All this information is just my opinion from experience and research. The eye is not the same distance from the shank head. Here is a 206X13 that is advertised to work.įree Westinghouse Sewing Machine Serial Numbers NumberThe 206X13 needle is about the same length, but it is not a match. There are other needles advertised at this length but the eye is not at the correct location. If you look back at picture 1 and 4, you will notice that the NLB needle (CC1221) is very close to 1 7/16' in length. There are several different Needle part numbers out there that may or may not work consistently with your machine.
Too great a distance to pick up that upper thread consistantly with todays standard needle. If the needle shank was longer, that 'Eye to hook' distance would be greater. Notice the distance of the 'Hook Point' above the 'EYE'.
This is a picture of a properly timed NLB and a CC1221 needle.
I have tried this process with great success. If you try this grinding process yourself, please wear the appropriate safety gear. When the hook passes the needle on any sewing machine it must be within a proper range from the EYE to be able to pick up the upper thread consistently and at a high rate of speed.
