Instructions
This pattern could be cut out of a number of different material thicknesses, however, I used 0.5" thick MDF, with the center polygon pocketed to a depth of 5/32". They are designed to cut easily with a 1/4" endmill, though you can use the bit of your choice.
Take the two halves, and glue together (I recommend Titebond III for MDF, it sets up STRONG and FAST). Then just slip a 1/4" hex bolt, or a special T-Track bolt, through the slot, and put one of the T-Track knobs on. Clamp away!
Don't paint, finish, or otherwise get attached to them. You WILL plow into them with your bits and cut them up. Fortunately, you can just make more!
Bonus points if you make your own knob w/ captive nut (if you do, please post it here!)
