Nice Job Sir!
Just a suggestion here, but if you also make a single wheel tool on a round shank you'll be able to do straight knurling with a 30 degree wheel, possibly with some interesting slow spiral variations by varying the angle of presentation ;-)

Good thinking.I bought a single straight wheel knurlier to get the
sets of wheels included,i may be able to rework as you say.Also thinking about a vertical hinge pivot as the commercial ones to give auto compensation for self centering on height.Plenty to play at now the simple basics are proved
What I am happy with is its so simple to make and works so well

It's about having both wheels cut to the same depth, you should set the tool as accurately on centre height as possible, the adjustment is to let both cutters contact the work at exactly the same point of in-feed and ensure both knurls cut to the same depth, ideally you wouldn't want the head free to pivot whilst cutting. The commercial tools have locking screws which you slack off allowing setting of knurl wheel contact and then tighten to lock it for cutting.

John,
Interesting but aren't they Form Knurling tools as opposed to Cut Knurling?

Nick - yes they are pressure knurling not cutting. But Chris's videos are so well produced they are worth watching, if only for the entertainment value. The fact they are also so informative is just icing on the cake.
