I love to tinker and when you combine that with tool porn i.e. flipping through the catalogs, this is what you get. I have a rockler hpl router table and fence. For no good reason I wanted to make it similar to a Kreg type fence. I had a bunch of roller blade bearing lying around and a couple lengths of T-track. I used some oak scraps to make the armature that connects to the fence bracket. The armature had eight bearings which straddle the T-track. The fence is very ridged and does not deflect when moving. There is a second piece of T-track which is flipped upside down and has a tape measure affixed to it. In the fourth picture you can see the knobs underneath. This arrangement allows me to zero the ruler wherever I need it. It ended up being quite accurate. Thanks for looking.
