Hi, it's me again.
I've found that another difference between the expensive saws and the Delta TS350 (the one I bought) is the smoothness of the cast iron table. Ony my table you can easily see the grinder marks and it has a few slightly rough spots where wood doesn't slide so easily (even afer waxing). I was thinking about going over it with 600-grit wet/dry sandpaper. Any thoughts?
