CNC T-Track stop

After adding T track to my X-Carve CNC I was interested in a bump stop which was independent of the MDF surface. These little stops clamp into the track with 1/4-20 1/2" long hex bolts and a nut. A 7/32 socket wrench is used to tighten it into place. By placing them across the front and down one track a corner is formed. A longer bolt will still work (my pictures are using a 3/4" long bolt), but a 1/2" long one will keep the bolt below the surface of the MDF and out of the way of a tool hit.

One thing I have realized after using this a bit is that with these stop blocks installed if you want to add/remove any other track clamps you need to do so by sliding them in from all the way back. Not sure yet how big an annoyance this will be.
