Fitting ball screws to Chester 16V

[Tom_Nelson]

I'd suggest going and finding some X2 mill conversion threads, as the 16V looks reasonably similar dimension wise, so I'd imagine space limitations will be similar.
The big thread I'd suggest is Hoss's conversion one over on cnczone.com, but the SX2 is quite a popular mill to convert so there is plenty info around.

Thanks for the lead - I've spent some time going through some of those threads, and I can see that in general it involves some machining out of the x-y plate where the leadscrew nuts are mounted. Given that I don't have access to another mill to do any such machining, I think I'll try a stop-gap solution by making delrin nuts to use with the existing leadscrews and see how much that improves the backlash and how long they last before they start to wear. I found this thread on another forum which looks quite interesting and I have a couple of delrin blocks available, so it's worth a try. http://bbs.homeshopmachinist.net/thr...s-the-easy-way

I'll post my results once I've tried making new nuts.
