Ohh good THANK YOU!
@Efemera yes I am and have pondered this idea, but I be a bit o'fear yet messin with that little thing. I may try that though. I am not sure why I am so hesitant to change the bobbin tension, it is funny since I would take the whole machine apart with no reservations if needed. I did a google for bobbin tension, and ManSewing shows a nice way to test the bobbin tension, by holding the thread and try to lift the bobbin with the thread. It should lift and with a little yo-yo like motion drop down again. This bobbin does that with a very light yo-yo test. It will begin to drop if I raise it up higher, and stops if there is no movement. I would have to describe this as if it is floating in air, and any movement causes it to change.
@Bodgeitandscarper Yes The black is in the bobbin and the red is the upper thread. I should have left the pictures separated rather than combine them. The top image in the picture is the back side of the fabric and the bottom one is the top side. I also should have said that the image represents all of the tensions chosen
@StitchinTime I am using some scraps from a bed sheet, 200 thread count 60% cotton, 40% poly. I did this with a single layer and I did not think about the loop hiding between. I need to re-run this test using 2 and 3 layers each. I also need to do the raise the foot between the changes.
@Celia I am thinking this being stuck as the issue. I did try feeling the tension on the thread as I pulled it through the tension plates with the presser foot down, and as I pulled the thread through I ran through the dial 0-10 and I could feel a change from one end of the dial to the other.
I am learning, and beginning to see some things I should be watching for. I will run this test again but I will use separate scraps for each tension tried. I will run both 2 layers and 3 layers for comparison.
I did clean everything before running the test, using dental floss through the tension plates and through the thread path.
I would imagine the springs on the tensions plates are tired and need replacing. I am just amazed that if this is the case I am seeing worse problems...yet.
I will post new images better identified after re-doing the test.
Thank you again for the input and getting me on the right track here.
