I thought the extension table was kind of cheesy too Robert, the reason I had trouble was it was not level or square to begin with. It's still a little high in the center but I'll live with it for now. I'm interested to see how you hook up the dust collection and wiring when you get to it.
I'm with you both on the PM extension table. What was irritating to me is that the very bottom of the leg bases that came with the table, (the screw in feet), it caused the table to be too high to allow the extension table to be level with the surface of the saw.

Had to go to HD and buy some different ones in order to make it work. Getting everything level and straight was a frustrating proposition too, but it works OK for me now.
That saw looks great, and so does the shop! Have fun with that puppy!
