Shop-made Ball Turner - with a Question

[tjb]

Getting a hexagonal pocket in the end of a hardened screw ... sounds like an ideal task for an EDM (if you have one)

Nope. I don't have one of those. As a matter of fact, I don't even know what one is. Never seen one. Never heard of one. Never used one. Never even watched a youtube video on one. The closest thing I can find by googling 'EDM' is 'Electronic Dance Music'. Even the name sounds oxymoronic to me. And, for the life of me, I can't begin to imagine why learning how to Moonwalk is going to help me drill a hole into the end of a case hardened screw. I obviously have a lot to learn about machining.

But thanks for the tip.

Regards,
Terry

Good one! Moonwalking is definitely not applicable to what we do.

The "EDM" I meant was Electrical Discharge Machining, also known as spark erosion. Just for fun, here are a couple of links:

Purchase Books, Starter Kits, PCB’s | Build your own HomeBuilt Electrical Discharge Machine (EDM) for machining hardened materials

www.homebuiltedmmachines.com

I've purchased Ben Fleming's book and the printed circuit board he's designed (second link). Right now I'm thinking about whether I can justify the time/space/cost of building one, versus how often I'd need it.

Now, that makes a lot more sense than Moonwalking! I suspect that's a good bit more involved than my immediate need, but it sounds interesting. If you choose to pursue it, I suspect many of us would like to follow a thread on the build.

Thanks for the lead.
