I'm in another house, now. complicate to explain, and to do.
to move house is not the best condition to cleaning machines...but.....I could see my others fiddlebase, a singer 12 and a kimball morton for verifying the mechanism, and I found an engraving[ATTACH=CONFIG]471335[/ATTACH]
so, now I can use correct names.
my pie slice is simply (too simply) called crank, etc.
I must confess I didn't remember if the crank made a complete and continuous rotation, or to and fro.
I saw now, my pie-slice turning easily on itself (in the other machine)
in Cinderella, today, the crank arrived to make the entire rotation many time but yet with a remarkable effort.
the very problem is that the vertical shaft is not 'soldered' to the horizontal one, the two screws in the gear are not able to catch it and make it rotate. why?
Because dirtyness is so strong to nullify the screws force? month ago I noticed, in a little chainstich, that the shaft rotation did not request a big grasp (? ) of the screw
It must be sufficient a force as that of two forceful decise fingers. am I right?
that I noticed is that if one know well as fiddlebase works the things are more easy...
