Can someone advise me about knurling, please?
I've been using an Eagle Rock scissor knurling tool with a couple of medium diamond knurls for some years now with satisfactory results.
I've never given any thought to the work-piece diameter in relation to knurl pitch and have always managed to get fairly clean results - mostly in brass and alloy. Not quite sure why but they always seem to turn out ok.
What I'd like to do now is buy some sets of straight knurls but never having tried these before, I feel I need some advice.
For example, I assume it's critical with straight knurls to calculate the OD of the work piece as a multiple of the dia or pitch of the knurl.
What I don't understand yet is how the two knurls are positioned so that they mesh male to female so that the crest of the "male" matches the trough of the "female"? Just thinking about it, I can't see how you prevent crest meeting crest and ending up with double-tracking.
Any advice would be much appreciated.
