Adjusting the Bobbin Winder
The bobbin does wind and fill, but uneven, filled full at bottom more than top, so not as much thread gets put on the bobbin. What can I do to fix this problem?
I have the solution for the problem you identified. The bobbin winder tension assembly is not positioned correctly. The tension assembly is attached to the rear post that the square tubing is screwed into. On the back side of that post is a set screw which holds the tension assembly in place. There is two thread guides that the thread goes through that keeps the thread in the two metal disc that applies tension to the thread as it winds onto the bobbin. Rotate those two thread guides counter-clockwise (left) 1/8 of an inch, tighten the set screw and wind a bobbin. The TinLizzie18 Team
