Hi fellas,

Hope you're all well. Nice and cool down here in Australia.

I'm trying to teach myself how to make nickel silver reel seat hardware for my rods. But I'm not sure how to go about typical knurling. I've got a few exemplars from what I consider to be well scaled and proportioned to the cap n' ring and I'd like to at least come close to that quality. The knurls are very fine, well shaped and well formed/cut.

Here are a couple examples

Rope Knurl


I'm trying to figure out if these types of knurls are "cut" knurls or "formed" knurls. Hints on how to make them are very scarce on the ground. There are quite a few YouTubes on knurling which are helpful but it still leaves me with those questions as NS hardware for rods aren't the typical examples in Youtube videos. Besides that the idiosyncratic details for NS knurling for this application are not treated anywhere I can find.

My other question is - where do i find such fine knurling tools?

If anyone knows something about this I'd be grateful to hear about it.

Cheers

The second pic with the dog head appears to be hand cut with either files or gravers.
Not sure of how fine but, knurls can be ordered fairly fine.

First pic looks more like "reeding" as found on some coin edges. Being NS, formed most likely, but cut generally is best on thin pieces. You can get just about any pattern you wish. Straight, left and right are common, but I'd think the rope may be a bit special.

Clickspring does some fancy knurling by making special knurls in his clockmaking videos, you might look at that.

Yes, I've seen a few of his videos.

I found what I've been recommended to be the tools for such fine work. These tools are used in the jewelry trade. They are referred to as a "millgrain wheel" of course there are different sizes and styles. I bought a couple of them. When I try them I'll post my results so you can see it.

Millgrain wheel tools

It seems to me that the key for me to find out what was being used for such fine knurling was the word "millgrain" . Put that into google and the right tools started showing.
