The newer Vertex ones are nowhere near as good as the older ones and there are a lot of cheap copies out there too. Adjustable engagement is a must. Bearings on the rotor and worm shaft are highly desirable if you are going to CNC one. A lot are just cast iron plain bored, and badly too. I've CNC'd a few over the years, the one I use now is a Shoba, problem is they don't make anything, they buy in and sell under their name and quality varies hugely. I made a new worm and drive shaft, the pinion was OK but the worm thread was crap and made of butter. I also added thrust and roller bearings to the new worm shaft. I ran it in with an electric drill and fine lapping paste on the teeth for a couple of hours in both directions and backlash is negligible now. Even so, as Dave said, it's better to run the code in one direction where possible :) Steve Blackmore -- ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
