this is the actual condition of the work. notice that if the flash were a diluent or soap, it was powerful.
the little parts you see are more more dirty than in pic the bobbin is ready for sewing, but the same thread seems black nylon. I wonder who and when winded this last bobbin.....
an see we removed the long piece connecting the sticky shuttle carrier to the biggest piece (what is its name? I forgot...
) so the shuttle and its carrier are free to get a bath
now I went to the mistery:
the big piece now can move and rotate. it transmit movement to the feed dog.
the group needlebar presser foot, is away, searching a bathtub
the couple od cog wheels does work
BUT
the vertical shaft can't rotate
I only move the big piece with my hand
or the cog wheels by handcrank
what you say about? I re post one of the yesterday pics..
