I built a router table (non CNC, like
this one) for constructing cabinet doors and the like. Presently I clamp the fence down to the table top with a couple of C-clamps. This works reasonably well, but can be difficult to square up with the T-track that my miter gauge rides in.
As I see it, I have two choices:
First, I could set this up like the fence on a table saw. Look at a Delta Biesemeyer or Jet XACTA fence to get a better idea of this. Basically it's a slot with a T-square. The top of the T sits in the slot and the vertical leg of the T is the fence. There is some kind of cam that locks it into position. Pros: quick and easy to set up. Cons: fence doesn't always stay square when the lock is released.
Second, I could take a page from the CNC Router book and put a rail on both ends of the table and have the fence ride on the rails. Then it would always be square to the table and the rails, within the limits of whatever slop the setup has. Pros: Always square even if it's unlocked; easy to set up. Cons: A lot more complex; How would I lock it down?
I'm soliciting input here, so feel free to brainstorm, even if you think your idea sounds a little crazy!
