Guess what I did this morning
I just need to brag on myself. I am quite chuffed. This morning I took apart my upper thread tension assembly on my FW. I cleaned it and put it back together and I now have a nice stitch. I had been trying in my quilting group to do some FMQ and even with help from the others we couldn't get the tension away from really really tight. The discs themselves were clean but the big spring not only had some crud up front but the whole spring part looked like it had come out of a fire and was covered in what seemed like thick black soot. There was also some old oil on some parts and a bit of other crud. Wohoo. I am tickled. As you may have gathered I am not mechanically experienced. Cheers, for now.
