So your Dad bought a new table saw!
Those excalibur fences are not that great though. They tend to be difficult to keep square over time.
Did your Dad manage to get a Canadian made saw, or a Chinese made saw?
While my father still has an important role with Funk Audio he was not involved with this equipment purchase.
I have used the Excalibur fence system and with proper maintenance, and no abuse, I find they work very well in my experience.
I am not sure where this saw was made but it is their best 10" model, and so far it is working very well for us.
