do you have something on the underneath side that fits in the slot? - <b>Yes, I made a 3/4" runner out of Oak and set it perpendicular to the sled.</b>
what is the block with the two screws in it for? - <b>That serves two purposes. 1) It helps protect the hands and fingers and 2) it is tall enough that I use it to contact the blade guides and stop the sled from being pushed all the way though the sled.</b>
what is the blue material and what is it's purpose? - <b>That is anodized extruded aluminum specifically made for making t-slots in jigs and other devices. I got it from Rockler and it comes ini 4' lentghs and includes a number of knobs (like the one shown) and other such devices.</b>
