What Did You Buy Today?

Along with 'Penn State' above I've got a more expensive 'bad move' story.
I had put on safety glasses and a shield to use my 4-1/2" but I had my new prescription glasses on a strap, dangling.
The sparks pitted the heck out of them.
Smooth move -EH? Haven't made that mistake again.

Well.... that wouldn't have happened if you weren't wearing a shirt! Just do your grinding naked. Wait that didn't come out right, this is supposed to be a family oriented site.

Reminds me of this.

Interesting video. I can't think of a single comment that wouldn't get me kicked off HM.

I thought of quite a few comments... but, as you see, I'm not sharing them.

Okay, maybe one- If I could read lips in Mandarin, I'd guess the child laborer in the background is saying in slo-mo: What the fff...!

New tool to learn about, I can only wish I can do a decent job learning.....

Joe Pie's video to start with.
And be very careful - do not allow _anything_ to get near the knurling wheels during operation.
And if you need a laugh check out some homebrewed tooling. Then look over @darkzero's posts for his works.

I've seen Will's awesome work, that's inspiring, and intimidating. I'm a total flunky at math, so I'm not sure how this is going to turn out.

No math. Find some aluminum and chuck it up. Go slow.
All the stuff I did, I didn't bother calculating the diameters. Parts needed to be knurled so they 'got' knurled.

What brand knurler is that? I really want to see how you make out with it. Mine is a disaster! Please start a thread with your adventure.

Me too. I just use an online calculator. I use this one except I have the formula turned into an app on my phone.

If going for a fully formed knurl on softer materials just have at it. Me personally I always calculate for knurling diameter no matter what. Double tracking bothers me.

Eagle Rock Knurlcraft K1-44. I use the same one.
