Nothing unique or revolutionary but I built it and here it is. :dremel:

And the results with coarse wheels on 3/4" 360 brass.

Knurls look good. I need to build one of those, someday. :palm:

I was going to start on a tip-up threading tool like Bogs' but with only a couple hours shop time I figured I'd save that project for another day.

Daft question - how do you make a knurled pattern that's wider than the width of the knurling tool (without loosing the continuity of the pattern)?

loply,

Thats not a daft question.
You just move the knurl tool along slowly and carefully. Whether you do it in one go or a bit at a time will depend on the type of knurl cutters you have. Mine are cheapo ones so I do it a bit at a time. You have to take it slow and easy, so as not to lose the pattern. Rigidity helps a lot in knurling.

So is their only two types of knurl pattern, diamond and straight?

I think straight and diamond are basically it nowadays, Bry. The knurling wheels come in coarser and finer varieties. "Rope knurls" were once available, but their use seems to be restricted to jewellery now. See http://www.gesswein.com/p-3029-large-millgrain-wheels.aspx and click on the thumbnail to see examples of rope patterns.

I have made some ropeknurl wheels and a siple tool to a friend that build cane rods. I'm sure they are available, but this guy wanted somewhat special size/pattern.
I have build some knurl tools, but completely hashed up my clamp type one...I tought I was clever and rushed it but instead I learned something: I's easy to have a bright idea - implementing it is another matter.
Knurler is nice when it does the job!

Nice knurler. I still need to make one of those.
For a while I got a bit sidetracked with the nutcracker style knurling tools. Got some nice designs out of Popular mechanics.
For those interested in making rope Knurls here is an article that I found some time ago:

Thanks chaps,
Rope knurl sounds good.

Great looking knurls! Congrats on making a nice device to do it!

Thats another one on the to-do list, two counting the rope knurler! :coffee:

Certainly not a daft question, one of the few things I learnt in "metalwork" as it was known in school where I come from, was knurling larger than the knurl. Well, the only thing that remains, is you use automatic feed, which I will have soon! I have some diamond knurls that have 20 TPI on them. The distance between the knurls when measured with callipers parallel to the axes of the knurl is 0.040".
Experiment!
