Very nice advices,
I tested with a square on the crosscut fence, but Brian's square is too small to reach the parallel fence from my outrigger fence. I also use the adjustable square for small parallel rip, but mine is 12 inches and does not work for wider cut. I also measured with a caliper the result and yes, either I am doing something wrong, or David is right and the inner edge of the sliding table is not as precise as I thought.
I am more on David's side in term of precision as when something goes wrong during assembly I prefer to eliminate all sources of error I could so I can concentrate on the pure assembly side. It took me 1 year with my "tuned" K500 and everything planed and jointed to the best of my knowledge to realize that the Kreg stuff is not up to par as some have already posted.
It might be stupid but David's solution with Brian's parallel guide and some magswitch instead of pin in the cast iron, seems like a good idea on paper, just thinking out loud.
