I simply use a square MDF block to push anything through the bit. Look up Marc Sommerfeld on YouTube and watch how he does it. Much easier that alignment of tools in T-slots. The fence does not have to be parallel to anything for his method to work, and the block also acts as a backer to eliminate tearout. A small block of 3/4 MDF lasts a very long time. Cut the square a bit oversize to begin with and trim away the damaged backer part of the block. At some point it is no longer useful, so you get rid of it. You could put a handle on the block, but that isn't really necessary.
The more I do, the less I accomplish.
