crazymaker Report post Posted January 4 Hello all. I am not sure if anyone here has advice for my non-leather questions, but this site has so many members with an impressive array of information on machines, materials, projects, etc., I might be able to get better help than the guesses I have found. First the machine: A decade ago I found a 1942 111WSV65 (I can't figure out what was customized) and a bunch of thread spools at our dump. I finally absolutely need it for a project. I had bought an original 150 manual as that seemed to be the closet model. 137 x 17 is written on the cover. I cleaned and oiled her, and played a little with it. It worked well and I am comfortable with the clutch motor. The only obvious need was a new bobbin case spring. It had an old straight needle on it, and also some unused humped-scarf ones in an envelope hand-marked 135 x 16 # 22. All, including the old one are about 1 27/32". There was also old spools of thread; most are nylon left thread , some still have labels, 46-2 type SS. It is quite strong, I am sewing an average of 8 layers thin polyethylene woven tarps. I know the straight stitch is not optimal but it seems to work neatly and securely enough for this project. Might end up with about 8 stitches per inch. I'm looking for advice on what needles I should be using, and also thread - though I would like to use that thread if possible. I am sewing a large thing, a 24' x11', 10' tall attic. It is sort of like a tent, with an exterior frame. It'll be installed inside, so UV degradation of the thread is not a concern. I attached picture of the test runs. And, to give you a sense of my sewing, wearable boxing gloves based on the facebook like/dislike button, sewn out of cheap vinyl. I hope I have not made the files too small. Sorry for the long description, and thanks for reading it. Quote Share this post Link to post Share on other sites

For non leather projects, I recommend System 135x17 round/ball point needles. Round points won't tear the fibers apart like leather points tend to do. Some of the best are Groz-Beckert and Schmetz. I use both. The GB are available with titanium coating. They are labeled Gebedur. Schmetz makes a ball point needle with an extra large eye, called Serv 7 needles.

crazymaker Report post Posted January 6 Thank you Wizcraft, that is very helpful. Not surprising, considering all of your posts that I have read. And if you could, would you tell me if there is a size that I should be using with the nylon left twist 46-2 type SS thread? It doesn't look like it warrants an extra large hole. again, thanks Quote Share this post Link to post Share on other sites
