Matter of fact it was very common back in the day...excellent repeatability and efficient use of materials....split mandrel gives the entire shape profile.
Very nice. A business can not be profitable with hand labor. While some bemoan CNC as NOT true spinning, it is. What it is not is HAND crafted, a person in their garage can be hand crafted, a business needs to be cost effective.
Your points are true in many respects although artisan and custom parts as Asaf points out are often the exception as are short runs, some people are still making a living hand spinning in these niche areas. Purely from watching loads of videos of CNC and manual spinning it seems to me at times as if hand spinners are not always that much slower than CNC, I get the impression that the material itself sets the pace and a CNC machine cannot spin much faster than a good hand spinner in some cases ( the hand spinner is probably going to lose as the material gets thicker ). I dont suggest that CNC is not the most cost effective in many cases simply an observation that when you compare manual vs CNC across various machinining processes then spinning doesnt look to me like the one with the biggest difference - I think there are other areas where the machine beats the craftsmans time by a bigger margin - good hand spinners can be amazingly fast.

Hi Lukas On most hand metal spinning videos you will find a comment just like yours. Experienced metal spinners seem to differ in practice and opinion. Some take the opinion that glothes are dangerous, hands less likely to get dragged in where they do not belong if not wearing gloves. Some spinners wear glothes impregnated with grease so they can lubricate the spinning metal disk easily - others use a "dolly" to smear the disk with grease. I am learning to hand spin at the moment - only three months experience so far. I do not wear gloves - I would rather risk a cut than get pulled in although I think the only real defence with machinery as unguarded as this is vigilence and methodical work practice - perhaps the person who does not "feel protected" has the better view of the danger. I put effort into keeping the edge of the disk trimmed, running true and free of swarf and I sometimes stop the lathe to see just how smooth I am keeping the edge of the disk - my reasoning is if there is a chance that something might cut you then take an interest in how jagged or smooth it is.
Neat video, but I don't know if I would call metal spinning with a CNC lathe "true craftsmanship". I would consider "true craftsmanship" spinning with hand tools.
You call that craftsmanship ? No that is a machine operator. In other words skilled labor. Craftsmanship has a lot more human interaction and creativity with the final result.
+Zeshan Sarwar Do you think that machined learned to shape metal by itself? Someone had to program all the moves into the machine, someone who is skilled at metal spinning.
+mikerjuk That is the reason I called him a skilled worker. For example a car being produced on an assembly line with help of human operators would not be called craftsmanship. However, a car designed and crrated mostly by human hands will be considered craftsmanship. Anyway, this is my opinion. You certainly do not have to agree with me.
A craftsman is a skilled laborer. A CNC lathe is still programmed by a person, they're just not making the final product in real time, which affords them many, many advantages that allow a more consistent, higher quality final piece. There's a reason just about everything in aerospace is CNC.
Zeshan Sarwar Zeshan Sarwar you need to actually learn the difference between skill and button pushing .. it takes NO SKILL to push a button .. the skip is that if the craftsman who works the material by hand and by eye .. sadly university engineers who try and design machines have no idea of craftsmanship because they spend little if any time in the trade learning the "Hands On" ... ...
The surface finish on that last pass is fantastic!

Wow, what a nice phonograph horn you could make with that.
TRUE SPINNING is done with hands!!!
@TheManFromAlaska i will have to agree with that with cnc you do get a consistent finish and productiveness but
Ever thought of building two stroke exhaust systems with this technique?
U are right Dominic.
عالیبودومفید.،👌👌👌
Ola belo trabalho qual foi o metal usado , e possivel fazer em aço inoxidavel
Agreed..!!!!
viva il made in italy
Very nice.

Not always. special custom made parts is where hand made lives.

caraca muito bom,mas demora muito eu fiz uma luminaria de 500mm de altura comfira, como se repuxa inacreditavel mas é posivel,e comenta algo .
vase? lamp? spitoon?
well said
What is the price of this machine??
Wearing gloves on Maschines that spins?
Isn't that veary dangarous?

wow thank for the long text.
I've worked on the lath for many houers and thought metal spinning is the same.
greetings from Austria!
I hope that you write it in your manual at least that you shouldn't wear gloves while operating the machine.
Good ^^

+mikerjuk Actually, the software calculated how the machine moved.

no craftsmanship here... just automation
Put this vid on Redtube, it's porn for machine manufacturers !
@tm868686 hands are overrated at all :D
