Gerry, What happened to the image link that was originally posted? And why does the forum replace some web addresses with ***********'s?
I was thinking of the V thread from an accuracy point of view - I can buy ground threaded rod and a tap to cut the delrin. To do this as an Acme thread I would have to cut the thread on both the lead and the nut. This would also mean having to grind tools to do the job - surely a V thread and tapped nut would be more accurate than a lathe cut thread? |
