My earlier router table fences lacked control. I would tap one side and the other would move. Tapping is an inexact way to move something in very small increments. I’ve hit on a very inexpensive, easy to make, router adjustment system that works well. It can quickly, and easily, zero in on precise fence adjustments. This fence is attached to the table using four bolts that can be set up and removed in just a couple of minutes. So less talking and more photos; thanks to my neighbor Bill and his Nikon. If you like this blog, how about you throwing me a bone and tell me your ideas?
Here is the fence adjustment system. In the following photos, I’ll describe the design features and how they are made.
This design centers around using 1” square stock steel tubing, 1/2” bolts, 1/2” threaded steel rod and epoxy. The tubing is drilled out and plugged so the epoxy fills the tubing. The bolt is held in place with the threaded rod while the epoxy cures. Be darn sure to coat the rod with white grease so you can unscrew it. You will need to use pliers to get the rod loose. Use your tap & dye set to re-cut the threads on the bolt and nut that is encased in epoxy. That made a big improvement making the rod easier to turn.
Another important component to the adjusting system is the 2” angle iron arms that are allowed to pivot so the bolts do not bind when the fence is not parallel to the square stock tubing. Note the slots to allow the fence to slide are cut into the base of the fence, not in the table, as in most set ups. My set up is limited to a 2 1/2” travel, but that’s all I have ever needed. When I need greater distance I use my table saw fence.
This is an illustration how the pivoting arms work to prevent binding.
Now to the nuts & bolts—or just the bolts. I attached spacers, with washers, to the bolts to make them the right length to secure to the table. The spacers also serve a higher purpose, that is, they make it easier for me to handle when I screw & un-screw them into T-bolts that are attached to the under side. All bolts are 5/16” so they use the same size 1/2” socket.
Now that I have you drooling to make this fence for your shop, I have a word of warning. The only place where I could find the knobs for the threaded rods is from Grizzly. The warning is the part numbers in the catalog are wrong. The knob for the 1/2” threads is #H3462 for $1.10 ea. I was very disappointed to receive the wrong size.
And now for the finale, the feather board attachment. Nothin’ fancy, just a T-bolt attached to the back of the fence that holds a 5/16” bolt with knob.
That’s it, so how about throwin’ me that bone?
