Router Gauge

 This weekend's scarfing showed me the need for an easier way to adjust the router's bit-depth.  

Using some scrap of red oak planking I made a stout little block.  Good weight for a little block and perfectly flat bottom.

Then I found a really old tape measure that had a millimeters scale on it.  Carefully cut it and taped it to the block using some two-sided carpet tape.  I covered the rest of the carpet tape over with duct tape.
