Hello, this is my first post here and thought that it might be an interesting question for a more in depth answer, having found literally nothing online.
I've spent quite a long time getting this working and it really does perform well and is very quiet indeed, I don't think it's done much work judging by the bed condition.
My machine came with a 1/4 piping foot, so I presume it was set up for quite heavy work, so my question is having looked at quite a few pictures of the 31K47 I see they come with a Bell crank driving arm 19358, where mine has a much longer crank part no SK26160, this I think will lift the outer foot higher in operation?, was it an option? I couldn't find the part number listed anywhere.
I would like to try the smaller bell crank, but have not had much luck finding one yet.
Cheers,
Sean.
