It usually refers to the black phenolic plastic one attached to the base. You need to take it off to mount the Rousseau or most other bases. In some cases you may need to find longer machine screws to attach the new one with as they are thicker than the black plastic one that comes on the router.

 

@username1 - Welcome to the forum Art, and no, there are no "dumb" questions. As Chuck said, the sub-base refers to the base that came attached to the router. If your Rousseau plate isn't drilled to mount to your router, use the sub-base to mark out the location for the holes.

Very obvious you have never worked with military recruits. Yes, there ARE dumb questions.

 

Ok, that's what I thought. Thanks!

 

If as Vince says you need to drill the holes in the Rousseau to mount to your router then start a new thread asking about that. There are some tips we can give you to mount it correctly. You want to get it centered to the router armature so that you can use it with guide bushings.

Just came in from finishing the job of mounting plate to Router and also mounting plate in Table.

Bought both the centering kit and the table install kit. In a rare instance, I actually read the instructions, measured-twice-and-cut-once, and both jobs came out almost 100% dead on. :grin: (this rarely happens!)

The one hole I did mis-align was the access hole for fine adjusting above the table, but it still works.

First projects:
Table insert
Perfect Dado Jig
Circle Jig
Finger Joint Jigs

 

My father always said the only dumb question was the one not asked.

 

The dumb question will always be dumb if it is not asked because it never learns the answer to the question.

 

A lot of those questions were ones we asked way back when we were just starting.
