5050c bobbin wont wind - Singer 5050 Mechanical Sewing Machine

You will have to wind the end of the thread around the bobbin a few times for it to grip first. Or even hold the end till it grips and winds naturally.

make sure you have pushed the bobbin forward so that the belt will turn the "dowel"

My Brother has another spindle to wind the bobbin. Be sure to thread the thread through the two loops. I wind the thread around the bobbin a little and then start the machine. I find that using the cutter on the bobbin spindle helps to hold the thread on place.

Threading the bobbin - winding thread onto the bobbin.

Position the new empty bobbin onto the vertical bobbin rod next to the end wheel. Click the rod to the right to engage drive. Hold the outer end wheel with left hand, and rotate the inner wheel anticlockwise by about a 1/2 turn (it stops) this removes drive from the foot and needle mechanism.

From a spool of thread on the top, thread to a loop/post on the left on the top. Then back to the bobbin you want to wind. Thread through a hole from the inside-out. Hold the thread vertically above the bobbin while you depress the footswitch to start winding. Let go when it's turned a few times.

Move bobbin shaft left, and tighten end wheel after winding enough.

Fitting bobbin-

Move footplate towards you, insert bobbin in hole so that bobbin rotates anticlockwise when thread is pulled, then pull thread into the fine notch towards you. After this position thread away from you, and slide the footplate closed.

To start / load thread. Hold the end 3" of the thread through the needle behind the sewing foot. hand crank towards you to sew first stitch in air. This should retrieve the lower thread - which you can catch with a handy pair of scissors. Then pull both threads rearwards - ready to sew.
