Riccar Super Lite
A while back, a lady asked me to look at her 3/4 size Riccar R619. She was frustrated because her thread kept breaking. I checked it out and saw that the upper thread was catching in the bobbin area.
I inspected all the parts in that area looking for a groove or burr that could be preventing the thread from sliding smoothly.
Not finding any obvious problem, I began changing parts. I changed the bobbin, bobbin case and shuttle but the upper thread was still jamming around the hook.
I was forced to admit failure and returned the machine to her. That was about a month ago. This week, the lady brought the machine to the shop, said she has bought a new Janome and gave me the Riccar to use for parts.
Now I am on a mission to figure out the cause of the problem, just for my own education. I haven't had time to fiddle with it yet, someday I will drag it out and see if I can redeem myself.
