Well circumstances made my decision for me. Today, I visited Lowes looking for the Delta T-2 fence. No luck in this state. I thought I'd stop by Rockler since I know they do sell Delta. No T-2 but they did have on the clearance table, a Mule Cabinet Accufence w/6' rails. That is now installed on the Rockwell/Delta. For the price ($62), I really couldn't pass it up. It is a pretty basic setup, A front tube rail, rear angle rail, and apiece of extruded aluminum w/ T tracks, for the fence. I spent some time with a dial indicator squaring the table, blade, and fence. I think this is going to be a big improvement.
I'll be making a rolling base, cabinet, and legs for the extended rails in the next couple of days.
