Wizcrafts Report post Posted January 14 @1985, I moved your post from Help Wanted to Leather Sewing Machines. This is where you will get answers to questions about machines and needles. Help Wanted posts and replies require a moderator's approval before they become visible. I can tell you with certainty that synthetics and cloth require round/sharp point needles, no matter what system a machine uses. Leather point needles are specifically designed to sew leather and other animal hides. If you use round points to sew leather, the holes will be unsightly on the bottom and the needle may even get stuck in the leather. If you use leather points in cloth and synthetics, the slicing point may sever the fibers that hold that material together. However, a triangle point or diamond point leather needle is less likely to cause as much damage as a chisel point. Webbing and elastic are synthetics where you should always try to use a round point needle. With Velcro you can use any point. Vinyl (e.g., Naugahyde) doesn't seem to care either way. Denim doesn't like leather points at all. Garment and chap leather can be sewn with almost any point, unless the bottom is going to be visible and looks bad with a round needle. Patches are best sewn using a round point needle, even if they are on a leather vest. The back side isn't visible and a leather point needle will cut the threads on serged borders. Also, since most vests are lined with satin lining, a leather point will sever the fibers and the lining could run. Thus, I use round point needles to sew patches onto anything. I hope this helps.

Yes, you can strop them and polish them. I wouldn't grind the points on a stone wheel. Rather, pull them on Emory cloth to deburr them, then buff them to a shine using green or brown buffing compound. BTW, here is a handy needle and thread chart to get the best combinations for various sizes of thread. Quote Share this post Link to post Share on other sites
1985 Report post Posted January 14 Noooow, not a stone wheel ,I have a good collection of Japan / American and England / Greek and Belgium fine honing stones that I use for my straight edge razors , And strops with compounds, that`s what I meant to use on bringing back the blunt leather needles, Some time ago I bought a fair bit of different thread spools from a closing down industrial place that sold spools to companies,anyway they were kept sealed and placed in a cool dry dark area, I check them from time to time, and still great, I really should document the types I have on paper, and check what ones can be used on my machines, with needles to match, When I look at the chart I take it the metric is for over here UK England, Quote Share this post Link to post Share on other sites
