John D Report post Posted September 9, 2013 Ok I recently purchased an Adler 30-70 and in the manual it has the following information regarding needles and thread: <quote> Needle System: 332 LLG and No.: 110 - 200 Thread (silk substitute): SE 10-24 </quote> So far I am translating this as: 332 system but make sure you get the larger longer needles for the 30-70 and opposed to the 30-10 or 30-50 patcher. The "No." (I read #) is the diameter of the needle in mm (110mm to 200mm). Here is a link to a chart I found on-line http://www.universalsewing.com/tek9.asp?pg=needles_other). According to the chart the 110mm to 200mm for the 332 style needles translates as follow: 110 -> 2 120 -> 3 125 -> n/a 130 -> 4 140 -> 5 150 -> n/a 160 -> 6 170 -> n/a 180 -> 7 190 -> n/a 200 -> 8 What in sam hill does that mean? Lastly how does one translte SE-120 to appropriate thread? In one forum I see use 69 thread for the adler 30-70 and 69 only, and in another use 138, and in another use 138 for the head, but only 69 for the bobbin. And finally can anyone confirm whether 332 LLG is the same as 332LL? Thanks and if I have managed to post this in the wrong location, please let me know. John I found the following chart that seems to help a little bit, but the details are still immensely fuzzy in my mind. Quote Share this post Link to post Share on other sites
