It's a nice lazy sunny afternoon here....got all my chores done so I could sit down and run up a few seams using my grandmothers old 127k treadle: a maiden voyage after replacing her tension mechanism and belt and giving her a good clean over. Blast and bother but every couple of inches I'm getting a small run of dirty black stitches. I'm assuming it's the bobbin thread cause it's showing on the top side of my work as I sew. I have cleaned my shuttle, cleaned out the shuttle cradle and where the thread comes up through the needle plate, I have changed my shuttle, changed my bobbin and thread and am still getting these wretched black/dirty stitches. Can anyone advise where I should be looking further? Note, I haven't used any water to clean these areas, just a cotton tip and a little shell lite.
