The Singer Touch & Sew 770 needs accessories matched to its exact model. Two useful starting points are its slant-shank attachment system and bobbin reference #163131. Neither turns every item labeled “slant” or “Touch & Sew” into a confirmed replacement.
If you are bringing an inherited machine back into use, identify the machine and existing equipment before buying a large accessory kit. Keep the complete model label, manual and part reference together.
Recognize the wind-in-place bobbin
Manufacturer references: SINGER wind-in-place bobbin guidance; SINGER manual lookup; use Touch & Sew 770.
Bobbins: start with #163131
The Singer parts list covering models 737, 750, 755, 756, 758, 770, 775 and 778 identifies #163131 as a bobbin for the 770. This is an exact-model parts reference, rather than a match inferred from the bobbin's diameter or a general Singer family name.
The Touch & Sew wind-in-place system should not be supplied with a generic Class 15 or Class 66 bobbin. Check that a replacement offer names both #163131 and the 770, and read its pack quantity and included-parts description.
Follow the 770 manual for winding and threading. A new bobbin is not a guaranteed cure for thread nests or tension trouble. If problems follow a bobbin change, check the replacement identity and threading first; if the problem persists, have the machine assessed rather than repeatedly changing tension settings.
Presser feet: slant shank is the starting check
The 770 uses a slant-shank arrangement. This differs from a vertical low-shank setup, so a modern low-shank bundle is not a direct substitute merely because it contains familiar foot types.
Also distinguish a foot, a foot holder or shank, and a complete attachment. A snap-on sole may need a separately specified holder. A screw-on attachment may replace that holder. Check the exact item for 770 fitment and the equipment required to use it.
Its historical attachment list also marks Even Feed Foot Complete #506415-452 for 770. That reference is useful when asking about a replacement; it does not establish that a generic slant-shank walking foot is equivalent or that an offer contains the complete assembly.
Choose a useful accessory, then verify its reference
- Zipper work: choose the supported zipper-foot type for the zipper and sewing method. An ordinary zipper foot and an invisible-zipper foot serve different jobs.
- Quilt piecing: check the quarter-inch foot's model listing, guide, needle position and stitch restriction. Measure a sample seam before piecing the quilt.
- Layered sewing: an even-feed or walking attachment needs an exact 770 match and its own fitting and stitch instructions. “Slant-shank walking foot” alone is not enough to approve an arbitrary product.
- Buttonholes and hems: check which attachment and procedure the 770 manual specifies. Do not assume that a modern automatic buttonhole foot adds that function to a vintage machine.
Needles: use the manual's system and size guidance
Choose needles by the system specified for the machine, then by the fabric, thread and permitted size. A broad “domestic needle” label does not establish that every size or specialty needle is suitable.
Follow the 770 manual for insertion direction and safe accessory changes. Do not copy a needle-installation diagram from another Singer model. If the needle hits the foot or plate, stop and resolve the setup before sewing.
Keep related Singer models separate
A parts list can cover several models while marking individual components for only some of them. Read the row for the exact part and the column for 770. The existence of a neighboring model in the same document does not make every component transferable.
The same care applies to electrical parts. A controller, cord or motor needs its own model, regional and electrical match; a physically similar plug is insufficient. Use qualified service help when the identification or electrical condition is uncertain.
A small, useful starter kit
Begin with the correct bobbins, needles appropriate for the intended project, and the ordinary feet needed for the sewing you actually do. Add a specialty attachment once you have checked its exact model support and included pieces. This avoids paying for duplicate holders or a set with components you cannot use.
Quick buying questions
Does every slant-shank foot fit the 770?
The mount description narrows the search, but the exact foot, holder and operating restrictions still need to match the 770.
Can I buy any Touch & Sew bobbin?
Use the exact #163131 reference and 770 applicability. Singer distinguishes several wind-in-place bobbin designs; a similar name or photograph is insufficient.
What information helps identify an accessory?
Email Sewlume support the complete model, candidate part number, intended task and clear photos of the current foot or bobbin. Keep serial numbers out of public posts.
