When I bought my rotary table I deluded myself into thinking a four inch would be plenty, and to top it off went cheap. Worked ok but should have went bigger was the thought during the first job. In hindsight after having to make a 6 inch dia fixture plate for the second job I think an 8 inch table would be better but is wider then my mill table by a bit so 6 may have to do. I think this all reinforces the buy as big as you can fit and afford. That looks to be a fine example of a good table and decent size so when you get it cleaned up it should be an asset in your tooling inventory!
