Members Dave4 Posted October 23, 2017 Members Report Posted October 23, 2017 Greetings all, Photo: 2 feed dogs of different lengths. What is the functional difference between the 2 lengths? Is the shorter length better for curves? Any other differences, such as intended for different fabrics, uses, etc? Thanks! Quote
Members Dave4 Posted October 23, 2017 Author Members Report Posted October 23, 2017 Photo - other dogs with more rows and bigger footprint. Compared to the dogs in the 1st post, what is the purpose or functional difference of the dogs in this 2nd post? Thanks! Quote

mikesc Posted October 23, 2017 Report Posted October 23, 2017 Dogs in front of the needle make it easier to control the material when in reverse. Short dogs are better for curves. Quote "Don't you know that women are the only works of Art" .. ( Don Henley and "some French painter in a field" )
Members Dave4 Posted October 24, 2017 Author Members Report Posted October 24, 2017 Thanks for the replies. Searched around, confirmed it's mostly common sense: Smaller pitch for lighter work, longer pitch for heavier. Shorter row (tooth count) for lighter work and for curving. Longer row for heavier work and generally straighter stitching. More rows for heavier material, also helps with straight lines, therefore not as easy to turn. Singer 31 spawned a LOT of plate/dog combinations! Thx. Quote
