This chart is based on these excellent resources provided online by the Singer company:
- The 14T967DC Instruction Book that comes with the machine, especially the chart on page 8.
- The 14T967DC Overlock Workbook
- The Detailed Threading Guide - Quantumlock.
I wanted a more detailed chart so I wouldn't have to flip back and forth through the various books and files, so here it is.
- Stitch length is normally N unless otherwise needed; a range is given. Use shorter stitches (2-N) for lightweight fabrics, and longer ones (N-4) for heavier fabrics.
- Set pressor foot pressure to N unless you are sewing particularly light fabric (use pressure smaller than N) or heavy fabric (use pressure larger than N).
- Cutting (seam) width dial allows these ranges:
- Chainstitch needle: 7.8mm to 9.8mm (N=8.8mm)
- Left needle: 5mm to 7mm (N=6mm)
- Right needle: 3mm to 5mm (N=4mm)
- Set differential feed dial to N
(1:1 ratio) unless you want to:
- Gather the fabric: use numbers below N.
- Stretch the fabric: use numbers above N.
