Thanks Mike.

You may want to practice on some scrap parts until you get the hang of it. No sense risking real parts while learning the process.

How can I mess it up?

I'm sure I can find a way; I'd just like to know what to watch out for!

Knurling?  Ugh.... let me count the ways I've done it wrong:

- the knurling tool isn't square to the work
- the OD of the work isn't a multiple of the pitch of the knurling wheels and never settles down into a pattern.
- on those cheap-ass 6-wheel/3 pair bump knurl, the axles are undersize, the wheels wobble, and your knurls look like poop.
- on a pinch knurl, you install one wheel of one pitch on the top, get interrupted by a phone call, and install a different pitch on the bottom.  You get an interesting rectangular pattern with that.
- you squeeze the knurl too hard and you get flakes of material coming off the work and the knurls look shaggy.

Here's a neat video on making your own knurl wheels from ClickSpring.

I was talking about screwing up the heat treating. I already know how to screw up knurling!

parts for that knurler really don't need to be heat treated

The only parts that would get it would be the knurl carriers.

I used 1/2" brazed on carbide tool bits to make my carriers out of and didn't harden them, used hardened dowel pins for axles and have never had a problem.

Finally made an arbour for the 2-3/4 HSS slitting saws that I bought.  This is the first time I have turned between centres.
