Overview of The Ultimate Router Base

What People Are Saying

"After Scott showed us this base while teaching at the Chippendale School of Furniture, I knew this would be a game changer and help our students work safer, and with more control."

Anselm Frazer, Scotland

"This will make all my router operations much safer. Plus, the base has so many features all in one. I saw this in action at the Marc Adams School of Woodworking and I pre-ordered it on the spot."

Greg Zjnada, Illinois

"The longer offset gives much, much better router stability when doing edge work."

Fred Grosse, Virginia

"The router is my favorite tool (I have over 50 of them). I realized that putting all these different options into one base is a great upgrade over the standard base."

Jeff Krabbenfoft, Iowa, after Scott's AWFS class in Vegas.

Ultimate Router Base


Can I mount my grandfather’s old router?

Yes, but you will have to drill mounting holes, which is easy to do. See the video on this page, above: Mounting Non-Conforming Routers

Can I use my own template guides in this base?

Yes, as long as they are standard, THE most common PC 1-3/8 insert types. Ours are  made by the same manufacturer with very high tolerances.   Other brands might have a slight amount of wiggle. 

How can I cut a curved joint?

This system was originally designed for curve joinery. Using the large bushing and a template, you can offset the router bit to either side of the cutting seam. This is clearly explained in Scott Grove's book, Hardwood Edging and Inlay for Curved Tables published by Schiffer Books. Available at


Typos on engraving

The metric rule increments are mislabeled; they are engraved with 100mm then 200mm up to 1900mm, which is incorrect.  It should be 100mm then 110mm and so on up to 280mm. We now provide correct labels with the correct scale that you can apply yourself.

Both rulers slightly stretch ~ 1/32” over 7”, which is why we provide a new label and discount, while supplies last.

Typos on layout card

On the card, the layout holes for PC (porter cable) say B holes and should be A holes.
