Lathe Dagger

nice work - and while everyone else wants to see that knife stuck on the end of a rifle, I'm thinking it would be a major hit at the highland games.
 
Looks like you got your knurls crossed up which actually came out evenly spaced and pretty cool!

The tips that Nathan and others have given for knurling are spot on. I would add that once you start knurling, take a wire brush and brush constantly on the back side of the part while the knurl is working on the front side. Some Tap Magic will help keep everything lubed up.

I don't think there is much of a science to getting a nice set of lined up diamond knurls. Make sure it is as square to the part as possible and also aligned vertically so that the rollers touch the part at the exact same time. Take an extremely light cut in one place. By this I mean crank the knurling tool towards the part until it begins to make markings. Just enough that you BARELY mark the part. You may even want to throw some Dykem on so you can see the very faint cross hatching from this first light cut. Be sure not to feed the tool left to right at all if the knurling doesn't look like you want it because you will put tiny marks all over your part. Continue to do this and play with the alignment until you get a nice diamond shape. Once you get that, you can start taking more of a cut and forming the knurling.

Because you are moving the metal in knurling more than you are actually cutting it, the tiny scratches that you put in the part while getting the knurler set up will go away as cut deeper.

Everyone has their own opinion, but this is how nice deep knurling should look IMO.

Thanks guys!

AWESOME, thanks for the tips and tricks!! I will try it again, I think a big problem was I didn't bear into it enough, just lightly touched it.
