Fence guide for Woodhaven router planing sled

thingiverse

I have a Woodhaven router planing sled and 3010 rail kit for planing large boards, epoxy resin castings, etc. I thought that it needed a little device to hold it squarely against the fence on one side. After some measurements and quick design work in FreeCAD, I created this.Print two of them and attach one to each side of the planing sled on the tracks that go up against the fence. Use a 1/4" bolt, a washer, and a nut (a wing nut or knob makes for easy adjustment). Adjust for just a little play and tighten it down. Now, one side will track closely to the fence. This is much easier than getting the opposite rail perfectly aligned and keeping it aligned as the base wood dimensions vary with temperature and humidity.
