But just on back sticking. Sews heat with number 69 thread I believe I'm using 135 thread and number 20 needles. For the larger thread. It'd like when I back stitch through the previous stich it affects the tension of the top thread like resistance wise. I make a bunch of leather bags and hats . But primarily leather and I have a tipman boss and I know sewing tooling leather and dryer leathers are way different than sewing chrome tan oily leathers. With a machine. I had a old Adler shoe patcher and it didn't bunch on a back stitch. If it bunched it done it all the time same as the boss. This is a new one for me any suggestions . Thanks I think you are using way too small of needle for 135/138 thread. With 135/138 thread I believe you need to be using a size 22 or 23 needle size. Quote
Members dikman Posted January 7 Members Report Posted January 7 Yep, needle size was mentioned earlier in the thread. Quote Machines wot I have - Singer 51W59; Singer 331K4; Seiko STH-8BLD; Pfaff 335; CB4500. Chinese shoe patcher; Singer 201K (old hand crank)
