Necchi made the classic mistake of shooting too far into the future, but I love it.
It had real potential, they almost got it wright, it is a little reminiscent of the Lotus, maybe they were trying to get into the MoMa too.
Necchi Logica 592 by Ital Design Giorgetto Giugiaro
Giogetto Giugiaro The Genius of Design, given to me by my older brother.
I actually met Mr Giugiaro during a design review at the American Motors Design Studios in about 1988, when we were working on the Coupe version of the Eagle Premier. I was in Advanced Vehicle Engineering at the time working for Marcel Marchond, Delbert DeResse, and host of other good Engineers
I see it a little like my beloved Custom Imperial in that the Engineers were to drunk with the concept to accept real world usage/testing; the concept is great but just a couple of details could have been improved with a little user feedback.
So after using it for just a little while the the presser foot mechanism slowly froze up!
The pivot shaft had the original grease on it and it nearly stopped move all together.
I opened it up but it was so frozen I could not get the shaft out.
I worked it back and forth and remembered some of the test fixtures from work so I made this little device to move it.
All is well with the presser foot now.
Printed out the Logica manual free online and discovered a little more about the differences; the LOGICA has needle position in-place of the fast-slow speed switch. Its such an obvious option I guess Necchi saved it for their own release.
Made a bunch of pattern tests too
The Necchi also has access to an adjustment screw to tune the proportion of the pattern stitches; this is important to their electronics and is not available on the Sensor Sew
The Auto Back-Tack works perfectly at the beginning but of course does not know you are at the end of the stitch, and so goes forward three stitches from where you stop.
Made this super cool cover for the machine with help from Scott Tallenger of left handed branded
So using the machine is a different experience; the start - stop is not like a mechanical machine.
The ZZ moves at precise times and moves at high speed, when your eye is used to a mechanical machine this is unusual. I believe that I will need to experiment with the needle position to understand where the start of the motion is, it is hard to explain but the electronics knows where the needle is and decides how to complete the stitch from there, a more sophisticated computer system would likely act more intuitively. When you turn the hand wheel you move it to a computer governed position that is difficult to understand.
I still like it a lot and want to use it for fabric work, it is such a novel approach and as I mentioned it was so far ahead of its time that I will use it as a 1st prototype for the all electronic machine that I want to someday design.
Anybody want to help?
Regarding the revers button; since it lacks ANY tactile feel or feedback it is very difficult to mentally know you are on it. It does not take much pressure to make it work. So I added a little "dot" to it so I could find it w/o looking!
