I am curious. In a post earlier in this thread,. you indicated that you were about to realign your tables. How did that go. I am certain that they will align to your satisfaction.
Have you decided to upgrade to the 520. When you do, I know you'll be impressed with the new characteristics and capabilities. The ease/accuracy of setting a rip size is unbelieveable.
I aligned the table, but it was hard to move the table to drill-press mode. I'm going to try Nick's suggestion to correct this, but haven't had a chance yet. The 520 upgrade will have to wait 'til next year, I'm afraid. The boss said no this time.
