How Needles Are Made


There was some discussion of needles over at Caine’s [affinity] about how needles are made. I’m sure you’ll enjoy this!

It starts slow but it gets better when they start with the machines.

So, I was wrong about the needle being formed by folding and press/welding the material.

The way industrial processes evolve is so cool. It’s a constant process of tweaking things until they finally work just right, then “ssh! don’t touch it!” some parts are hands off, some parts are hands on, it’s optimized so that the machines do what they’re good at and the humans oversee the whole thing.

I didn’t realize that gold-dipping the eye-end of the needle was to make it easier to see the hole; I assumed it was decoration to justify a higher price. Watching the process also shows why needles aren’t stainless steel: some of the operations the machine does would be painful if you were using stainless stock; for example the polishing probably wouldn’t work at all.

It’s also interesting to see how they haven’t figured out a reliable enough and cheap enough quality check; a human has to review the product and pass it on. Back in the 90s I worked with a guy who had designed robotic bottling lines for Seagram’s and he explained that it was all completely automated. All those little nubs and stuff on the bottles? They’re to make sure the bottle rotates to the correct direction, so the cameras can “see” and make sure the fluid levels are correct. Think about it: when you’re building a robotic system that’s completely automated, it’s failure path has to also be completely automated. So, when your whiskey-level sensor decides a certain bottle is too low, something has to be done with it – you need a routing system that flips that bottle into a different line because the product is worth keeping. That probably doesn’t apply with needles. Industrial process-lines are carefully optimized along an inner cost/benefit/speed analysis.

gang-grinding an army of needles against a wheel

I’d love to see how this process evolved. It probably started from a jig that a needle-maker held the stock in, while they ran it against a wheel.

When I wonder such things, I have two “go to” sources – one is the Encyclopedie of Diderot and D’Alembert and the other is the Encyclopedia Britannica 11th ed. Diderot’s encyclopedia is a great portal into industrial processes circa 1770. The Britannica is circa 1910 and it’s on Project Gutenberg. [wikipedia link farm is prettier]

You can see the fellow over at Fig. 8 is painting the needles with abrasive and binder and rolling them up in a piece of leather. The machine you saw in the video is half-automating a very time-honored process.

As I expected, the Britannica describes a transitional form of needle-making. It describes how they did it in D’Alembert’s day, and the newer improvements.

I did not know that steel needles were introduced to Europe by the moors. See what happens when you have muslim immigration?

By the way, the screenshot from the Diderot encyclopedia is from Ebay (another place I often search for illustrations). You can have it for $15. There are horrible people who buy old books like the encyclopedia and break the binding apart, then sell the individual engravings as standalone artworks. I remember times my father would grab my hand and haul me out of an antique store in Paris or England, because the store was carrying ‘broken’ books that had been ‘asset stripped’ instead of preserved intact as they should have been.

You used to be able to get copies of the Encyclopedia Britannica 11th for $200-$400 on Ebay. I don’t know what it runs now, but it’s a great gift for the nerd of your heart. My dad’s edition had the backs eaten by mice one summer and he hired a friend of his who did 18th century-style bookbindings to re-bind them. They’re stunning, and they kept Mr F__ busy for 2 years. If any of you ever want me to look something up for you, just holler and I’ll pop the correct volume off the shelf and take some pictures with my iPhone.

The 11th edition is beautiful – you had some of the great lights of the day writing the articles, such as Albert Einstein doing the section on Physics. That was actually in continuation of a tradition started by Diderot, in which he got the sections done by the great students of the fields. Voltaire wrote the section on Philosophy (naturellement!) and was so inspired by doing so, that he went and did his own encyclopedia of philosophy (single-handed, naturellement!) which occasionally features in this blog. You can actually find old editions of Voltaire’s encyclopedia on Ebay for surprisingly reasonable prices. I think I paid $400 for my first edition, in 1999.

    It’s certainly a long way from scribing out needles blanks from a section of antler with a flint flake…

    On the topic of old books – I was rummaging through a bin of books at Goodwill and came across a copy of “Forges ou Art du Fer” by Diderot, Denis & d’Alembert, Jean-Baptiste le Rond (1760). The binding is missing, but the rest of the book is in good shape – I see on Abes Books that many of these have been destroyed for the plates (I see an intact copy, but mostly just the plates sold as a group).

    I find it distressing that people will destroy a book for ‘art’, even pulp stuff, but so much worse with old books. Not just to remove illustrations, but things like taking a book apart to ‘transform’ it.

    A propos of books….

    If you like books and old technology – especially woodworking – try Chris Schwartz’ Lost Arts Press. I have a number of items, such as the folio-size illustrations from Andre Roubou’s ” l’Art de Menusier.” Beautiful stuff.

    Disclaimer: I send LAP money, they send me books.

    That’s quite a find!! It’s pretty amazing what shows up sometimes in old used book bins.

    There’s no excuse for destroying an old book to remove art from it, now that scanners and inkjet printers are perfected to the point where the unaided eye cannot tell a scan/print from an original. In fact, a scan/print probably looks better, since the older paper lacks the kind of whiteners and surface treatments you get in high end printer papers.

    I wonder what Diderot would say. He’d have something to say about it, I’m sure.

    I’ll check it out. Sounds like it might be unhealthy for me (my bookshelves are always full and I have a “one comes, one goes” policy in effect…) That has resulted in most surfaces getting their own piles of books.

    ” l’Art de Menusier.” looks lovely! I used to know a self-taught French furniture-maker who had a copy of that in his shop! He did restoration work for old buildings – if you’re fixing up a 12-century castle, you can’t use Ikea-bolts. I think I know what my dad is getting for xmas this year! Thanks!

    Oh, that’s cool! I’d never thought of that as a problem but… of course. The abalone is so pretty, too.

    Strawberry: how interesting! It’s basically the same idea as an ‘uchiko’ (Japanese sword-polishing powder-pom) Hm. That might be a cool kit for needle maintenance.

    Marcus @10: I’ve done it (with red deer antler), although admittedly with the benefit of some modern tools. (No power tools though. That would really be against the spirit of the thing… A broken hacksaw blade makes a good replacement for a flint burin. The real thing is quite hard to make and my flint knapping is rudimentary at best.)

    You’re being pretty insufferable there. I have transformed books into art pieces, many people have, and they are beautiful, and yes, they are art. I love books, I have over 2,000 of them in my house. What, exactly, is it to you, if I took a book I purchased, and absolutely fucking hated, and turned it into sculpture? How, exactly, does it impact your life that I destroyed and transformed a DirecTV manual? What is it to you that I’m working on a very large piece which will take several years to complete, and involves destroying holy books?

    You should try to be less of a judgmental asshole.

    Dunc@#11:
    I salute you. You sound like my kind of crazy.

    No jeweller’s saw? You could saw a needle-eye in something with one of those; they’re amazing.

    You need to make a hole to use one of those, though. Heh, “it takes a needle to make a needle”

    Caine @#12

    Did I say you were a bad person for doing that? Did I say no-one should do this?

    No – I said I found it distressing. I do. And someone is being an insufferable judgmental asshole, but I am pretty sure it isn’t me.
