I wanted a router table that would be complimentary to the CNC machine I use on a daily basis. The criteria was a large very flat surface and a fence with micro adjuster and a dial indicator. I wanted an alternative to using the CNC for every project but did not want to lose any accuracy.
I wanted a stable flat table to start so I used some scrap LVL from a house project to create a torsion box.
The LVL are CNC cut with half laps glued and screwed. After the glue up I noticed that it was not very flat so I surfaced the torsion box on the CNC.
A 3/4 MDF skin is on the bottom bolted with socket flat head screws. The top layer is 1 inch MDF also bolted with socket flat head screws. I tapped the LVLs to receive the screws. At one point the top was better than .002 its now more like .004 which is still better than my cast iron table saw. I think it might be the finish or wood movement not sure which one.
Legs are pine and oak salvaged from a pallet.
The fence is a copy of Pat Warners fence located here:
http://patwarner.com/routerfence.html. He explains how it works better than I can so I won’t get into it.
The short version is to use the fence: make a test cut, measure what you need then dial the fence into where it should be with the dial indicator and knob.
Mine is MDF birch and Walnut. I could not find all the correct hardware so I am using a T handle Allen key and socket cap screws instead of proper handles.
This was made on a CNC.
