Nettar II 518/16 Minor Repair help

[AzzA]

Hi there.
I just picked up a nice little Nettar 518/16 for a few dollars (couldnt pass it up). It's in terrific cosmetic condition. The glass is perfectly clear, and the shutter seems to work brilliant. Theres only one problem though.
The film wind-on is dissasembled. I found all the loose parts had been kept inside the film compartment, which is quite lucky. And I seem to have just about everything needed to put it back together except what I think was a very small screw on top. The issue i'm facing is that I dont know what order i have to reassemble it all, and if theres anything i'm actually missing (besides the tiny screw).
Does anyone know of some diagrams of the Nettar cameras? Something where I can see the assembly order of parts etc?
Or, if i posted up an image of what I have, could someone help guide me through it?
I really want to put a few rolls though this camera.
Cheers
🙂

Interesting theme ! I just did an Internet-search and came up with nill results. This must speak for the quality of the Signal Nettars. They obviously hardly need a repair in that area.
This Nettar also has a Double Exposure Prevention mechanism so there must also be a connection between this mechanism and the Winder knob.

Maybe you could ask forum-user FallisPhoto. He is a real folders expert.

Otherwise i shall see if i can open up my Signal Nettar one of these weeks.

Succes

If you can, post a photo of the parts. Most camera makers used similar assemblies. Often, a small arm on the film advance post resets the double-exposure prevention (the "signal").

Go ahead and post an image of what you have. I'll see if I can guide you through it.

Cheers guys. Really appreciate the help.
There are no signs at all of the camera being taken apart, so i'm still curious as to why the film advance assembly is in pieces.

This is an image of the parts I have. Would they assemble in an order like this?

I'm mainly having an issue with how the top part attaches. It seems like I cant push the winder knob onto the winder post enough if I have the "neat" side pointing up (as shown in photo). If thats the way it's definately meant to go, I assume that there might be a burr or piece of metal preventing me from pushing it on enough. I guess you cant really see it in the photo.

I'm also going to need to scout around for a screw small enough to hold it all together! Maybe I might be able to get one from an old unusued camera somewhere.
Thanks again for the help.

Thanks for the photos. Now we know what we are talking about !

I'm not sure if that black ring just above the axle belongs to this assembly. This may belong to another part of the Nettar. The extra height of that ring is possibly the main reason why you cannot fit the Winder Knob the normal way.

I'm sure about the fact that you will have to remove the topcover. The small ring with the 2 teeth belongs underneath there and is part of the Double Exposure Prevention mechanism.

 

[AzzA]

Thanks for the reply, much appreciated.

I'm thinking I might have a couple parts missing. I'm concerned about the ring with the 2 teeth. Inside the camera, the little latch it's meant to trigger is only quite small, and theres enough room for the teeth to miss it if the whole ring moves up a bit. I assume theres something that used to keep it inline with the latch so it'd work every time. Maybe a spring or some kind of spacer??

So frustrating, because I really want to shoot with this thing! 🙁

Hi AzzA,

Out of curiosity i started disassembling my Signal Nettar. Will take a couple of days but you can have a look at the first pictures by visiting my Flickr pages. Use the hyperlink at the bottom of this posting.

Cheers mate, will do 🙂


edit: I've already noticed a part i'm missing. On photo "06" theres a silver metal "spacer" that is part of the assembly(you can see the top of it through the hole in the top plate). That's what must keep the toothed ring down so it can reset the double exposure meter.
Also, can you confirm that theres just one screw holding the whole thing together? And does the shaft portrude almost all the way through the top knob?
Thanks again hanskerensky, your photos have already been a huge help.

The hard bit now is trying to source these missing parts 🙁

 

[hanskerensky]

Well, finished publishing most of the pictures from the Winder mechanism.
As you stated before you are missing that spacer ring.

Still wondering about that black ring on your photo because i didn't find it during
the removing of the winder. Must be from another part of the Nettar or maybe
even doesn't belong to it.

Regards,
Hans

Thanks again for all of your help Hans.

It looks like i'm just missing that spacer and the top screw.
I think I can sort out a spacer (even if I need to make one), but would have no idea where to track down the little screw needed to keep the whole thing together.
Does anyone sell random parts from these, or should I probably just look for cheap broken camera to repair my current one.

Oh, also, can you do me one little favour? Are you able to give me the dimensions for that round spacer?

Cheers 🙂

If he can give you the length and pitch and threads per inch or cm from the screw, it might help you find one or have one made at a machine shop.

Thanks again for all of your help Hans.

Cheers 🙂

Spacer should be easy to make. All dimensions in mm :
Outside Diameter 10, Inside Diameter 3.5, Thickness 4.2

The screw holding everything together is a bit of an outsider.
M2 is too big, M1.6 is too small. I suspect it is M1.7 but could also
be M1.8
Screwhead diameter 4.4 , Thread length 3.3
Probably this decorative type is hard to find but you could
first test with a normal cylinderhead screw and a washer.

Succes,

Hans
