Very nice build, by the looks of it you're set-up to cut some serious plate. Have you had it runnin yet?
I noticed the double spring set-up on your y-axis. Be interesting to see how that works for you. We used a similar set-up on our router table, but we went with a pivot and spring set-up. Not sure how to link previous threads to other threads, but we're under the DIY table build "Med-Pac new machine" quite a ways back.
