The Knurl's the Thing

Finally! Got the first 30 diamond knurl whistles turned this morning and got them finished up this afternoon. I spent several hours with the CNC shop yesterday and again today tweaking the darned things. It was time well spent though because we dialed in the knurl nicely in the end. What a tough one though, what with some tooling breaking and endless other little complexities that came up. Thank God I'm not a serious machinist and just play one on television! :)
