The cams are plastic which might be part of the problem but I will apply more T-F and some heat. Heck, I'll just put it outside tomorrow.
90+ degrees in the sun should be enough heat.
Does anyone here have a Singer Fashion Mate 362? I have one with a tension issue and was wondering if the darned thing takes metal or plastic bobbins which might be an issue if I am using the wrong one. I am just rehabbing it to give to a teenager to use to see if she wants to sew. I have told her mom that it is not a high end machine nor a particularly good one but mom wanted one with more than straight stitch. OK by me but her daughter may not thank her for the decision.
