[QUOTE=KenmoreRulesAll;6862403]Most disappointing to me are the beautiful machines with plastic/nylon innards.
In some cases I've read that people have repaired their plastic/nylon gears/camstacks with super glue. This is an area that I foresee in the future someone will start making replacements with a 3D printer. It's already been discussed at some length on the vintage Necchi Yahoo group as there are two Necchis that are infamous for a plastic part. The Lydias camstack and the Supernovas worm gear.
