Reading the comments at the end of the article, including those of the designer, all of the above points have been raised. Looking at the video, it doesn't appear that rotating the table - and stopping it too - is much of a problem. I read through the article and didn't find where he addressed locating the pivot bearing on the center of rotation - I watch some of those car shows on TV and they put the whole body on a rotisserie to do the bodywork and painting, and they discuss finding the center so that the unit is balanced and doesn't "drop" at some point. I agree that the better solution is probably to build the unit so that the lift-off work top - and a torsion box is probably best, light-weight and still rigid - is at the correct level and live with the CNC down low. Mike's set-up with the collapsed worktable sliding under the CNC is good, but it requires enough floor space to have two units sitting there which may be a problem in some cases, I know it would be in mine.
I thought the builder showed a lot of ingenuity in the design which is what caught my attention. I'm not in the market for a CNC - too many other things I need to learn how to do first - besides my next purchase, when in dream mode, is a mini CNC Mill :smile:
