rope knurling tool

Hi im looking for a rope knurling tool. Can you buy such a tool ?

Have a look on Clicksprings web site for videos.

yes that looks to be my only option at the moment. not sure on making the tool though. looks alot of work

I have seen them for sale somewhere but they weren't cheap. Lots of stuff on the net about making your own from silver steel suitably hardened and tempered. I think one tutorial I saw used a single point cutter so maybe not too much of a chore to make? Good luck whatever you do.

Just found this if it helps. It talks about using a thread tap as a cutting tool.

Similar to clicksprings here from an old post on the forum

Hi Michael,

What sort of size and geometry were you thinking of? ...and is it for mounting in a lathe, mill or a hand tool as shown in Vic's link? Or do you just require the knurl to mount in an existing tool?

Not really sure. i just like the look of them and thought i could make some nice thumb screws on the lathe

Thought i could use one of these to make one. What do you think

Somebody with more experience than myself could probably say for sure but I think those are for cutting angular faces.

Knurls are usually formed by pushing the tool into the workpiece as opposed to cutting, although there are cutting type knurls for diamond patterns I believe.

Sorry i was referring to using it to make the knuring wheel. As in the click spring video

Yet another source of ways to make a rope knurl is on Frank Ford's site

Lots of other interesting things there as well.

Hmm. Seems that Frank Ford is another that advocates using the kitchen oven for tempering. Two of us obviously getting it wrong.

Regards Ian.

Ok looks like im gonna be making my own tool to make one. All i need now is an indexer oh and a milling machine.

where did i put that credit card

The Cousins cutter you linked is intended for cutting the minute 'shelf' that a precious stone sits on in its setting. That is why they list a wide range of sizes, as they need to be the right size for the stone. You could use on as a milling cutter to cut your angled grooves, but the cutter may not last very long, as they are made to cut silver, gold, and platinum. None of these is remotely as hard as tool steel even when it is soft. And I'm sure that any guarantee claim would be thrown out as that is not the purpose of the tool. Sorry.

Regards, Tim

I would only expect it to last the time of cutting the knurling wheel. So i guess its a case of suck it and see. if not ill have a go at making the tool to make the wheel as well. first time for everything

I think this is http://www.zeus-tooling.de/en/products/knurling-wheels/special-knurling-wheels.html what you are looking for, no doubt it will be expensive. Niko.

Hi Michael

A bit late but found your forum note on rope knurls.

AccuTrak in the States make them and their UK agent is

ATM Machine Tools

Unit 4 Molly Millar's Bridge, Wokingham RG41 2WY

+44(0)118 977 0099

They are very expensive ~ GBP200 each.

I have been making various 'old style' Morse keys and have used the knurl on the screws.

I made a knurl using ClickSpring's video and it worked but it was not fine enough for instrument type terminals.

Kind regards

Alan

When I made my synchronome (well it's nearly finished) I made a knurl by free hobbing a silver steel disc with a (4BA?) tap. The tap was held in the lathe chuck and the end supported in a female centre. The subsequent screw heads did look nice if I say so myself. It's easier than you would think and in brass with small fine knurl you only need the one wheel.

regards Martin

There was something about making one using a tap as a hob in either ME, or MEW.
