Been looking at a incra ls for a router table, watch thesale videos and YouTube stuff. Besides making small box joints why would aperson need 17 or 25 inch to the right of the router? Have not seen one videoshowing someone using the fence more than 5-6 inch wide box joints past therouter let alone the whole width of the ls system. Any thoughts on why someoneneeds all that room on right side of router?
