vonL Report post Posted August 23, 2020 It's been a while since I last visited this thread, and not a whole lot of sewing, been busy with other commitments. Anyways, in addition to the 111w155, I found a cheap 111w153. I figured I can have one set up for fabric (denim etc) and one for leather and vinyl. The 111w153 came with quite a lot of schmetz 135x5 size 18 needles - what is the difference between this system and 135x16/135x17? I tried the web but am still blank. Could someone please enlighten me? Stefan:-) Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted August 23, 2020 System 135×5 is generally used in single needle lockstitch industrial sewing machines. It is also known as 134R, 135×7, 135×25, 1901, DPx5, and DPx7. This system is shorter than walking foot System 135x16 and 135x17. A machine using System 135x5 needles will have a shorter throw and won't accommodate the thickness that System 135x16 are capable of. If the 111w153 sews with System 134/135x5 needles and you are okay with its reduced thickness, stay with that system. Otherwise, you would have to raise the needle bar for the longer walking foot needles and make sure the hook arrives above the eye on the upstroke.

vonL Report post Posted August 23, 2020 Thanks wizcrafts! Yes, it appears to sew just fine with system 135x5, and thickness is so far no problem. And, thanks to Uwe's YouTube-videos I know how to adjust and time the hook and needle should I need to adjust for system 135x16/135x17:-) Quote Share this post Link to post Share on other sites
