Re: Adding router extension to 3650
cutting a rabbet along the table or table edges or table support structure which abut the rails would probably be the easiest way to provide for the aluminum angle and bolt heads that will intrude into the area which will be occupied by the router extension. just leave at least 1/8" of the top in place to cover the bolt heads. that should be strong enough to support any work pieces.
there's a solution to every problem.....you just have to be willing to find it.
