motor.
    I didn't see the adjustment slots until I lightened up and resized the pic.
    The pictures are not clear enough and the seller doesn't say which BU it is.


    Cari,
    Me too. I hate the cogged automotive and sewing machine belts. Like all things "New and Improved" they usually don't work like the originals.
    I always try to get the regular black V-Belts for the sewing machines, and solid belts for my vehicles.

    The black one is the BU Nova.

    I have a BU (non-Nova) and a BU Mira. The BU appears to be identical to CD's BU Nova.

    CD,

    Ok, if the Nova is black and the Supernova is that greyish color, what color is the Mira?

    Also is there any idiosyncrasies I should be aware of on these Necchi machines?

    You weren't asking me but the Mira is olive drab.

    Do Necchis have idiosyncrasies? Wow, what a loaded question! In a word, YES!!

    There is more than one “BU” model Necchi. It’s kind of like leaving off the first 3 numbers of a Kenmore, or the last two numbers of a Singer 15 isn’t it?

    Joe, the other photo that I posted is the BU Mira. Supernovas are green or pink.

    The only one that I can think of is on the Supernova. Good luck finding a new belt that will fit it.....”Regular” belts are too thick.

    Joe, if you can see the decal in the center of the bed that'll tell you which black model it is. The "VN' decal is a BU, the earlier machine. The "N" decal is a BU Nova, came just after the BU. Other than that they're basically the same machine.

    CD,

    OK, I'll keep that in mind.

    Cari,

    In the center of the bed is a circle with two "N"s in it. At least they look like Ns.

    Supernovas are also gray. That's my favorite version.

    Here's an idiosyncrasy: Miras have an attachment called the Wonder Wheel. Finding a ready-made replacement tire that is the proper size is impossible and so work-arounds have to be employed, i.e. they might be gaskets or other plumbing supplies, O-rings, etc. Finding all the cams can be difficult (and expensive) although I believe there are only 4 total. And you have to have the linking arms to attach to the levers of the machine.

    Here's my BU (not a Nova), just for reference:

    KRA,

    Thanks for the pic. The one I'm looking at is almost a twin to yours. I think I'll try for it.

    Might as well, I have an ALDENS Magic ZZ that's a clone to the Necchi BU.

    Go for it! They're nice machines. I prefer the Mira but the BU is a very solid machine.

    The early Necchi BU was a Nova for all practical purposes. At least the BU Nova is most like the one that had the old style “VN” (Vittoria Necchi) logo on the bed. The BU Nova also continued with the “U” serial numbers. Other models used an M or no letters at all.

    The ”BU” stands “Bobina Universale”.

    Cool then I think the one I'm looking at is a BU Nove. It has the VN in the circle on the bed and the serial # starts with a "U".

    OK, Imma goin for it.

    If it has the "VN" it's a BU, not a Nova. There is also a Nova custom deluxe that had the wonder wheel. There were 6 cams for it.

    Cari,

    It does indeed have the VN in the circle on the bed. And there is no wonder wheel gizmo on it. I've seen pics of those before.

    I've only seen most Necchis in pics too. I've had two BUs and finally got the kidlet to give me back my Lelia 510. Despite the little bit of nylon/plastic in it, (bobbin case cover, stitch length worm gear) it's a good strong machine. Quiet and smooth running.

    Hope there's no plastic bits in the one I'm looking at. If so I'll ........ I'm not sure what I'd do.

    No, I don't remember any in the BUs. My Lelia is a much later model, it's actually the second version of the 510 it has a different tension assembly than most. What I liked best about my BU was the light. It had two or three pivot points so you could twist and turn it to be right where you need it.

    Most of the made in Italy Necchi machines were pretty much all metal. The Lydia had a plastic camstack that was prone to cracking.

    Mark,
    There's also a plastic/nylon worm gear for adjusting stitch length in some of the later Supernovas. Same gear as my Lelia has. If you catch it before it breaks completely in half, some people have been successful at super gluing it back together. Luckily on my machine it's fine.
