Jackfrost935 Report post Posted September 10, 2019 I was curious on what thickness of leather a singer 31-20 can sew? I’ve been trying to find a sewing machine that can sew thick leather for reasonable Quote Share this post Link to post Share on other sites
KAYAK45 Report post Posted September 10, 2019 Search this site and look up manual for 31-20. That will give you your answer! Quote Share this post Link to post Share on other sites
Bert51 Report post Posted September 10, 2019 Remember, the 31-20 is a drop feed and the ISMACS International wrote this about it. " For cloth. Throat plate flush with bed. Large bobbin. Max. stitch length 5 1/2 to the inch. Shuttle #20758. Clearance under the presser foot is 5/16". Speed 2200. (In catalog 10/1952) " I don't think it will handle 5/16 leather very well. Bert.

Wizcrafts Report post Posted September 11, 2019 It is a heavier than usual cloth sewing machine. It uses the same class 15 bobbin and shuttle as the 31-15. Quote Share this post Link to post Share on other sites
