turn handle gets tight but we took machine apart and
turn handle gets tight but we took machine apart and nothing wobbles and all looks straight. Repair man said the bar inside was warped. Problem is the thread cont to break with sewing up in thread feeder up top not in the bobbin and repair man said the hand turn should not get tight and could not repair??? Is there any oiling needed to be done or other adjustment so I can cont to use my machine. He wanted to sell me a 4000 dollar machine.
