It's like leaving a chuck key sitting in the chuck - I get nervous just seeing it done, even on video. In normal cutting procedures it would be absolute insanity to touch the part. Too much of a chance that some chip didn't break off the parent part, and would whip around a slice you open like an orange. Treat machinery with a healthy dose of respect, or it will bite you eventually! Do you do any machining, Dan? @corinoco

Never. Never. Never. I like my fingers right were they are: attached. Pay me all you want, but I would never touch an object spinning on a lathe. Never. Never. Never.

I guess the video makes it look much faster than it is. Thanks for the info. I guess the video makes it look much faster than it is.

Incremental Sheet Forming: http://www.qmisolutions.com.au/article.asp?aid=160 http://www.qmisolutions.com.au/article.asp?aid=223 The concept is metal spinning, but CNC controlled so you can create complex 3d shapes.

Australia is lucky - this is one of the very few machines around the world that's open for inspection.

He's had occasion to have a new bell spun and says he's learning the trade now. Fascinating work. Friend of mine repairs old trumpets and sells them on ebay.

Whichever one has the least offensive taste because you do tend to get some thrown off the spinning metal. I like Dial. sniglet- most spinners I know use bar soap.

Having spent some time futzing round with a lathe and aluminum, there's a surprising amount of safe hand contact that can occur when working with things like this. I'd be MORE concerned about the carcinogenic effects of long term exposure to the skin of the lubricant he's using. If it's a wax or paraffin, no big deal, something petroleum based? Not so much.
