I will look at the information that you have persented in your reply. Thanks again.

The information was helpful. It was a very good start. From the numbers given, I have two of the cams and the proper location and orientation for them (as far as top or bottm of the stack). The middle cam is probably smaller than either of these two cams so I now only have to try a few of the smaller middle cams to see if I can get the proper stitch. Hopefuly it will work out.

After some more playing with our machine, we have found out that the factory assembled cam stacks, such as #III, #IV,# V,#VI etc) are actually fairly easily taken apart into the separate components similar to those that the user needs to build the designs in the manual. The individual cams in these stacks of three have numbers on them to correspond to the design configuration wanted for the various stitches. The only cam stack with our machine that is a single cast piece seems to be the button hole cam which is designated as cam stack #II and also has a handle cast with it. Maybe the design of the cams was changed during the production run of this machine, so that the factory ones cannot be separated into the individual components.

Thanks again for the information about the necchi user group.

I agree, vintage Necchi sewing machines are in a class by themselves. Absolutely a joy to own.

I do not have a VII cam, however concerning the other two, the I and VI: Individual cams that make up those configurations are not present in my group of cams – they are all a different shape from those found on the I and VI. I has on the underside of the top cam, a #2, on the topside of the bottom cam, a #3, and on the bottom of the bottom cam, a #4. No doubt that is of no help to you. The VI cam just has a 7 digit product # on it, partially obscured where the cams are joined together.

Your best source for information on vintage Necchi’s is at the Yahoo group, necchisewingmachineclub. If anyone knows of a configuration (many have even tried to make their own cams) these folks do.

They are very helpful and many will volunteer information, sources, and even extra cams if they have them.

Best of Luck to you and your family.

The only things of importance that are missing are the competed cams: I (Greek Key), VI, and VII. I do NOT want to purchase these, however, Is it possible to see what individual cams are used in these completed sets, so that I can make them up from the single cams that came with the package. (The numbers are stamped on the cams. One on the top and a second number on the bottom since reversing the cam installation will have different results). In the instruction booklet they are only shown as the completed cam stacks I, II, III, IV etc…(on page 118 and 119 of our manual)

The completed sets come in series of 3 stacked cams. As far as I can tell from their positioning in the stacks from Bottom to Top, cam position 1 controls the feed dog (rate and direction), 2 controls the Zig Zag aspects of the machine, and the last cam Number 3 seems to control the needle position.

The design Graduating Knob seems to have a continuous gradation as follows 1 – 30 stiches per revolution of the cam stack; 2 – 50 stitches per revolution of the cam ; 3 – 65; and 4 has 159 stiches per revolution of the cam. At least that is what it seems to do on our families used machine. You can set the knob between thes numbers as well.

My wife, myself and our three children have all learned to sew on this machine. We really like it, but we are still beginners. It is a great machine, and even makes us look like we sometimes can sew something decent, however I am probably the worst of the lot. Still it is a lot of fun.

Anyway, if you can, could you please send us the information on the numbers on the finished cam stacks I, VI, and VII. It would be appreciated if you could find the time to do this. Thank you for your help

Sincerely

Peter and Catherine
