Not really I have the time, equipment and the skills but ballscrews are hardened and the indexable tips required cost me nearly as much as what I get charged.
So to me it's not worth the hassle and all thou unprobable still possible risk of error.

RE: 1610 or 1605. I should clarify this depends on the intended use of the machine. If your going to use it to cutt intricate jewelry or want very fine detail then the small pitch is better but for a general allround machine then 10mm pitch works best in my experience.
