Hi: Looks like a very good start! Here are my suggestions: Mount the ball slides as far apart as possible, would make the table more repeatable and stable. Look at adding flood coolant, it makes a huge difference by keeping the work cool and flushing the chips away. When I grind without coolant I often get burn marks.
The concrete bed and frame is a valid idea, some modern machines use epoxy/granite frames, I have epoxy/granite surface plate that was once certified.
