Pinsplitter Report post Posted November 24, 2015 Can I ask a bit of a dumb question. There is correct tension for the thread you are using, I set bobbin tension as a bit firm when you pull it by hand then upper tension to get the stitch centred in the material, so the stitch looks fine, but sometimes it seems not as tight as I'd like it to be. Is there a way to make a stitch tighter?Increasing bobbin tension to a point where the machine still stitches well? I have a Highlead flatbed and a Seiko CH-8B cylinder arm (like a 441).
