Template Guide Bushing Precision Sub-Base
NOTE: This is an accessory to our Plunge Base.
Our friend Pat Warner has been making our Plunge Base's acrylic sub-bases since we came out with it in 2006. I met Pat when I first started manufacturing the Micro Fence back in 1993. Over the years he has accumulated a wide line of router accessories that he makes and markets from his website www.patwarner.com. Pat has proven to be a valued ally and a generous source of information related to routers and routing.
It comes as no suprise to us that he has engineered a sub-base that improves template guide bushing set-ups. We've adopted this base as an accessory to our Plunge Base. It features counter-bored holes that allow for minor adjustment when installing the guide bushings in the base. We feel quite confident about the 'concentricity' of our motor carriage and lower aluminum base as they are CNC milled from the same fixture during manufacture. We can't however, vouch for the centricity of either the motor housing or collet structure of various manufacturer's trimmers that can be mounted in our base.
Pat's precision base provides the 'wiggle room' that can save the day when trying to align the bit to a template guide bushing. The bases are thicker (.330 + or - .010") to insure durability and come with three button-head allen drive screws that fasten them to the bottom of our plunge base.
For those that want the ultimate set-up accuracy, these bases are an asset. They are available by themselves or in a combination kit with our Precision Template Guide Bushings.
