Re: Sherline backlash
The Sherlines are good machines but they will take some fidgeting. Then when you get it right, it will go out of adjustment again. It always seemed easy to get into the .004-.007 or so backlash.
I used Moglice on the X and got it down to sub .001 but havent used it since (I dont trust the stuff but have no reason to feel that way). I have also purchased very small precision leadscrews with anti backlash nuts. At this time I havent figured out how to use them due to space constraints. Maybe in time.
A lazy man does it twice.
