Clamp type knurler (pictures)
Got a job to knurl some 3/4 aluminium pipe about 1.5metres long. My only knurling tool I had was one of the types you push against the work and for this job it would be useless as it would not work well when in the middle of the pipe unless I used a travelling steady. So I went ahead and made a clamp type knurling tool....It is a pretty heavy duty one and was not made to any particular plans, just what looked about right..
It worked well, but I had to set up the travelling steady to stop the pipe from wobbling when the knurler moved towards the middle... The orange/pink stain you can see is the mark out fluid I use...It is copper sulphate and a nitric acid mix to put a thin layer of copper on the steel to make lines easily visible..

nice one, now I have lathe envy!
Got any pics of the final product? I'm yet to knurl anything.I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.

I wonder if you could make a plain third idler roller out of a soft material on a clamp knurler. You'd need to make a kind of cam arrangement on a ring to drive all three arms in at once but you wouldn't need a steady anymore.
