Video of an industrial sewing motor pulley being made

[Gregg From Keystone Sewing]

YouTube link for video that I wanted to share.

I  waned to share this video on Youtube of a guy making a replacement pulley from stock aluminum.  I know some people here may enjoy this type of thing like I did.

Thanks Gregg - I really enjoyed watching the video.  I have always wanted to learn to be a machinist, but I think I am running out of time - too old and too many hobbies already!

Thanks for sharing Gregg - I too enjoyed the video - quite educational.  That fellow must have a fine machine shop.

Ooooh! Machine porn! Now that's a video! Thanks! I liked how he said "you could simply buy one"...but, NO!

Thanks for posting that, Gregg, always good to see how others do things. It's a very well made video (and an Aussie too, by the sound of it).

Thanks that was enjoyable and I can identify with all the comments above... would love to be able to do that but...alas.. time.. money.. space... love watching it done... and ya you could simply buy one but why if you can make one?

So in down under, "aluminium" is the word they use for free machining bronze?

Umm, no, we call it aluminium, you yanks call it aluminum. Nothing to do with bronze.

I think JLS was just pokin' a little fun at the Clickspring guy for saying it's aluminum when really looks like yellow metal at places in the video ( the aluminum pulley and the steel shaft.. even the white of the superglue tube has a reddish yellow hue ).  It's probably looks that way due to the very warm lighting used for the video.  Clickspring mostly uses brass, so the lighting is well suited for what he normally does.   

That said, I've subscribed to this YouTube channel for quite a while now.  He doesn't post often, but when he does it's usually pretty cool.  He has built a beautiful large mantle clock from scratch using machine tools, and is currently building a replica Antikythera mechanism using techniques and tools (which he also makes) that would have been available to the ancient Greeks.

Very cool.  The comment he made towards the beginning of the video about the broken pulley being made out of zinc and having been pleased with the service life of it before it broke, made me think maybe he wasn't too pleased since the new one is made from an aluminum billet.  That one should last slightly longer than forever.

Yup - video makes it look gold... probably camera settings and lighting.  Machines like aluminininim, but look like brass or bronze in the show.  Maintenance in a former life, I've tore up a chunk of 6061 a time er two...

Even if it's something most us us won't ever do, it's fun seeing another bit of backstory to the process.  He did go out of his way to demonstraight gluing the pulley blank to an arbor, which seemed like a stretch, but it was a well done interesting video.

Yup did a lot of that stuff as a "maintenance man". A lot of math to  machine a pulley, but it sure is fun! Thanks for posting it!

No he doesn't. He has a tiny space about the size of a walk in closet. He has a small, benchtop lathe and mill and a couple of other pieces of equipment but that's it. There's a workshop tour online somewhere.
