Question about Simplicity Frontier SL390 Mechanical Sewing Machine
I was sewing late and was trying to do a tight corner without cutting the fabric so I pushed the cutter away from me, and it jammed into the feed dog plate and stopped sewing. My husband opened up the compartment found that the upper looper was running into the lower looper preventing them to miss each other. Noticing that the lower looper was skinnier and curved behind its head he figured that the arms got thrown out of time and that the arms would just need to be adjusted manually to allow the arms to miss each other again. He loosened the upper and lower loopers at the hex screw on the respective drive shafts and was able to allow the arms to miss each other, but the threads would not chain properly so he tried to adjust them again. Now the threads will not chain at all. The arms seem stiff enough that they would not have been bent from the impact of the cutter and we are hoping that it is just a timing issue. How can we figure out the timing of all the parts so it will chain again?
If you look closely at the components of the machine they should have small marks on them that line up with each other or marks on the case. most sewing machines are timed this way the marks have to be lined up on both arms and that should work.
